   Reducer, such as equipment, transmission equipment, precision planetary gear reducer to adjust the common method of professionals to adjust the gap method, the error compensation method, parts repair to change the law and with a total of four kinds of parts method.
    First, adjust the gap method
    In the spiral lift transmission machinery and equipment, the prevalence of the relative motion of the internal parts. There is movement there is friction, there is friction necessary to cause the relevant parts of size, shape and surface quality, resulting in wear and tear, increased with the gap between the related parts. Only by adjusting the gap after the gap over a reasonable range, in order to ensure the accuracy of the relative motion between the parts. Therefore, the moving parts of machinery and equipment, general design gap adjustment mechanism. Gap adjusting mechanism to adjust the gap is to ensure equipment accuracy and stability of the most common and easiest method.
    (1) deceleration of the machine spindle rotation accuracy adjustment
    Reducer spindle rotation accuracy in the machining error of the spindle itself to meet the requirements under the premise, in general, to a large extent by the bearing to decide. Spindle Error adjustment key is to tune the bearing clearance. To maintain a reasonable amount of bearing clearance on the performance and bearing life in spindle assembly is of great significance. Rolling is a larger gap, not only cause the load to focus on the role of in force on the direction of the rolling element above, and in the bearing outer raceway contacts generated at the severe stress concentration shorten the bearing life, but also the spindle centerline drift phenomenon is easy to cause the vibration of the spindle assembly. Rolling adjustment to pre-load bearing internal to produce a certain amount of interference caused by the rolling element and the outer raceway contact at a certain amount of elastic deformation, in order to improve the rigidity of the bearing. Is naturally extremes meet, if the pre-load is too large, will inevitably lead to increased wear of rolling bearings, the occurrence of a short period of time damage phenomena.
    2 precision adjustment of rail-oriented
    For general machinery and equipment, the gap between the slide rail is appropriate, usually 0.03mm or 0.04mm thick feeler gauge inserted in the end parts of the inspection, the required insertion depth should be less than 20mm. If the rail gap is inappropriate, must be adjusted in a timely manner.
    (3) the gap between the worm screw lift screw and nut adjustment
    Screw-nut drive screw lift is one of the most common organization of the linear motion. With screw and nut, it is difficult to be no gap. Especially after the use of a stage, due to wear, but will increase the gap, affect the device to work. Therefore, the equipment repair process, attention is necessary to eliminate the gap between the screw and nut.

Suture has been cut or traumatic fracture tissue, organs together or rebuild its channel to restore its function. Is one of the basic conditions to ensure good healing is also an important surgical operation techniques. Surgical suture and knot

Different parts of the tissues and organs need a different approach to suture. The Fosun suture can be used Needle Holders can also be hand directly to get the straight needle, in addition to skin stapler, gastrointestinal stapler, closed, etc.. The basic steps of the suture to the skin was sutured as an example to illustrate the steps of the suture:
Edit this paragraph
Suture steps

(1) needle; (2) needle injection; (3) a pin; (4) clip needle
(1), suture needle left hand toothed forceps, lift the skin edge, the right hand sticking the needle clamp (law enforcement in the previous section), precession of the wrist and arm strength from the outside, along the curvature of the needle puncture into the skin, subcutaneous from side of the skin flap to wear clothing.
(2), the needle injection available toothed forceps along the needle front end along the curvature of the needle, pull, while holding the rear of the needle from the needle homeopathic forward;
(3), the needle, the folder needle when the needle to be pulled out completely, the resistance has been very small, you can release the needle holder, single tweezers needle continue to pull outside, needle holder
Quick switch to re-clip the needle body (1/3 arc Department), to completely pull out the needle and knotted by the first assistant, second assistant cut the line to complete the stitching step

(1), to ensure good involution of the suture wound or wounds. The suture should be layered, stitched at the anatomical level of the organization s strict organizational hierarchy, not to get involved or sewn into the other organizations, do not leave a residual cavity to prevent the effusion of blood clots and infection. Suture the wound edge distance and pin spacing must be uniform, so it looks beautiful, but more importantly, by force and share the same tension and tight stitching, and will not leak.
(2), pay attention to the tension of the suture. The tightness of the ligature Fosun suture the incision edge is closely connected to the subject, not tight, in other words, sooner or later, good or bad wound healing is not completely proportional to the degree of close, too tight too loose can lead to poor healing. Wound tension should be carried out suture wounds such as the defect is too large, may be considered to transfer the skin flap or skin graft.
(3), the choice of suture and suture needle to be appropriate. Sterile incision or less contaminated wound debridement and disinfection cleaning treatment can be used silk, wound infection or serious pollution of the choice of absorbable suture, vascular anastomosis should select the corresponding model without damage needlework.
Stitched classification of commonly used suture suture method MEDICAL EDUCATION Education Network to collect There is no uniform classification of the joint relationship of the organization is divided into simple suture, eversion suture, inverting suture into three categories; each class consecutive or not suture suture is divided into intermittent and continuous suture of two kinds; the position relationship between the sutures and suture organization is divided into horizontal suture, vertical suture; sometimes will these situations combined with the name . Purse-string suture when the suture form is divided into half purse-string suture U suture, eight suture, T-suture Y-shaped suture. There are also used to suture made of a special purpose, such as suture, intradermal suture, and hemostasis.

Interrupted vertical mattress suture varus
(2), turn interrupted horizontal mattress suture: also known as Ho Wales (with Halsted) suture used for the gastrointestinal tract lined stitching.
Interrupted inverted horizontal mattress suture
(3), continuous horizontal mattress lined with inverted suture: suture, also known as Cushing s (Cushing s), such as the gastrointestinal tract lined stitching.
Continuous horizontal mattress lined with inverted suture
(4), turn continuous full-thickness horizontal mattress suture technique: also known as Cornell (Connells) suture, such as the gastrointestinal tract layer suture.
Continuous horizontal mattress layer inversion suture
(5), purse-string suture method: at the tissue surface to the ring one week of continuous suture, ligation center turn embedded within a smooth surface is conducive to healing. Small incision in the gastrointestinal tract or eye of a needle off, and the embedding of the appendix stump fistula in the organ fixation.
Purse-string suture
(6), semi-ring suture: common in the duodenum of residual corner, the embedding of the gastric stump corner turn and so on.
Semi-purse-string suture (bottom corner of the duodenal stump embedded)
3 valgus suture method
The wound edge eversion suture or anastomosis of the cavity to keep it smooth, such as vascular Fosun suture or anastomosis.
(1), interrupted vertical mattress eversion suture technique: such as the relaxation of the skin suture.
Interrupted vertical mattress the valgus suture method

Interrupted horizontal mattress eversion suture
(3), continuous horizontal mattress eversion suture technique: used for vessel wall anastomosis.
Eversion suture continuous horizontal mattress
(4) suture method
Suture tissue tension, poor general condition, in order to prevent wound dehiscence can use this method, mainly used to reduce tension of the abdominal incision. Choice of coarse silk or stainless steel wire sutures at a distance of a margin of 2-2.5cm at the needle, after by abdominal rectus sheath and peritoneum to go out to the skin the needle, to ensure the accuracy of the level, but also Avoid damage organs. Suture between the distance of 3-4cm, the closure of the rectus sheath or fascia should be slightly wider than the skin. Make it bear more wound tension, suture through a piece of rubber tubing or gauze bolsters before ligation to prevent skin is torn apart, ligation Never too tight, so as not to affect the blood supply.
Intradermal suture
Can be divided into intermittent and continuous suture two intradermal, intradermal intradermal suture application of Ophthalmology small triangular needle, a small Needle Holders and 0 silk. Suture essentials: the needle from one end of the incision, and then alternately through the skin of both sides of the incision edge through the other end of the incision, has been sewn into the piercing, and the final tightening, the ends can be used as a bow or a small ball of gauze pad. Exposed skin incision suture, such as the neck thyroid incision. The quality of the stitching and the subcutaneous tissue closure density, the level of co-related. Such as incision tension, subcutaneous suture on the rope to the poor should not be using this method. Advantages of this method is stitched Hao, as early suture removal, healing scars and beautiful.
