Abstract
The invention relates to a machining method of worm shaft sheath helical teeth of a rotor spinning machine, which comprises the following steps: A. carrying out finish machining on worm shaft sheath helical teeth; B. carrying out high-frequency quenching on the tooth part of the worm shaft sheath helical teeth, wherein the top hardness of the helical teeth of the high-frequency quenching is controlled at 45-50 HRC; and C. tempering the tooth part of the worm shaft sheath helical teeth subjected to high-frequency quenching. By using the machining method, the product has small deformation, and the tooth part precision satisfies the working condition requirement; and the service life is long. The tooth surface adjacent to the tooth top is small in abrasion, the replacement period of the worm shaft sheath is prolonged, and the labor cost for maintenance of equipment is lowered. The manufacturing cost for gear grinding machining is low, and the production efficiency is greatly enhanced.
Description
Technical field
The present invention relates to the working method of worm screw axle sleeve spiral tooth, especially, relate to the work-ing life of the worm screw axle sleeve on rotor spinning machine, belong to spinning machinery processing technique field.
Background technology
On rotor spinning machine, worm screw swivel nut (as shown in Figure 1) is the joggle piece of feed roller plastics worm gear, and it drives feed roller plastics worm gear wheel, makes feed roller complete the feeding action of sliver.The work material of worm screw axle sleeve is No. 45 steel, and in operational process, the mating surface shape of worm screw axle sleeve spiral tooth and teeth portion hardness directly have influence on the work-ing life of feed roller plastics worm gear.
Fig. 2 is the situation of the spiral tooth normal wear of worm screw axle sleeve, teeth portion shade is wearing part, under this situation, the plastics worm gear of feed roller is generally about 1 year work-ing life, and (see Fig. 3 after the spiral tooth inordinate wear of worm screw axle sleeve, teeth portion shade is wearing part), the work-ing life of feed roller plastics worm gear only has about 3 months.And due to rotor spinning machine structure, as worm screw axle sleeve need be changed, then need to pull down 10 cover bearing, bearing support, end caps etc. on major axis and the axle that often saves simultaneously, for the lead aircraft device of 20 joints, require great effort again during replacement cost.
The Conventional processing methods of current rotor spinning machine worm screw axle sleeve spiral tooth has three kinds:
The first: do not do thermal treatment after the precision work of worm screw axle sleeve teeth portion, spiral tooth top hardness is about 8HRC, and tooling cost is low.But work-ing life is very short, especially the flank of tooth is near the wearing and tearing of tooth top position very fast (see Fig. 3, teeth portion shade is wearing part), and general use is no more than 1 year.As continued to use, then need frequently to change plastics worm gear.
The second: worm screw axle sleeve teeth portion precision work rear surface hard chrome plating (thickness 0.03mm), wear resistance improves, tooling cost is medium, but work-ing life does not still grow (about 1 year half), mainly the flank of tooth is near tooth top position wearing and tearing very fast (as shown in Figure 3, teeth portion shade is wearing part).
The third: integral quenching after the roughing of worm screw axle sleeve spiral tooth, then precision work roll flute.The method working accuracy is high, and surface hardness is high, long service life (being greater than 3 years), but working (machining) efficiency is low, and manufacturing cost is high.
Summary of the invention
Technical problem to be solved by this invention is the working method of the worm screw axle sleeve spiral tooth providing a kind of rotor spinning machine, can in guarantee working accuracy and work-ing life, prerequisite under cut down finished cost.
The technical scheme that the present invention solves the problem is as follows:
A working method for the worm screw axle sleeve spiral tooth of rotor spinning machine, is characterized in that:
Comprise the following steps:
A, carry out high-frequency quenching to the teeth portion of worm screw axle sleeve spiral tooth, the top Hardness Control of the spiral tooth of quenching technology is at 45-50HRC;
B, temper is carried out to the teeth portion of the worm screw axle sleeve spiral tooth through high-frequency quenching.
Further, the technique of described high-frequency quenching is:
The gap of heat induced circle and workpiece remains on 1.5--2mm, high-frequency quenching frequency 300kHz, electric current 400A, 4--5 second heat-up time.
Further again, described temper is incubated 1 hour under the condition of tempering temperature 180 DEG C.
Compare with three kinds of Conventional processing methods of above-mentioned worm screw axle sleeve spiral tooth, beneficial effect of the present invention is:
1, deformation of products is little, and teeth portion precision meets working condition requirement;
2, long service life (about 3 years).The wearing and tearing of the flank of tooth near tooth top position little (see Fig. 4, teeth portion shade is part of hardening), the replacement cycle of worm screw axle sleeve extends, and reduces the cost of labor of maintenance of the equipment;
3, without the low cost of manufacture of roll flute processing, production efficiency improves greatly.

Fig. 2 is the situation of spiral tooth normal wear, and teeth portion shade is wearing part.
Fig. 3 is the situation of the spiral tooth inordinate wear of worm screw axle sleeve, and teeth portion shade is wearing part.
