Abstract

The utility model discloses a gear case of a short fiber two-for-one twister. The gear case comprises an S-twist and Z-twist reversing gear (1), a first twist of yarn change gear (10) and a second twist of yarn change gear (12), wherein a cylinder roller bearing (3) and a first deep groove ball bearing (4) are fixed in the inner bore of a bearing pedestal (2), the cylinder roller bearing (3) and the first deep groove ball bearing (4) are fixed on a shaft (5), and the S-twist and Z-twist reversing gear (1) is fixed on the shaft (5). The gear case of the short fiber two-for-one twister solves the problem that an S-twist and Z-twist reversing gear shaft is easy to abrade and has high processing difficulty, has small possibility of tooth breakage of the S-twist and Z-twist reversing gear, moreover, needle roller bearings do not need to be added or changed in the reversing gear, thereby reducing the maintenance cost and prolonging the service life.

Description

Short fiber two-for-one twister gear-box

Technical field:

The utility model two-for-one twister technical field is more specifically to a kind of gear-box of two-for-one twister.

Background technology:

As shown in Figure 1, existing short fiber two-for-one twister gear-box drives worm gear B by worm screw A and rotates, and drives the twist transformation gear D by S sth. made by twisting and Z sth. made by twisting tumbler gear 101, transition gear C again.

S sth. made by twisting and Z sth. made by twisting tumbler gear 101 endoporus are fixed on the outer ring of needle bearing 102 as shown in Figure 2, needle bearing 102 is enclosed within on the gear shaft 103 then, pressing needle bearing 102 by pad wheel 106, elastic collar 105 is pressing pad wheel 106 and blocking to be positioned on the gear shaft 103, and gear shaft 103 is fixedly connected on the bearing block 104 by screw 107.Its weak point is: 1, because S twists with the fingers and Z sth. made by twisting tumbler gear 101 need install needle bearing 102 additional, so S twists with the fingers and the endoporus processing request height of Z sth. made by twisting tumbler gear 101, also easy to wear.2, simultaneously, S sth. made by twisting and Z sth. made by twisting tumbler gear 101 endoporus need to strengthen, and after the increasing, S twists with the fingers and Z sth. made by twisting tumbler gear 101 intensity diminish, and S sth. made by twisting and Z sth. made by twisting tumbler gear 101 often collapse tooth in the use.3, add the copper sheathing sleeve on axle in the middle of the transition gear C, the one, increased equipment cost, the 2nd, copper sheathing is easy to wear, needs often to change, the 3rd, copper sheathing wearing and tearing back influences service precision.

The utility model content:

The purpose of this utility model is exactly the deficiency at prior art, and provide a kind of short fiber two-for-one twister gear-box, it has solved, and S twists with the fingers and Z twists with the fingers the easy to wear and high problem of difficulty of processing of tumbler gear, the difficult S of generation twists with the fingers and Z sth. made by twisting tumbler gear collapses tooth, its transition gear does not need to change copper sheathing, reduce maintenance cost, improved service life.

Technology solution of the present utility model is as follows:

Short fiber two-for-one twister gear-box, comprise that S twists with the fingers and Z twists with the fingers tumbler gear, the first twist transformation gear and the second twist transformation gear, be fixed with the cylinder roller bearing and first deep groove ball bearing in the inner hole of bearing seat, the cylinder roller bearing and first deep groove ball bearing are fixed on the axle, and S twists with the fingers and Z sth. made by twisting tumbler gear is fixed on the axle.

Described hole is pressing the cylinder roller bearing and first deep groove ball bearing to be fixed in the inner hole of bearing seat with elastic scheibe, the spacer sleeve is on axle, S sth. made by twisting and Z sth. made by twisting tumbler gear are enclosed within and are compressed on the axle between spacer and the stop washer, and the circle spiral shell is screwed onto axle and goes up and pressing stop washer.

The described first twist transformation gear, the second twist transformation gear are fixed on the twist transformation axle by flat key, form dead eye on the casing, the inner ring of two second deep groove ball bearings is fixed on the twist transformation axle, and the outer ring of second deep groove ball bearing is fixed in the dead eye.

Described gland is pressing two second deep groove ball bearings that are stacked together to be fixed on the casing by screw.

The beneficial effects of the utility model are: 1, because S twists with the fingers and Z sth. made by twisting tumbler gear directly is fixed on sth. made by twisting on reversing shaft, saved the needle bearing of inner ring, S twists with the fingers and Z twists with the fingers the tumbler gear endoporus needn't to adorn the needle bearing axle be not the difficulty of processing that bearing cone has reduced spool like this, increased the inner wall thickness that S sth. made by twisting and Z twist with the fingers tumbler gear simultaneously, improve its intensity, can not collapse the tooth phenomenon.

2, transition gear does not need to change copper sheathing, has reduced maintenance cost, has improved service life.
