Abstract
The invention discloses a kind of structure improved dominant draft roller shaft bearing, bearing block is provided with for the fixing circular groove of bearing 7, described bearing seat is respectively equipped with the step longitudinally sunk in the two opposite sides of circular groove radial direction, also be provided with first, two blocks, first, two blocks can dismantle the step lateral wall being fixed on bearing block both sides respectively, first, two blocks are longitudinally higher than the height of bearing block step, first, two blocks and the step of bearing block both sides form the channel form gap axially parallel with circular groove respectively, the present invention is by making Split type structure by dominant draft roller shaft bearing, even if occur first, the phenomenon that two blocks lost efficacy, also local replacing can be carried out easily, avoid the phenomenon that bearing block entirety is scrapped, save replacement cost, improve replacing speed and production efficiency, simultaneously by first, two block material change steel into, improve bearing strength, extend service life.
Description
Technical field
The present invention relates to a kind of dominant draft roller shaft bearing, particularly one structure improved dominant draft roller shaft bearing.
Background technology
Speed frames are by the drawing-off of ripe bar through 5 ~ 12 times, and add the suitable twist, make it have some strength, to bear a kind of equipment of reeling roving and the tension force on fine spining machine during unwinding.The drafting multiple of Speed frames 5 ~ 12 mainly completes in main drawing area, and dominant draft roller shaft bearing not only plays roller bearing, lower pin bar, the cotton device supporting role of two road bundles, but also has influence in spinning process the adjustment of parameter of spacing.Existing dominant draft roller shaft bearing is foundry goods monolithic construction, and the front catch that lower pin bar installs notch just there will be phenomenon of rupture in short time work, has had a strong impact on production efficiency and roving yarn quality.
Summary of the invention
In order to overcome above-mentioned defect, the invention provides a kind of structure improved dominant draft roller shaft bearing, this structure improved dominant draft roller bearing holder structure is simple, firm, convenient for assembly, low cost of manufacture, long service life.
The present invention in order to the technical scheme solving its technical problem and adopt is: a kind of structure improved dominant draft roller shaft bearing, bearing block is provided with for the fixing circular groove of bearing, described bearing seat is respectively equipped with the step longitudinally sunk in the two opposite sides of circular groove radial direction, also be provided with first, two blocks, first, two blocks can dismantle the step lateral wall being fixed on bearing block both sides respectively, described first, the structure that two blocks can dismantle the step lateral wall being fixed on bearing block both sides is respectively: the step lateral wall of bearing block both sides is provided with some screwed holes, first, two blocks are provided with the countersunk head corresponding with screwed hole position and quantity and bore a hole, also be provided with sunk screw, sunk screw is through first, countersunk head perforation on two blocks and the screw hole on bearing block, the head of sunk screw is just placed in first, in the countersunk head of two block countersunk head perforation, first, two blocks are longitudinally higher than the height of bearing block step, first, two blocks and the step of bearing block both sides form the channel form gap axially parallel with circular groove respectively, this channel form gap be able to be used for accommodating and support Speed frames main drawing area lower pin bar and the cotton device strut of two road bundles, in long-time use procedure, when first, when there is fracture in two blocks, only need to disassemble and more to renew, without the need to changing whole bearing block, save replacement cost, improve replacing speed and production efficiency.
As a further improvement on the present invention, first and second block described is all rectangle structure, and thickness is 6mm.
As a further improvement on the present invention, first and second block described exceeds bearing block height 2mm, and first and second dog height is consistent.
As a further improvement on the present invention, first and second block described is steel material, improves its bearing strength.
The invention has the beneficial effects as follows: the present invention is by making Split type structure by dominant draft roller shaft bearing, even if there is the phenomenon that first and second block lost efficacy, also local replacing can be carried out easily, avoid the phenomenon that bearing block entirety is scrapped, save replacement cost, improve replacing speed and production efficiency, change first and second block material into steel simultaneously, improve bearing strength, extend service life.

Detailed description of the invention
Embodiment: a kind of structure improved dominant draft roller shaft bearing, bearing block 2 is provided with for the fixing circular groove of bearing 7, the two opposite sides that described bearing block 2 is positioned at circular groove radial direction are respectively equipped with the step longitudinally sunk, also be provided with first, two blocks 1, 3, first, two blocks 1, 3 can dismantle the step lateral wall being fixed on bearing block 2 both sides respectively, first, two blocks 1, 3 longitudinally higher than the height of bearing block 2 step, first, two blocks 1, 3 form the channel form gap axially parallel with circular groove respectively with the step of bearing block 2 both sides, this channel form gap be able to be used for accommodating and support Speed frames main drawing area lower pin bar 5 and the cotton device strut 6 of two road bundles, in long-time use procedure, when first, two blocks 1, during 3 appearance fracture, only need to disassemble and more to renew, without the need to changing whole bearing block 2, save replacement cost, improve replacing speed and production efficiency.
First and second block 1,3 described is all rectangle structure, and thickness is 6mm.
First and second block 1,3 described exceeds bearing block 2 height 2mm, and first and second block 1,3 is highly consistent.
The structure that first and second block 1,3 described can dismantle the step lateral wall being fixed on bearing block 2 both sides is respectively: the step lateral wall of bearing block 2 both sides is provided with some screwed holes, first and second block 1,3 is provided with the countersunk head corresponding with screwed hole position and quantity and bores a hole, also be provided with sunk screw 4, sunk screw 4 is through the countersunk head perforation on first and second block 1,3 and the screw hole on bearing block 2, and the head of sunk screw 4 is just placed in the countersunk head of first and second block 1,3 countersunk head perforation.
First and second block 1,3 described is steel material, improves bearing strength.
