Abstract
The invention discloses a main drawing roller bearing seat with an improved structure. The bearing seat is provided with a circular-arc-shaped groove which is used for fixing a bearing 7. Longitudinally depressed steps are respectively arranged on two opposite sides of the bearing seat in the radial direction of the circular-arc-shaped groove. The bearing seat is additionally provided with a first stop block and a second stop block. The first stop block and the second stop block can be respectively disconnected from and fixedly connected with external side walls of the steps on the two sides of the bearing seat. The longitudinal height of the first stop block and the second stop block is larger than the height of the steps of the bearing seat. The first stop block, the second stop block and the steps on the two sides of the bearing seat respectively form groove-shaped gaps which are in parallel with the axial direction of the circular-arc-shaped groove. Since the main drawing roller bearing seat is designed to be in a split structure, even though the situation that the first stop block and the second stop block are failed, local replacement can still be conveniently conducted, the problem that the entire bearing seat is abandoned is avoided, the replacement cost is saved and the replacement speed and the production efficiency are improved; and since the materials for making the first stop block and the second stop block are changed to be steel, the bearing strength is improved and the service life is prolonged.
Description
Technical field
The present invention relates to a kind of dominant draft roller shaft bearing, particularly a kind of structure improved dominant draft roller shaft bearing.
Background technology
Speed frames are with ripe the drawing-off through 5～12 times, and add the suitable twist, make it have certain intensity, to bear reeling roving and a kind of equipment of the tension force during unwinding on fine spining machine.The drafting multiple of Speed frames 5～12 is mainly finished at 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 on the adjusting of the parameter of spacing in the spinning process.Existing dominant draft roller shaft bearing is the foundry goods monolithic construction, and the preceding catch that lower pin bar is installed notch phenomenon of rupture will occur in short time work, had a strong impact on production efficiency and roving yarn quality.
Summary of the invention
In order to overcome above-mentioned defective, 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 for the technical scheme that solves its technical problem and adopt is: a kind of structure improved dominant draft roller shaft bearing, bearing block is the circular groove that is provided with for bearing fixing, described bearing seat is respectively equipped with the step that vertically sink in circular groove two opposite sides radially, also be provided with first, two blocks, first, two blocks can be dismantled the step lateral wall that is fixed on the bearing block both sides respectively, first, two blocks vertically are higher than the height of bearing block step, first, the step of two blocks and bearing block both sides forms the channel form gap with the circular groove axially parallel respectively, this channel form gap be able to be used for ccontaining and support Speed frames main drawing area lower pin bar and the cotton device strut of two road bundles, in long-time use, when first, when fracture appears in two blocks, only need disassemble getting final product of more renewing, need not to change whole bearing block, save replacement cost, improved replacing speed and production efficiency.
As a further improvement on the present invention, described first and second block all is a rectangle structure, and thickness is 6mm.
As a further improvement on the present invention, described first and second block exceeds bearing block height 2mm, first and second dog height unanimity.
As a further improvement on the present invention, the structure that described first and second block can be dismantled the step lateral wall that is fixed on the bearing block both sides respectively is: the step lateral wall of bearing block both sides is provided with some screwed holes, first and second block is provided with the countersunk head perforation corresponding with screwed hole position and quantity, also be provided with sunk screw, the countersunk head perforation that sunk screw passes on first and second block is spirally connected with screwed hole on the bearing block, and the head of sunk screw just is placed in the countersunk head of first and second block countersunk head perforation.
As a further improvement on the present invention, described first and second block is a steel material, has improved its bearing strength.
The invention has the beneficial effects as follows: the present invention is by making the branch body structure with dominant draft roller shaft bearing, even first and second block failure phenomenon occurs, also can carry out local replacing easily, the phenomenon of having avoided bearing block integral body to scrap, save replacement cost, improved replacing speed and production efficiency, changed first and second block material into steel simultaneously, improve bearing strength, prolonged service life.

The specific embodiment
Embodiment: a kind of structure improved dominant draft roller shaft bearing, bearing block 2 is to be provided with the circular groove of fixing for bearing 7, described bearing block 2 is positioned at circular groove two opposite sides radially and is respectively equipped with the step that vertically sink, also be provided with first, two blocks 1,3, first, two blocks 1,3 can dismantle the step lateral wall that is fixed on bearing block 2 both sides respectively, first, two blocks 1,3 vertically are higher than the height of bearing block 2 steps, first, two blocks 1,3 form channel form gap with the circular groove axially parallel respectively with the step of bearing block 2 both sides, this channel form gap be able to be used for ccontaining 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, when first, two blocks 1, during 3 appearance fractures, only need disassemble getting final product of more renewing, need not to change whole bearing block 2, save replacement cost, improved replacing speed and production efficiency.
Described first and second block 1,3 all is a rectangle structure, and thickness is 6mm.
Described first and second block 1,3 exceeds bearing block 2 height 2mm, and first and second block 1,3 is highly consistent.
The structure that described first and second block 1,3 can be dismantled the step lateral wall that is fixed on bearing block 2 both sides respectively is: 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 perforation corresponding with screwed hole position and quantity, also be provided with sunk screw 4, the countersunk head perforation that sunk screw 4 passes on first and second block 1,3 is spirally connected with screwed hole on the bearing block 2, and the head of sunk screw 4 just is placed in the countersunk head of first and second block 1,3 countersunk heads perforation.
Described first and second block 1,3 is a steel material, has improved bearing strength.
