Abstract
The utility model discloses a roller bearing, personally experience sth. Part of the body and cup joint the bearing case at dabber body both ends including the dabber, the dabber body is including first dabber, second dabber and shaft coupling, shaft coupling and first dabber, second dabber close -fitting, the shaft coupling passes through the parallel key with first dabber and second dabber and is connected, the bearing case surface is equipped with hatching knurling. The utility model discloses simple structure, reasonable in design, the dabber body adopt the split type structure of first dabber and second dabber, convenient processing, installation, cost and time are practiced thrift in convenient change when the one end dabber damages, and adopt the parallel key transmission between the dabber body and the shaft coupling, do not produce the displacement between guarantee dabber and the shaft coupling, increase machine operation power, the bearing case surface is equipped with hatching knurling, and yarn and other part are conveniently cup jointed to the frictional force of increase and bearing case surface, promote the synchronism among the spinning process, improve the spinning quality, and are difficult to rust.
Description
Technical field
The utility model belongs to textile workpiece technical field and in particular to a kind of roller bearing.
Background technology
Roller bearing is mainly used in weaving loom, is made up of the cartridge housing at mandrel and its two ends, it is characterized in that two end axles
Hold a ball raceway groove of shell inwall, ball road structure is changed to two ball raceway grooves and, its with mandrel on two bar ditch
Respectively relatively, the ball of retainer is loaded in raceway groove in road, so reduces ball to the normal pressure of cartridge housing and frictional force, significantly subtracts
Little abrasion, reduces radial and axial clearance, can largely improve the performance and used life of upper roller bearing.
Traditional textile roller bearing surface is smooth, and frictional force is little, in spinning, drawing runs, there is smooth, synchronism
Difference, affects spinning quality, and smooth surface easily produces rust staining；The shaft core of traditional textile roller bearing is integral type knot
Structure, one end shaft core is damaged, and just can only change whole roller bearing, cause very big waste.
Utility model content
In order to make up the deficiencies in the prior art, the utility model provides a kind of technical scheme of roller bearing.
A kind of described roller bearing, including mandrel body and the cartridge housing being socketed in mandrel body two ends, mandrel body and bearing
Between shell, retainer is set, is provided with ball in described retainer, cartridge housing is provided with end cap away from one end of mandrel body, its feature exists
In：Described mandrel body includes the first mandrel, the second mandrel, shaft coupling and flat key, described shaft coupling and the first mandrel, the second mandrel
Close-fitting, shaft coupling is connected by flat key with the first mandrel and the second mandrel；Described cartridge housing outer surface is provided with hatching knurling.
A kind of described roller bearing it is characterised in that：It is socketed rubber layer outside described cartridge housing.
A kind of described roller bearing it is characterised in that：It is socketed glass layer outside described rubber layer.
A kind of described roller bearing it is characterised in that：It is provided with sealing ring between described mandrel body and cartridge housing.
The utility model structure is simple, reasonable in design, and mandrel body adopts the split-type structural of the first mandrel and the second mandrel,
Convenient processing, install, mandrel is convenient for changing when damaging at one end, cost-effective adopt and time, and mandrel body and shaft coupling between
Connected with flat key, ensure and do not produce displacement between mandrel and shaft coupling, increase machine operation power；Cartridge housing outer surface is provided with reticulate pattern
Annular knurl, increases the frictional force with cartridge housing outer surface, the convenient synchronization being socketed yarn and miscellaneous part, lifting in spinning process
Property, improve spinning quality, and be not easy to get rusty.
Brief description
Fig. 1 is the utility model structural representation；
In figure：1- mandrel body, 10- first mandrel, 11- second mandrel, 12- shaft coupling, 13- flat key, 2- cartridge housing, 3- protects
Hold frame, 4- ball, 5- end cap, 6- rubber layer, 7- glass layer, 8- sealing ring.
Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.
As shown in figure 1, a kind of roller bearing, including mandrel body 1 and the cartridge housing 2 being socketed in mandrel body 1 two ends, mandrel body
Between 1 and cartridge housing 2, retainer 3 is set, is provided with ball 4 in described retainer 3, cartridge housing 2 is provided with away from one end of mandrel body 1
End cap 5.
Described mandrel body 1 is Split type structure, including the first mandrel 10, the second mandrel 11, shaft coupling 12 and flat key 13, described
Shaft coupling 12 inwall and the outer wall close-fitting of the first mandrel 10 and the second mandrel 11, shaft coupling 12 inwall and the first mandrel 10 and second
Connect also by flat key 13 between mandrel 11.Mandrel body 1 is designed to Split type structure, convenient processing, assembling and replacement, reduces and produces
Cost；Connected using flat key 13, ensure and do not produce displacement between the first mandrel 10, the second mandrel 11 and shaft coupling 12, increase machine
Tool operating power.
Cartridge housing 2 outer surface is provided with hatching knurling, increases the frictional force with cartridge housing 2 outer surface, convenient socket yarn and
Miscellaneous part, the synchronism in lifting spinning process, improves spinning quality, and is not easy to get rusty.
As optimizing structure, described cartridge housing 2 is outer to be socketed rubber layer 6, and rubber layer 6 has good compressibility, in pressure
In the presence of produce compressibility deformation, equably can grip fiber, and not damage fiber.
As optimizing structure, the outer socket glass layer 7 of described rubber layer 6, glass layer 7 have good wearability and
Antistatic behaviour.
As optimizing structure, it is provided with sealing ring 8 between described mandrel body 1 and cartridge housing 2, sealing ring 8 plays sealing and dustproof
Effect.
Shown in the above and in figure is only preferred embodiment of the present utility model.It should be pointed out that for this area
Those of ordinary skill for, on the premise of without departing from the utility model principle, some modifications and improvement can also be made, this
Also should be regarded as belonging to protection domain of the present utility model a bit.
