Abstract
Taper roll bearing retainer, is machined with roller mounting hole on retainer, roller mounting hole by above, below, side 1, side 2, inclined-plane 1 and inclined-plane 2 form, and angle is α between inclined-plane 1 and inclined-plane 2, and described α angles are 45 degree.Side 1 and side 2 respectively with being provided with undercut between above and below.The material of retainer is 08AL.Undercut is circular or square.The beneficial effects of the utility model are the reduction of the friction area of roller and retainer, reduce frictional force between the two, increase the space between roller and retainer, beneficial to the entrance of lubricating oil, high lubricating effect, caused noise when bearing runs at high speed is also reduced simultaneously, also increases the service life of bearing.
Description
Technical field
It the utility model is related to a kind of retainer, more particularly to a kind of taper roll bearing retainer.
Background technology
Bearing is responsible for the machine components of support shaft rotation, and taper roll bearing is mainly subject to radial and axial joint
Load, it is widely used in the deceleration such as automobile front and back wheel, speed changer, differential mechanism, pinion shaft, building machinery and large-scale agricultural machinery
In device.Retainer partly wraps up all or part of rolling element, and the bearing parts moved therewith, to separation roller,
Generally also guide rolling element and hold it in bearing.Rolling bearing causes bearing to send out at work, due to sliding friction
Heat and abrasion, especially under the conditions of high temperature operation, the effect of centrifugal inertial force exacerbates friction, abrasion and heating, meeting when serious
Cause retainer to burn or be broken, cause bearing cisco unity malfunction.Cavity wall of the taper roller directly with roller mounting hole contacts,
Contact surface is bigger, causes conical bearing in operation process, and friction is larger, and noise is higher, and lubricating oil is not easy to enter
Cavity is lubricated to taper roller, influences the service life of taper roll bearing.
Utility model content
The technical problem that the utility model solves is overcome the deficiencies in the prior art, there is provided one kind reduces friction, improved
The taper roll bearing retainer of lubrication.
The technical solution adopted in the utility model is taper roll bearing retainer, and roller installation is machined with retainer
Hole, roller mounting hole by above, below, side 1, side 2, inclined-plane 1 and inclined-plane 2 form, and angle is between inclined-plane 1 and inclined-plane 2
α, side 1 and side 2 respectively with being provided with undercut between above and below.The material of retainer is 08AL, and 08AL is high quality carbon
One kind of plain structural steel, the Al deoxidation killed steel cold-reduced sheets being typically used as in cold stamping sheet steel, thermal conductivity is good, friction factor
It is small, wearability is good, impact flexibility is strong, density is smaller and linear expansion coefficient and rolling element are close, machinability is excellent.Described
α angles are 45 degree.Described undercut is circular or square.
The beneficial effects of the utility model are the reduction of the friction area of roller and retainer, reduce rubbing between the two
Power is wiped, the space between roller and retainer is increased, beneficial to the entrance of lubricating oil, high lubricating effect, while also reduces axle
Caused noise when running at high speed is held, also increases the service life of bearing.
Brief description of the drawings
Fig. 1 is the section front view of the utility model taper roll bearing retainer；
Fig. 2 is A-A sectional views in Fig. 1；
Fig. 3 is B-B sectional views in Fig. 1；
In figure mark for：1- retainers, above 1a-, below 1b-, 1c- sides 1,1d- sides 2,1e- inclined-planes 1,1f- is oblique
Face 2,1g- undercuts
Embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings.Roller mounting hole, roller peace are machined with retainer 1
Hole is filled by 1a above, below 1b, side 1 (1c), side 2 (1d), inclined-plane 1 (1e) and inclined-plane 2 (1f) composition, inclined-plane 1 (1e) and
Angle is α between inclined-plane 2 (1f), side 1 (1c) and is provided with undercut 1g between 1a and following 1b above, side 2 (1d) with it is upper
Undercut 1g is provided between face 1a and following 1b.
The material of retainer 1 is 08AL.08AL is one kind of carbon constructional quality steel, is typically used as in cold stamping sheet steel
Al deoxidation killed steel cold-reduced sheets, thermal conductivity is good, friction factor is small, wearability is good, impact flexibility is strong, density is smaller and the swollen system of line
Number is close with rolling element, and machinability is excellent
Described α angles optimal angle is 45 degree.Described undercut 1g is circular or square.Installed in each roller
The corner in hole processes undercut, can effectively reduce the contact area between roller and retainer, reduces energy loss and rubs
Chafing amount, while lubricating oil can enter Bearing inner by undercut, improve the lubricant effect of bearing.
