Abstract
The utility model discloses a kind of internal spiral oil guide slot retainer, belong to retainer technical field.It comprises retainer body, retainer inner ball surface has the oil guide slot of internal spiral, the helix angle of oil guide slot is 30 degree, and the groove face width of oil guide slot is 0.4 ~ 0.45mm, groove depth is 0.25 ~ 0.3mm, and oil guide slot is formed by the milling in retainer inner ball surface of long handle milling cutter.The utility model has the advantage of: mainly oil guide slot and retainer are carried out Integration Design, when retainer contacts with star sleeve outer spherical surface, butter are stored in spiral oil guide groove, greatly strengthen the lubrication effect of retainer and shell, thus reduce retainer sphere abrasion, increase substantially the working life of retainer, the working life of truck drive shaft and retainer is improved greatly, expands the application market of product.
Description
Technical field
The utility model relates to retainer technical field, is specially a kind of internal spiral oil guide slot retainer.
Background technique
Existing vehicle transmission retainer inner ball surface is continuous full circle, its inner ball surface in constant velocity universal joint with the contact friction of star sleeve outer spherical surface, greatly reduce the working life of universal joint, in order to the demand making retainer can meet market, need to improve existing retainer
In life, no matter be automobile, household electrical appliances or other products, its mechanical drive shaft all needs lubricant oil to lubricate in the course of the work, this just needs to arrange oil guide slot, oil guide slot mainly gathers circulation to the lubricant oil of drive bearing, it is not only wanted can lubricating bearings, can also reduce friction and anticorrosion.
Existing oil guide slot has self-existent component, also has by directly milling out oil guide slot at transmission shaft inwall, and in order to solve the existing defect problem of retainer, our main mentality of designing is merged oil guide slot and retainer.
Model utility content
The utility model for the technical problem that solves for providing a kind of internal spiral oil guide slot retainer, oil guide slot and retainer are mainly carried out Integration Design by it, not only structure is simple, practical exquisite for it, and structural stability, reduce retainer inner ball surface in constant velocity universal joint with the contact friction of star sleeve outer spherical surface, the working life of truck drive shaft and retainer is improved greatly, expands the application market of product.
The utility model technical solution problem adopts following technological scheme:
A kind of internal spiral oil guide slot retainer is provided, it comprises retainer body, it is characterized in that: the oil guide slot described retainer inner ball surface having internal spiral, and the helix angle of described oil guide slot is 30 degree, the groove face width of described oil guide slot is 0.4 ~ 0.45mm, and groove depth is 0.25 ~ 0.3mm.
As preferred embodiment, described oil guide slot is formed by the milling in retainer inner ball surface of long handle milling cutter.
The utility model compared with prior art, its beneficial effect is: mainly oil guide slot and retainer are carried out Integration Design, when retainer contacts with star sleeve outer spherical surface, butter are stored in spiral oil guide groove, greatly strengthen the lubrication effect of retainer and shell, thus reduce retainer sphere abrasion, increase substantially the working life of retainer, the working life of truck drive shaft and retainer is improved greatly, expands the application market of product.
Accompanying drawing explanation
Fig. 1 is front sectional view of the present utility model.
Fig. 2 is vertical view cutaway drawing of the present utility model.
Fig. 3 be Fig. 2 mark A-A part partial enlarged view.
Number in the figure: 1 is retainer, 11 is oil guide slot, and 12 is inner ball surface, and 13 is helix angle.
Embodiment
The technological means realized to make the utility model, character of innovation, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1-Figure 3, a kind of internal spiral oil guide slot retainer, it comprises retainer 1 body, and 12 oil guide slot 11 having an internal spiral in retainer 1 inner ball surface, the helix angle 13 of oil guide slot is 30 degree, and the groove face width of oil guide slot 11 is 0.4mm, and groove depth is 0.3mm.
Oil guide slot 11 is formed by the milling in retainer inner ball surface of long handle milling cutter.
This internal spiral oil guide slot retainer in actual use, when retainer contacts with star sleeve outer spherical surface, in spiral oil guide groove, store butter, greatly strengthen the lubrication effect of retainer and shell, thus reduce retainer sphere abrasion, increase substantially the working life of retainer.
More than show and describe basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
