Abstract
The utility model discloses a kind of reinforced nylon retainers, including keeping frame body using ring-type made of nylon material, if being uniformly arranged dry bulb pocket hole on the cyclic annular circumferencial direction for keeping frame body, it is characterized in that, being provided with reinforcing rib on the outer circumference surface of the cyclic annular holding frame body between adjacent ball pocket hole.The utility model structure optimization, intensity increase, performance boost, are resistant to high revolving speed, and resistance to top load extends the service life of bearing, meet the performance requirement of steering system four-point contact ball of new generation.
Description
Technical field
The utility model relates to bearing retainer technical field more particularly to a kind of reinforced nylon retainers.
Background technique
As industrial technology is reformed and is promoted, four-point contact ball is widely used, not only to bear top load, also want
Bear high revolving speed.Therefore, to the double half inner ring four-point contact ball retainer overall performance requirements of steering system of new generation
It is significantly promoted, the conventional unbearable top load of retainer of conventional four-point contact ball and the requirement of high revolving speed.
The utility model has carried out beneficial exploration and trial thus, has found result of the above problems, below will
The scheme to be introduced is generated under this background.
Utility model content
The technical problem to be solved by the utility model is to for existing four-point contact ball with conventional retainer without
Method bears the problem of top load and requirement of high revolving speed and provides a kind of reinforced nylon retainer, to prevent steel ball from retainer ball
Pocket slides in hole, improves the service life of bearing.
The technical issues of the utility model is solved can be realized using following technical scheme:
A kind of reinforced nylon retainer, including frame body is kept using ring-type made of nylon material, in the cyclic annular guarantor
Dry bulb pocket hole is uniformly arranged on the circumferencial direction of frame body if holding, which is characterized in that the cyclic annular holding between adjacent ball pocket hole
Reinforcing rib is provided on the outer circumference surface of frame body.
In a preferred embodiment of the utility model, fore shaft, the diameter of the fore shaft are provided in each ball pocket hole
Less than or equal to 0.97 times steel ball size, so that the self-locking steel ball of fore shaft, prevents steel ball from sliding out from ball pocket hole.
Due to using technical solution as above, the utility model has the beneficial effects that: the utility model structure optimization,
Intensity increases, performance boost, is resistant to high revolving speed, and resistance to top load extends the service life of bearing, meets steering system of new generation
With the performance requirement of four-point contact ball.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment
Or attached drawing needed to be used in the description of the prior art is briefly described, it should be apparent that, the accompanying drawings in the following description is only
It is some embodiments of the utility model, for those of ordinary skill in the art, in the premise not made the creative labor
Under, it is also possible to obtain other drawings based on these drawings.
Fig. 1 is the structural schematic diagram of the utility model reinforced nylon retainer.
Fig. 2 is the cross-sectional view of the utility model reinforced nylon retainer.
Fig. 3 is A-A schematic diagram in Fig. 2.
Fig. 4 is that steel ball is assembled to the schematic diagram in the ball pocket hole of the utility model reinforced nylon retainer.
Specific embodiment
In order to be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, under
The utility model is further described in face.
Referring to Fig. 1 to Fig. 3, a kind of reinforced nylon retainer shown in figure, including using ring made of nylon material
Shape keeps frame body 10, if dry bulb pocket hole 20 has been uniformly arranged on the cyclic annular circumferencial direction for keeping frame body 10, in adjacent ball pocket hole
Reinforcing rib 30 is provided on the cyclic annular outer circumference surface 11 for keeping frame body 10 between 20.In addition to promoting the whole strong of retainer
Degree, the cyclic annular wall thickness for keeping frame body 10 of the utility model are also thicker than the retainer of transmission.By increasing cyclic annular holding frame body 10
Wall thickness and the cyclic annular outer circumference surface 11 for keeping frame body 10 between adjacent ball pocket hole 20 on be provided with reinforcing rib 30, improve
The intensity of entire reinforced nylon retainer.
Steel ball 40 slides from the cyclic annular ball pocket hole 20 for keeping frame body 10 in order to prevent, and retainer is made to be resistant to high revolving speed, resistance to
Top load extends the service life of bearing.The utility model is provided with fore shaft 21 in each ball pocket hole 20, fore shaft 21 it is straight
Diameter d1 is less than or equal to 0.97 times of 40 diameter DW of steel ball, so that the self-locking steel ball 40 of fore shaft 21, prevents steel ball 40 sliding from ball pocket hole 20
It drops out and.
The basic principles and main features of the present invention and the advantages of the present invention have been shown and described above.Current row
The technical staff of industry is described in above embodiments and description it should be appreciated that the present utility model is not limited to the above embodiments
Only illustrate the principles of the present invention, on the premise of not departing from the spirit and scope of the utility model, the utility model is also
It will have various changes and improvements, these various changes and improvements fall within the scope of the claimed invention.The utility model
Claimed range is defined by the appending claims and its equivalent thereof.
