Abstract
A kind of ball with internal spiral oil guide slot of the utility model, it comprises ball body, and the internal surface of described ball body is uniformly distributed multiple internal spiral oil guide slot, and described ball body upper end has annulus, and described internal spiral oil guide slot is communicated with annulus; The helix angle of described internal spiral oil guide slot is 30 °; The radius of described internal spiral oil guide slot is 0.2 ~ 0.25mm.The utility model structure is simple, and it is convenient to manufacture, and is beneficial to long-run development and expands Applicable scope; Internal spiral oil guide slot is provided with at the internal surface of ball body, can lubricant oil be stored, when ball body internal surface contacts with spider external cylindrical surface, the lubrication effect of ball body and spider can be strengthened, thus reduce the wearing and tearing of ball sphere, improve the working life of ball body.
Description
Technical field
The utility model relates to a kind of ball, is specifically related to a kind of ball with internal spiral oil guide slot.
Background technique
Three ball pin balls of the prior art, inner cylindrical surface is continuous whole garden, Shortcomings on vibrational power flow, and its inner cylindrical surface, in the spider cylinder contact friction of universal joint three ball pin ball and three ball pins, greatly reduces the working life of universal joint, is unfavorable for long-run development.Such ball also could meet the demand of existing market, haves much room for improvement!
Model utility content
Technical problem to be solved in the utility model is to provide a kind of ball with internal spiral oil guide slot, and not only structure is simply exquisite for it, and can improve working life, can expand Applicable scope simultaneously.
Technical problem to be solved in the utility model is taked following technological scheme to realize:
With a ball for internal spiral oil guide slot, it comprises ball body, and the internal surface of described ball body is uniformly distributed multiple internal spiral oil guide slot, and described ball body upper end has annulus, and described internal spiral oil guide slot is communicated with annulus.
The helix angle of described internal spiral oil guide slot is 30 °.
The radius of described internal spiral oil guide slot is 0.2 ~ 0.25mm.
The beneficial effects of the utility model are: the utility model structure is simple, and it is convenient to manufacture, and are beneficial to long-run development and expand Applicable scope; Internal spiral oil guide slot is provided with at the internal surface of ball body, can lubricant oil be stored, when ball body internal surface contacts with spider external cylindrical surface, the lubrication effect of ball body and spider can be strengthened, thus reduce the wearing and tearing of ball sphere, improve the working life of ball body; Ball body upper end has the annulus communicated with internal spiral oil guide slot, is convenient to the interpolation of lubricant oil.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;
Fig. 2 is A_A sectional view.
In figure: ball body 1, annulus 2, internal spiral oil guide slot 3.
Embodiment
In order to technological means of the present utility model, creation characteristic, reach object and effect is easy to understand, below in conjunction with concrete diagram, set forth the utility model further.
As shown in Figure 1-2, a kind of ball with internal spiral oil guide slot, it comprises ball body 1, and the internal surface of ball body 1 is uniformly distributed multiple internal spiral oil guide slot 3, and ball body 1 upper end has annulus 2, and internal spiral oil guide slot 3 is communicated with annulus 2.
The helix angle of internal spiral oil guide slot 3 is 30 °.
The radius of internal spiral oil guide slot 3 is 0.2 ~ 0.25mm.
Internal spiral oil guide slot 3 is provided with at the internal surface of ball body 1, can lubricant oil be stored, when ball body 1 internal surface contacts with spider external cylindrical surface, the lubrication effect of ball body 1 and spider can be strengthened, thus reduce the wearing and tearing of ball sphere, improve the working life of ball body 1; Ball body 1 upper end has the annulus 2 communicated with internal spiral oil guide slot 3, is convenient to the interpolation of lubricant oil.
More than show and describe basic principle of the present utility model and 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; 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.
