Abstract
The invention discloses a structure for an angular contact ball bearing retainer, which comprises a pocket hole (1) and an inner hole (2) for guiding a rolling element (5). A step hole (3) is arranged between the pocket hole (1) and the inner hole (2); an oil stop lug (4) is formed by the pocket hole (1), the inner hole (2) and the step hole (3); and an oil guiding cavity (6) is formed by the oil stop lug (4) and the rolling element (5). By using the designed structure, during the running process of the bearing, lubrication medium can well contact whole rolling surface so as to form excellent lubrication.
Description
Technical field
The present invention relates to a kind of retainer structure, particularly a kind of structure of angular contact ball bearing retainer that can improve lubricating condition.
Background technique
Bearing can not get good lubricating, and causes bearing corrosion, wearing and tearing to account for a very big part.Usually structure of angular contact ball bearing retainer is a simple circle annular, circumferencial direction several pocket holes that evenly distribute, shown in Figure 1 as Figure of description, in the bearing operation process, because the gap between the shoulder block of retainer endoporus and bearing is little, lubricant medium is difficult to enter retainer inside and bearing element surface, normal appearance causes bearing owing to insufficient lubrication in actual use the premature failure, destruction.
Summary of the invention
Technical problem to be solved by this invention is the premature damage that angular contact bearing causes owing to insufficient lubrication, thereby provides a kind of lubricant medium of being convenient to enter the bearing working position, makes the retainer structure of bearing operation under good lubricating status.
For reaching above-mentioned technique effect, technological scheme of the present invention is: a kind of structure of angular contact ball bearing retainer, comprise the pocket hole and the endoporus that are used to guide rolling element, between pocket hole and endoporus, be provided with step hole, pocket hole and endoporus, step hole intersect the oily projection of formation retaining, and rolling element forms the Oil Guide chamber with the oily projection of retaining.
In the bearing operation process, lubricant medium is because the interaction energy of the oily projection of retaining enters in the Oil Guide chamber very smoothly, and the Oil Guide function of utilizing the Oil Guide chamber to have is then along with rolling element enters whole rolling surface, form good lubricating circulatory system, thereby avoided the premature damage of bearing.
The invention has the beneficial effects as follows: structural design of the present invention makes bearing in operation process, and lubricant medium is very good to enter whole rolling surface, forms good lubrication, has reduced bearing vibration, noise and heating etc. simultaneously; Because design has the oily projection of retaining, also improved the intensity of retainer on the other hand, all be of value to the bearing assurance and the raising in working life.
Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is a retainer structural representation in the prior art.
Fig. 2 is a retainer structural representation of the present invention.
Fig. 3 is the local structure for amplifying schematic representation of retainer of the present invention.
Embodiment
Shown in Fig. 2,3, structure of angular contact ball bearing retainer, comprise the pocket hole 1 and the endoporus 2 that are used to guide rolling element 5, for solving the very difficult problem that fully enters the bearing element position of angular contact ball bearing lubricant medium in operation process, be provided with step hole 3 in pocket hole 1 and 2 of endoporus, the retaining oil projection 4 that forms is intersected with endoporus 2, step hole 3 in pocket hole 1, and rolling element 5 forms Oil Guide chamber 6 with the oily projection 4 of retaining.
Like this, in the bearing operation process, lubricant medium is owing to the interaction energy of the oily projection 4 of retaining enters in the Oil Guide chamber 6 very smoothly, then along with rolling element 5 enters whole rolling surface, form good lubricating circulatory system, lubricant medium can well enter whole rolling surface, forms good lubrication, has reduced bearing vibration, noise etc. simultaneously.
On the other hand,, also improved the intensity of retainer, be of value to the working life of bearing because design has the oily projection 4 of retaining.
The foregoing description does not limit the present invention in any way, and every employing is equal to replaces or technological scheme that the mode of equivalent transformation obtains all drops in protection scope of the present invention.
Claims (1)
1. structure of angular contact ball bearing retainer, comprise the pocket hole (1) and the endoporus (2) that are used to guide rolling element (5), it is characterized in that: between pocket hole (1) and endoporus (2), be provided with step hole (3), formation retaining oily projection (4) is intersected with endoporus (2), step hole (3) in pocket hole (1), and rolling element (5) forms Oil Guide chamber (6) with the oily projection of retaining (4).
