Abstract
A kind of semi-open thrust bearing the utility model relates to retainer with oil-through hole, including extrapolability piece, interior thrusting plate, the retainer being arranged between outer thrusting plate and interior thrusting plate and the rolling element being arranged in retainer, the retainer is circumferentially uniformly provided with several oil-through holes being connected to retainer inner cavity at outer diameter, and the outer diameter of the interior thrusting plate is less than diameter of a circle where each oil-through hole center.The retainer can make oil liquid more effectively lubricate internal retainer component with the semi-open thrust bearing of oil-through hole, bearing operation temperature is caused to increase the initial failure with bearing because of the package of thrusting plate during preventing bearing from running at high speed, so that being flowed into inside retainer faster into the oil in thrusting plate, reduce the friction between rolling element and retainer, it keeps bearing internal lubrication abundant, improve the bearing operation service life and reduces the temperature rise during bearing rotary.
Description
Technical field
A kind of semi-open thrust axis the utility model relates to technical field of bearings more particularly to retainer with oil-through hole
It holds.
Background technique
Existing thrust bearing as shown in Figure 1, include extrapolability piece 1 ', interior thrusting plate 2 ', retainer 3 ' and rolling element 4 ',
Such thrust bearing is easily worn after a longer time of use, to influence its service life.
Utility model content
The purpose of the utility model is to provide a kind of structures simple, lighter in weight, easy to assembly, holding with long service life
Semi-open thrust bearing of the frame with oil-through hole.
The utility model is achieved by the following technical solution: a kind of semi-open thrust axis of the retainer with oil-through hole
It holds, including extrapolability piece, interior thrusting plate, the retainer being arranged between outer thrusting plate and interior thrusting plate and is arranged in retainer
Rolling element, the retainer is circumferentially uniformly provided with several oil-through holes being connected to retainer inner cavity at the outer diameter, described
The outer diameter of interior thrusting plate is less than diameter of a circle where each oil-through hole center.
Sufficiently internal retainer component is lubricated for the ease of oil liquid, the oil-through hole runs through holding from top to bottom
Frame.
In order to avoid oil-through hole is excessive and retainer is caused in use process to deform or shake, the oil-through hole it is straight
Diameter is preferably less than the half of retainer width.
In order to avoid shake up and down occurs for rolling element, circle is straight where the outer diameter of the interior thrusting plate is greater than each rolling element
Diameter.
The beneficial effects of the utility model are:
1, the retainer of the utility model opens a circle oil-through hole at outer diameter, and interior thrusting plate outer diameter is decreased to expose oilhole,
Interior thrusting plate outer diameter is decreased to reveal oil-through hole, which can be applied to high speed (15000+rpm) rotation operating condition；
2, interior thrusting plate reduced diameter to oil-through hole exposes, and can make oil liquid to internal retainer component compared with conventional design
More effectively lubricated, cause during preventing bearing from running at high speed because of the package of thrusting plate bearing operation temperature increase and
The initial failure of bearing；
3, increase oilhole on retainer, so that flowing into inside retainer faster into the oil in thrusting plate, make rolling element
Friction between retainer reduces, and keeps Bearing inner (thrusting plate, retainer, rolling element) lubrication sufficiently, improves bearing fortune
Turn the service life and reduces the temperature rise during bearing rotary；
4, after using this design, in the case where meeting loading demands, it is effectively reduced product weight.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of thrust bearing in the prior art；
Fig. 2 is the retainer of the utility model with the structural schematic diagram of the semi-open thrust bearing of oil-through hole；
Fig. 3 is the partial enlargement diagram of part A in Fig. 2；
In figure, 1. extrapolability pieces, thrusting plate in 2., 3. retainers, 4. rolling elements, 5. oil-through holes.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be understood by those skilled in the art with feature, to make apparent specific boundary to the protection scope of the utility model
It is fixed.Direction term that the utility model is previously mentioned, such as "upper", "lower", "front", "rear", "left", "right", "top", "bottom" etc.,
It is only the direction with reference to annexed drawings.Therefore, the direction term used be to illustrate and understand the utility model, rather than to
Limit the utility model.
As shown in Fig. 2, a kind of semi-open thrust bearing of retainer with oil-through hole, including extrapolability piece 1, interior thrusting plate 2,
The rolling element 4 that the retainer 3 between outer thrusting plate 1 and interior thrusting plate 2 is arranged in and is arranged in retainer 3, interior thrusting plate 2 cover
Close on retainer 3, the retainer 3 be circumferentially uniformly provided at the outer diameter it is several be connected to 3 inner cavity of retainer it is excessively oily
The outer diameter in hole 5, the interior thrusting plate 2 is less than diameter of a circle where the center of each oil-through hole 5.
As shown in figure 3, the oil-through hole 5 runs through entire retainer 3 from top to bottom, the diameter of oil-through hole 5 is preferably less than
The half of 3 width of retainer, and the outer diameter of the interior thrusting plate 2 is greater than diameter of a circle where each 4 outermost end of rolling element, i.e., it is interior to push away
Power piece 2 still covers all rolling element, and oil-through hole 5 is not blocked by interior thrusting plate 2.
Above-described embodiments merely represent several embodiments of the utility model, the description thereof is more specific and detailed,
But it cannot be understood as the limitations to utility model patent range.It should be pointed out that for the common skill of this field
For art personnel, without departing from the concept of the premise utility, various modifications and improvements can be made, these are belonged to
The protection scope of the utility model.
