Background technique
Thrust bearing is usually to be made of two thrust washers or more and several rolling elements, general thrust pad Piece is divided into axis piece and seat piece, the generally most common pattern of rolling element be combined by irony or copper holder it is integral.Such profile shaft Holding most common is steel-ball type thrust bearing.The design and use of thrust bearing are to bear axial load.It is rolled with other thrusts Sub- bearing is compared, and steel-ball type thrust bearing friction factor is lower, and revolving speed is higher, and has aligning performance.
Compared with the common roller bearing with bearing inner race, bearing outer ring, thrust ball bearing is not resided on axis and is used When, a confined space easy to form in the inner ring of thrust washer, the middle part heat of thrust washer is difficult to when bearing long-play It distributes, will affect bearing life and greasy property, therefore, the heat dissipation of the higher thrust ball bearing of revolving speed is particularly important.
Utility model content
A kind of thrust washer progress the purpose of the utility model is to provide air-flow generated using bearing rotation to bearing The thrust ball bearing of heat dissipation.
To achieve the goals above, the utility model provides a kind of thrust ball bearing for being easy to radiate, including two set relatively The annular thrust washer and the rolling element between two thrust washers set, the thrust washer has to be extended radially End face towards rolling element and the annular side that extends in the axial direction, wherein the end face, which can be divided into, is located at centre Roller surface for accommodating rolling element and be located at the roller surface two sides and protrude from the edge surface of the roller surface, The junction of the end face and the side be arranged groove, for the thrust washer rotation when by air-flow introduce described in push away Power ball bearing.
Preferably, the groove has the first plane and the second plane, and the expanding surface of first plane passes through The rotation axis of the thrust washer, second plane obliquely intersect with first plane.
Preferably, the quantity of the groove, position, shape, size, depth can be according to applied thrusts The size of ball bearing and be changed.
Preferably, the groove is less than the width of the edge surface in the depth radially of the thrust washer Degree.
Preferably, the groove is in cone-shaped, the tip direction roller surface of cone.
Preferably, in the multiple grooves of evenly over the circumference distribution of the thrust washer.
The utility model provide it is a kind of be easy to radiate thrust ball bearing, including two thrust washers and be set to thrust washer side Air-flow is led to by the gap location among two thrust washers by groove, compared to traditional thrust in rotation along upper groove Ball bearing is not arranged in shaft in use, can be improved the mobility of thrust washer hollow cavity, so that bearing is turning in bearing Can all have fine supplementary function by airflow radiating in dynamic to bearing thrust washer and lubricating oil cooling, improve bearing Service life.

Specific embodiment
With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is not intended to limit the scope of the present invention for illustrating the utility model.
As depicted in figs. 1 and 2, a kind of thrust ball bearing for being easy to radiate of the preferred embodiment in the utility model comprising Thrust washer and the rolling element between two thrust washers, thrust bearing are usually to use as transmitting bearing load, axis Pressure to load is generally large and pressure amplitude is also larger.In practice, thrust ball bearing can be socketed in shaft Using or be directly installed on two pedestals and used without being threaded through in shaft, be not threaded through in shaft in use, two thrusts Gap location between washer is easy to produce a relatively closed cavity, and heat is assembled in this cavity, so that the use of bearing Service life, greasy property are all by the raised influence of temperature.
Based on the above-mentioned technical proposal, a kind of thrust ball bearing for being easy to radiate is provided in the present embodiment, including two set relatively The annular thrust washer 10 and the rolling element 20 between two thrust washers 10 set, wherein thrust washer 10 is this bearing Support construction for bearing load, accommodates rolling element 20, and rolling element 20 can be ball roller.
Specifically, as shown in Figure 1, thrust washer 10 have extend radially towards the end face of rolling element 20 30 and The annular side 40 that axis upwardly extends, wherein end face 30 can be divided into the rolling being located in the middle for accommodating rolling element 20 Road face 31 and edge surface 32 that is being located at 31 two sides of roller surface and protruding from roller surface 31, when thrust washer 10 rotates, rolling Kinetoplast 20 comes the space in space and lateral wall at the inner sidewall of thrust washer 10 is mutually isolated, does not wear in thrust ball bearing It is located in shaft in use, the end of thrust ball bearing needs to be fixed in pedestal, this results in the inner sidewall of thrust washer 10 Heat is easy to concentrate at the space at place, so that the using effect of bearing is easier to increase.
In order to which heat distributes at the space at the inner sidewall to thrust washer 10, by end face 30 and side 40 Groove 33 is arranged in junction, and groove 33 is used to that air-flow is introduced thrust ball bearing when thrust washer 10 rotates, air-flow is drawn At space to the inner sidewall of thrust washer 10, also there is good booster action to the lubricating oil cooling of bearing.
Preferably, as shown in Fig. 2, groove 33 has the first plane 34 and the second plane 35, the expanding surface of the first plane 34 By the rotation axis of thrust washer 10, the second plane 35 obliquely intersects with the first plane 34, and the second plane 35 can be by gas Stream is led in groove 33, the first plane 34 be used for air carry out enclosing so that air-flow along groove 33 to bearing thrust pad Gap location flowing between circle 10, or turbulent flow is generated, the mobility of air is improved, so that the thrust washer of thrust ball bearing exists In rotation cooling rate can be greatly improved by air-flow.
Preferably, the quantity of groove 33, position, shape, size, depth can be according to applied thrust ball bearings Size and be changed, the size of thrust ball bearing is bigger, and the size of groove 33 correspondingly increases.
Preferably, groove 33 is less than the width of edge surface 32 in the depth radially of thrust washer 10, so that groove 33 The intensity of thrust washer 10 will not be reduced, can guarantee the service performance of thrust washer 10.
Preferably, groove 33 is in cone-shaped, the tip direction roller surface 31 of cone, so that groove 33 is easy to process, direction The cone-shaped groove 33 of roller surface 31 can guide air-flow into roller surface 31, improve the radiating efficiency of the roller surface 31 of bearing.
Preferably, in the multiple grooves 33 of the evenly over the circumference distribution of thrust washer 10, so that heat dissipation effect is more uniform.
To sum up, the utility model embodiment provides a kind of thrust ball bearing for being easy to radiate, including thrust washer and is set to Groove on thrust washer, the cone-shaped groove by being directed toward roller surface can guide air-flow in roller surface into, can be improved axis The radiating efficiency held improves the service life of bearing.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art For art personnel, without deviating from the technical principle of the utility model, several improvement and replacement can also be made, these change It also should be regarded as the protection scope of the utility model into replacement.
