Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a lubricating oil-filling type bearing. Background Art

[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Modern linear motion bearings use the same working principle, but sometimes balls are used instead of rollers. The simplest rotary bearing is the sleeve bearing, which is just a bushing sandwiched between the wheel and the axle. This design was later replaced by rolling bearings, which replace the original bushing with many cylindrical rollers, and each rolling body is like a separate wheel.

[0003] Most of the existing bearing devices are used in dusty environments. Although a dust cover can prevent dust from easily entering the bearing seat cavity and causing the bearing to be contaminated and prone to failure, the dust cover will make it difficult to discharge the heat generated by the rotation of the bearing, thereby affecting the lubricity of the bearing. Therefore, we propose a lubricating oil-filled bearing to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that most of the prior art are used in dusty environments. Although a dust cover can prevent dust from easily entering the accommodating cavity of the bearing seat, which makes the bearing contaminated and prone to failure, the dust cover will make it difficult to discharge the heat generated by the rotation of the bearing, thereby affecting the lubricity of the bearing. A lubricating oil-filled bearing is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions: a lubricating oil-filling bearing, comprising an integral structure and an auxiliary structure, wherein the auxiliary structure is located at both sides of the top of the integral structure;

[0006] The overall structure includes a bearing body, the front and rear outer surfaces of the bearing body are provided with sealing grooves, the inner surface wall of the sealing groove is fixedly connected with a sealing ring, the outer surface of the sealing ring is fixedly connected with a dust cover, the outer surface of the dust cover is fixedly connected with a plurality of evenly distributed heat sinks, the outer surface of the sealing ring is penetrated by a plurality of evenly distributed round tubes, a filter is fixedly connected at the center of the outer surface of the round tube, and the inner surface of the bearing body is fixedly connected with a plurality of evenly distributed support members.

[0007] Preferably, the inner surface of the support member is provided with a plurality of evenly distributed rolling bodies.

[0008] Preferably, a fixing piece is fixedly connected to the outer surface of the supporting piece.

[0009] Preferably, the outer surface of the fixing member is fixedly connected to the inner ring of the bearing.

[0010] Preferably, a transition portion is provided on the outer surface of the support member.

[0011] Preferably, the auxiliary structure comprises a round rod, a sealing cover is fixedly connected to the top end surface of the round rod, and an outer surface of the round rod is slidably connected to an inner surface of the transition portion.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, when in use, the dust cover is located in the front and rear positions of the bearing body, so through the cooperation of the heat sink, the surface heat dissipation area can be increased, which helps the bearing body to dissipate heat quickly, and through the cooperation of the round tube and the filter screen, the effect of reversing ventilation can be achieved, and the air enters the interior of the bearing body through the round tube and flows through the bearing body, so as to increase the heat dissipation effect.

[0014] 2. In the utility model, before the air enters the round tube, it will first be filtered through the filter net, so that the air can be filtered to prevent dust from entering the bearing body together with the air, thereby ensuring that the bearing body can operate normally and extending its service life. The transition part can be used as an oil channel, so after oil is injected into the transition part, it can be transported to the surface of multiple rolling elements to provide lubrication for the rolling elements.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0021] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0022] Embodiment 1, as Figure 1-Figure 4 As shown, a lubricating oil-filling type bearing includes an overall structure 1 and an auxiliary structure 2, wherein the auxiliary structure 2 is located at both sides of the top of the overall structure 1; the overall structure 1 includes a bearing body 101, and sealing grooves 103 are provided on the front and rear outer surfaces of the bearing body 101, and a sealing ring 102 is fixedly connected to the inner surface wall of the sealing groove 103, and a dust cover 111 is fixedly connected to the outer surface of the sealing ring 102, and a plurality of evenly distributed heat sinks 112 are fixedly connected to the outer surface of the dust cover 111, and a plurality of evenly distributed round tubes 110 are penetrated through the outer surface of the sealing ring 102, and a filter screen 109 is fixedly connected at the center of the outer surface of the round tube 110, and a plurality of evenly distributed support members 107 are fixedly connected to the inner surface of the bearing body 101.

[0023] The effect achieved by the entire embodiment 1 is that, through the setting of the sealing groove 103 and the sealing ring 102, the sealing performance of the connection between the dust cover 111 and the bearing body 101 can be increased, so as to prevent external dust from entering the bearing body 101 through the connection, thereby playing a protective role. The material of the sealing ring 102 is composed of fluororubber, which has excellent sealing requirements of high temperature resistance, oil resistance and wear resistance. Through the setting of the heat sink 112, the surface heat dissipation area can be increased. Through the setting of the circular tube 110, the external air can enter and flow through the bearing body 101, so as to increase the heat dissipation effect. The setting of the filter 109 can filter the air entering the circular tube 110 to prevent dust in the air from entering the bearing body 101, so as to ensure that the bearing body 101 can operate normally.

[0024] Embodiment 2, as Figure 1-Figure 4As shown, the inner surface of the support member 107 is provided with a plurality of evenly distributed rolling elements 106, the outer surface of the support member 107 is fixedly connected with the fixing member 105, the outer surface of the fixing member 105 is fixedly connected with the bearing inner ring 104, the outer surface of the support member 107 is provided with a transition portion 108, the auxiliary structure 2 includes a round rod 201, the top end surface of the round rod 201 is fixedly connected with a sealing cover 202, and the outer surface of the round rod 201 is slidably connected to the inner surface of the transition portion 108.

[0025] The effect achieved by the entire embodiment 2 is that, when in use, the user can inject oil into the transition part 108, and then through the cooperation of the fixing member 105, the support member 107 and the transition part 108, lubrication can be provided for the rolling element 106, thereby avoiding waste caused by excessive dripping of lubricating oil due to directly dripping lubricating oil onto the rolling element 106. Through the arrangement of the round rod 201 and the sealing cover 202, when oil injection is not required, the transition part 108 can be sealed to prevent external dust from entering the transition part 108.

[0026] Working principle: First, in the actual use process, such as Figure 1 and Figure 4 As shown, the dust cover 111 is arranged at the front and rear positions of the bearing body 101, and a plurality of heat sinks 112 are arranged. Then, through the cooperation of the heat sink 112, a sufficiently large heat dissipation area can be increased, and the external air can enter through the circular tube 110 and flow through the bearing body 101, so the heat dissipation effect can be improved. Before the air enters, it will first be filtered by the filter 109 before it can enter the circular tube 110. Then, the setting of the filter 109 can filter the dust in the air to prevent the dust from entering together. The bearing body 101 can ensure the normal operation of the bearing body 101 and extend the service life of the bearing body 101. When lubricating oil needs to be added, the user can first take out the round tube 110 and the sealing cover 202, and then fill the transition part 108 with oil. The lubricating oil is then transported through the transition part 108 and eventually transported to each rolling element 106, thereby providing lubrication for the rolling element 106 and avoiding the waste caused by excessive dripping of lubricating oil due to directly dripping lubricating oil onto the rolling element 106.

[0027] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
