Description

Technical Field

[0001] This utility model relates to the field of game console motor technology, specifically a motor bearing for game consoles. Background Technology

[0002] Bearings are an important component in modern mechanical equipment. Their main function is to support rotating mechanical bodies, reduce the coefficient of friction during their movement, and ensure their rotational accuracy. According to the different frictional properties of moving elements, bearings can be divided into two main categories: rolling bearings and sliding bearings. Game machine motors also require bearings when they are working. In order to meet the needs of the market, a motor bearing for game machines is needed.

[0003] Existing motor bearings have poor wear resistance and short service life. Their sealing and oil leakage prevention effects are also inadequate, easily leading to oil seepage between the bearing body and the retaining ring during operation. Furthermore, existing motor bearings typically lack clearance reduction capabilities, making the motor shaft prone to loosening between itself and the inner ring, significantly reducing the precision of the motor shaft installation within the bearing body and inner ring. In addition, existing motor bearings are inconvenient to lubricate, resulting in reduced lubrication and increased noise during operation. Utility Model Content

[0004] The purpose of this utility model is to provide a motor bearing for game consoles, in order to solve the problems mentioned in the background art, such as insufficient sealing and oil leakage prevention effect of motor bearings, lack of function to reduce gaps, and inconvenience in oiling.

[0006] Preferably, the bearing body has an outer chamfer at its top end, the chamfer specification of which is C0.2; the inner ring has a top chamfer at its top end, the chamfer specification of which is C0.2; the bearing body has a bottom chamfer at its bottom end, the chamfer specification of which is C0.3; the bearing body has a middle chamfer on its surface, the chamfer specification of which is R0.3; the inner ring has a surface chamfer on its surface, the chamfer specification of which is R0.3; and a dust cover is provided on the surface of the bearing body, the dust cover being detachably connected to the surface of the bearing body.

[0007] Preferably, the gap reduction mechanism consists of a washer, a stud, a fixing member, and a screw hole. The surface of the inner ring is equipped with a fixing member, and both the fixing member and the inner wall of the inner ring are provided with screw holes. The surface of the fixing member is threaded with a stud, and one end of the stud passes through the fixing member and the inner ring in sequence and is threadedly fastened to the surface of the motor shaft.

[0008] Preferably, the inner wall of the inner ring is fitted with a gasket to reduce the gap between the inner ring and the motor shaft, and the inner wall of the gasket is in contact with the surface of the motor shaft.

[0009] Preferably, the sealing and oil-proof mechanism consists of a positioning clip, a positioning groove, a first silicone pad, and a second silicone pad. The surface of the limiting ring is equipped with positioning clips, and the inner wall of the bearing body is provided with positioning grooves. The positioning grooves and the surfaces of the positioning clips engage with each other.

[0010] Preferably, the surfaces of the limiting rings are all adhered with a second silicone pad, and the inner walls of the bearing body are all adhered with a first silicone pad, with the surfaces of the first silicone pad and the second silicone pad in contact.

[0011] Preferably, the convenient lubrication mechanism consists of a sealing plug, a handle, a first rubber pad, and a second rubber pad. The surface of the bearing body is provided with a sealing plug, one end of which extends into the interior of the lubrication hole, and a handle is installed on the surface of the sealing plug.

[0012] Preferably, the surface of the sealing plug is covered with a second rubber gasket for sealing between the oil filling hole and the sealing plug, the surface of the second rubber gasket is covered with a first rubber gasket, and the surface of the first rubber gasket is in contact with the inner wall of the bearing body.

[0013] Compared with the prior art, the beneficial effects of this utility model are: the motor bearing for the game machine not only enables the sealing treatment between the bearing body and the limiting ring during the use of the motor bearing, avoiding the phenomenon of oil seepage from the bearing body and the limiting ring during the use of the motor bearing, and preventing the motor shaft from loosening between the inner ring during the use of the motor bearing, but also greatly improves the accuracy of the motor shaft when installed inside the bearing body and the inner ring, and makes it convenient for the user to lubricate the surface of the ball bearing during the use of the motor bearing, resulting in better lubrication effect during the use of the motor bearing and reducing the noise of the motor bearing during operation;

[0014] 1. By setting a sealing and oil leakage prevention mechanism, the limiting ring drives the positioning clip to automatically lock into the corresponding positioning slot, so that the limiting ring can be stably installed on the surface of the bearing body and the inner ring. At this time, the limiting ring drives the second silicone pad to move to contact the surface of the second silicone pad. Under the joint action of the first silicone pad and the second silicone pad, the limiting ring, the bearing body and the inner ring are sealed, preventing the oil on the surface of the ball from seeping out through the gap between the bearing body, the inner ring and the limiting ring. This makes the overall sealing performance of the motor bearing higher and realizes the function of sealing and preventing oil leakage of the motor bearing. Thus, the motor bearing can be sealed between the bearing body and the limiting ring during use, avoiding the phenomenon of oil seeping out from between the bearing body and the limiting ring during the use of the motor bearing.

[0015] 2. By incorporating a clearance-reducing mechanism, the user places the bearing body on the surface of the motor shaft, allowing one end of the motor shaft to pass through the central hole and extend to the outside of the central hole. At this time, the gasket on the inner wall of the inner ring moves to fit against the surface of the motor shaft. The user then tightens the studs on the surface of the inner ring, causing the studs to rotate on the surface of the fixing component. With the threaded engagement between the studs and the threaded holes, the inner ring and the bearing body are stably installed on the surface of the motor shaft. By adjusting the studs, the installation of the bearing body and the inner ring on the surface of the motor shaft becomes more precise, achieving the function of reducing the clearance of the motor bearing. This prevents loosening between the motor shaft and the inner ring during use and greatly improves the accuracy of the motor shaft when installed inside the bearing body and the inner ring.

[0016] 3. By incorporating a convenient lubrication mechanism, the user pulls the handle on the bearing body surface, causing the handle to move the sealing plug. This causes the sealing plug to move the second and first rubber pads, moving the first rubber pad away from the inner wall of the lubrication hole. The sealing plug can then be removed from the bearing body and the lubrication hole surface. The user can then inject lubricating oil into the ball bearing surface through the lubrication hole and return the sealing plug to its original position. The combined action of the first and second rubber pads prevents the sealing plug from loosening from the lubrication hole surface, thus enabling convenient lubrication of the motor bearing. This allows users to easily lubricate the ball bearing surface during operation, resulting in better lubrication and reduced noise during motor bearing operation. Attached Figure Description

[0025] The present invention provides a structure for a motor bearing used in a game console, as shown in the following figure. Figure 1 and Figure 2 As shown, the bearing includes a bearing body 1. An inner ring 101 is provided inside the bearing body 1, and the inner ring 101 rotates with the inner wall of the bearing body 1. A central hole 102, penetrating from both ends, is opened at the center of the inner ring 101. A motor shaft 111 is disposed inside the central hole 102, with both ends extending to the outer sides of the central hole 102. An outer chamfer 103 with a chamfer specification of C0.2 is opened at the top of the bearing body 1. A top chamfer 105 with a chamfer specification of C0.2 is opened at the top of the inner ring 101. A bottom chamfer 104 with a chamfer specification of C0.3 is opened at the bottom of the bearing body 1. The bearing body 1 has a central chamfer 106 on its surface, with a chamfer size of R0.3. The inner ring 101 has a surface chamfer 107 on its surface, with a chamfer size of R0.3. The bearing body 1 has a dust cover 108 on its surface, which is detachably connected to the surface of the bearing body 1. The bearing body 1 has equally spaced balls 110 inside, which rotate in relation to the inner wall of the bearing body 1 and the surface of the inner ring 101. The bearing body 1 has a limiting ring 109 inside for limiting the movement of the balls 110. The bearing body 1 has an oil filling hole 112 on its surface, which is connected to the interior of the bearing body 1.

[0026] Furthermore, such as Figure 3 and Figure 4As shown, the bearing body 1 and the inner ring 101 are provided with a gap reduction mechanism 2. The gap reduction mechanism 2 consists of a washer 21, a stud 22, a fastener 23 and a screw hole 24. The surface of the inner ring 101 is equipped with a fastener 23. The fastener 23 and the inner wall of the inner ring 101 are provided with screw holes 24. The surface of the fastener 23 is threaded with a stud 22. One end of the stud 22 passes through the fastener 23 and the inner ring 101 in sequence and is threadedly fastened to the surface of the motor shaft 111. The inner wall of the inner ring 101 is equipped with a washer 21 for reducing the gap between the inner ring 101 and the motor shaft 111. The inner wall of the washer 21 is in contact with the surface of the motor shaft 111.

[0027] During implementation, the gasket 21 on the inner wall of the inner ring 101 moves to fit against the surface of the motor shaft 111. The user then tightens the studs 22 on the surface of the inner ring 101, causing the studs 22 to rotate on the surface of the fixing member 23. With the threaded engagement of the studs 22 and the screw hole 24, the inner ring 101 and the bearing body 1 are stably installed on the surface of the motor shaft 111. By adjusting the studs 22, the installation of the bearing body 1 and the inner ring 101 on the surface of the motor shaft 111 is made more precise, thereby achieving the function of reducing the clearance of the motor bearing.

[0028] Furthermore, such as Figure 3 and Figure 5 As shown, a sealing and oil-proof mechanism 3 is provided on the inner wall of the bearing body 1 and the surface of the limiting ring 109. The sealing and oil-proof mechanism 3 consists of a positioning clip 31, a positioning groove 32, a first silicone pad 33, and a second silicone pad 34. The surface of the limiting ring 109 is equipped with a positioning clip 31, and the inner wall of the bearing body 1 is provided with a positioning groove 32. The positioning groove 32 and the surface of the positioning clip 31 are engaged with each other. The surface of the limiting ring 109 is adhered with a second silicone pad 34, and the inner wall of the bearing body 1 is adhered with a first silicone pad 33. The surfaces of the first silicone pad 33 and the second silicone pad 34 are in contact.

[0029] During implementation, the limiting ring 109 drives the positioning clip 31 to automatically engage with the corresponding positioning slot 32, allowing the limiting ring 109 to be stably installed on the surfaces of the bearing body 1 and the inner ring 101. At this time, the limiting ring 109 drives the second silicone pad 34 to move to contact the surface of the second silicone pad 34. Under the combined action of the first silicone pad 33 and the second silicone pad 34, a sealing treatment is performed between the limiting ring 109, the bearing body 1, and the inner ring 101, preventing oil on the surface of the ball 110 from seeping out through the gap between the bearing body 1, the inner ring 101, and the limiting ring 109, thus improving the overall sealing performance of the motor bearing and achieving the function of sealing and preventing oil leakage in the motor bearing.

[0030] Furthermore, such as Figure 3 and Figure 6As shown, the bearing body 1 and the surface of the oil filling hole 112 are provided with a convenient oiling mechanism 4. The convenient oiling mechanism 4 is composed of a sealing plug 41, a handle 42, a first rubber gasket 43 and a second rubber gasket 44. The surface of the bearing body 1 is provided with a sealing plug 41, one end of which extends into the interior of the oil filling hole 112. The surface of the sealing plug 41 is equipped with a handle 42. The surface of the sealing plug 41 is covered with a second rubber gasket 44 for sealing between the oil filling hole 112 and the sealing plug 41. The surface of the second rubber gasket 44 is covered with the first rubber gasket 43. The surface of the first rubber gasket 43 is in contact with the inner wall of the bearing body 1.

[0031] In practice, the user pulls the handle 42 on the surface of the bearing body 1, causing the handle 42 to move the sealing plug 41. At this time, the sealing plug 41 moves the second rubber pad 44 and the first rubber pad 43, causing the first rubber pad 43 to move away from the inner wall of the oil filling hole 112, and remove the sealing plug 41 from the surface of the bearing body 1 and the oil filling hole 112. The user injects lubricating oil into the surface of the ball 110 through the oil filling hole 112, and then resets the sealing plug 41. Under the combined action of the first rubber pad 43 and the second rubber pad 44, the sealing plug 41 is prevented from falling off the surface of the oil filling hole 112, so as to realize the function of convenient oiling of the motor bearing.

[0032] Working principle: In use, first place the bearing body 1 in the designated position. Under the action of the limiting ring 109, the gap between the balls 110 is fixed to prevent the balls 110 from colliding with each other at the designated time. The user installs the limiting ring 109 on the surfaces of the bearing body 1 and the inner ring 101 on both sides to limit the balls 110 and prevent collision. Then, the dust cover 108 is installed on the surfaces of the bearing body 1 and the inner ring 101 on both sides to prevent dust between the bearing body 1 and the inner ring 101. At this time, the limiting ring 109 drives the positioning clip 31 to automatically lock into the corresponding positioning slot 32, so that the limiting ring 109 can be stably installed on the bearing body 1 and the inner ring. At this time, the limiting ring 109 drives the second silicone pad 34 to contact the surface of the second silicone pad 34. Under the joint action of the first silicone pad 33 and the second silicone pad 34, the limiting ring 109, the bearing body 1 and the inner ring 101 are sealed to prevent the oil on the surface of the ball 110 from seeping out through the gap between the bearing body 1, the inner ring 101 and the limiting ring 109. This makes the overall sealing performance of the motor bearing higher, so as to realize the function of sealing and preventing oil leakage of the motor bearing. Thus, when the motor bearing is used, it can seal the bearing body 1 and the limiting ring 109, and prevent the phenomenon of oil seeping out from the bearing body 1 and the limiting ring 109 during the use of the motor bearing.

[0033] Subsequently, the user places the bearing body 1 on the surface of the motor shaft 111, so that one end of the motor shaft 111 passes through the central hole 102 and extends to the outside of the central hole 102. At this time, the gasket 21 on the inner wall of the inner ring 101 moves to fit against the surface of the motor shaft 111. The user then tightens the studs 22 on the surface of the inner ring 101, so that the studs 22 rotate on the surface of the fixing part 23. With the threaded engagement of the studs 22 and the screw hole 24, the inner ring 101 and the bearing body 1 are stably installed on the surface of the motor shaft 111. By adjusting the studs 22, the installation of the bearing body 1 and the inner ring 101 on the surface of the motor shaft 111 is more precise, so as to realize the function of reducing the clearance of the motor bearing. This prevents the motor shaft 111 from loosening when in use, and greatly improves the accuracy of the motor shaft 111 when installed inside the bearing body 1 and the inner ring 101.

[0034] Subsequently, if the surface of the ball bearing 110 lacks oil, it will cause the ball bearing 110 to jam when rotating on the inner wall of the bearing body 1. The user pulls the handle 42 on the surface of the bearing body 1, causing the handle 42 to move the sealing plug 41. At this time, the sealing plug 41 moves the second rubber pad 44 and the first rubber pad 43, causing the first rubber pad 43 to move away from the inner wall of the oiling hole 112, and remove the sealing plug 41 from the surface of the bearing body 1 and the oiling hole 112. The user injects lubricating oil into the surface of the ball bearing 110 through the oiling hole 112, and then resets the sealing plug 41. Under the combined action of the first rubber pad 43 and the second rubber pad 44, the sealing plug 41 is prevented from falling off the surface of the oiling hole 112, so as to realize the function of convenient oiling of the motor bearing. This makes it convenient for the user to oil the surface of the ball bearing 110 when using the motor bearing, so as to improve the lubrication effect of the motor bearing during use, reduce the noise of the motor bearing during operation, and finally complete the use of the motor bearing.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
