Description

Technical Field

[0001] This utility model relates to the field of bearing stamping cage technology, specifically a stamping cage for tapered roller bearings. Background Technology

[0002] A cage (also known as a bearing retainer) is a bearing component that partially encloses all or part of the rolling elements and moves with them. It is used to isolate the rolling elements and usually also guides and holds them within the bearing.

[0003] The existing cage has a large contact area between the pocket and the bearing roller, which makes it easy for the bearing roller to rub against the cage during rotation, leading to cage wear. In addition, the narrow internal space of the bearing makes it inconvenient for users to add oil, affecting the final lubrication effect and causing lubricant waste. Therefore, it is necessary to improve the tapered roller bearing stamped cage to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a stamped cage for tapered roller bearings to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stamped cage for tapered roller bearings, comprising a cage body, a fixing mechanism inside the cage body, and an oil injection mechanism inside the cage body.

[0006] Preferably, the fixing mechanism includes a spring, which is fixedly installed inside the cage body. A sliding sleeve is fixedly installed at the end of the spring away from the cage body. An arc-shaped clamping block is fixedly installed inside the sliding sleeve. A ball bearing is rotatably installed inside the arc-shaped clamping block. A placement groove is provided on the outside of the cage body, which realizes the rapid positioning and installation of multiple roller bodies.

[0007] Preferably, the sliding sleeve is slidably installed inside the cage body, and the arc-shaped clamping block and the ball are disposed inside the placement groove. The ball contacts the roller body, thereby reducing friction during the operation of the roller.

[0008] Preferably, the oiling mechanism includes an oiling groove, which is disposed inside the cage body. A fixing frame is fixedly installed inside the oiling groove. A second spring is fixedly installed on the top of the fixing frame. A rubber plug is fixedly installed on the top of the second spring. A connecting rod is fixedly installed on the bottom of the rubber plug. An oiling hole is provided at the bottom of the oiling groove. This solves the problem that after the existing cage body is assembled, the internal space of the bearing is narrow, making it inconvenient for the user to lubricate the inside.

[0009] Preferably, the retainer body has an oil filling hole at the position corresponding to the rubber plug, and the rubber plug is disposed inside the oil filling hole. The fixing bracket has a through hole at the position corresponding to the connecting rod, and the connecting rod is slidably installed inside the through hole. The rubber plug presses the connecting rod downward, thereby exposing the oil filling groove.

[0010] Preferably, the oil injection hole is located at the top of the placement groove, and lubricating oil enters the placement groove through the oil injection hole to lubricate the roller body.

[0011] Compared with the prior art, this utility model provides a stamped cage for tapered roller bearings, which has the following advantages:

[0012] 1. This stamped cage for tapered roller bearings, through a fixed mechanism, uses arc-shaped clamping blocks to clamp and fix the roller body during use. The contact between the balls and the roller body reduces friction during operation, improves bearing life, enables rapid positioning and installation of multiple roller bodies, prevents scattering during maintenance, and facilitates assembly and subsequent disassembly.

[0013] 2. The stamped cage of this tapered roller bearing, through the set oil injection mechanism, solves the problem that the internal space of the existing cage body is narrow after assembly, making it inconvenient for users to inject oil inside. The lubricating oil enters the placement groove through the oil injection hole to lubricate the roller body and also ensures the stability of the roller body during rotation.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0021] Example 1:

[0022] Please see Figure 1-2 This utility model provides a technical solution: a stamped cage for tapered roller bearings, including a cage body 1, a fixing mechanism 2 inside the cage body 1, and an oil injection mechanism 3 inside the cage body 1.

[0023] Furthermore, the fixing mechanism 2 includes a spring 21, which is fixedly installed inside the cage body 1. A sliding sleeve 22 is fixedly installed at the end of the spring 21 away from the cage body 1. An arc-shaped clamping block 23 is fixedly installed inside the sliding sleeve 22. A ball bearing 24 is rotatably installed inside the arc-shaped clamping block 23. A placement groove 25 is provided on the outside of the cage body 1, which realizes the rapid positioning and installation of multiple roller bodies.

[0024] Furthermore, the sliding sleeve 22 is slidably installed inside the cage body 1, and the arc-shaped clamping block 23 and the ball 24 are disposed inside the placement groove 25. The ball 24 contacts the roller body, thereby reducing the friction of the roller during operation.

[0025] Example 2:

[0026] Please see Figure 3Furthermore, in conjunction with Embodiment 1, it is further found that the oiling mechanism 3 includes an oiling groove 31, which is disposed inside the cage body 1. A fixing frame 32 is fixedly installed inside the oiling groove 31. A second spring 33 is fixedly installed on the top of the fixing frame 32. A rubber plug 34 is fixedly installed on the top of the second spring 33. A connecting rod 35 is fixedly installed on the bottom of the rubber plug 34. An oiling hole 36 is opened at the bottom of the oiling groove 31. This solves the problem that after the existing cage body 1 is assembled, the internal space of the bearing is narrow, making it inconvenient for the user to add oil to the inside.

[0027] Furthermore, the retainer body 1 has an oil filling hole at the corresponding position of the rubber plug 34, and the rubber plug 34 is placed inside the oil filling hole. The fixing bracket 32 ​​has a through hole at the corresponding position of the connecting rod 35, and the connecting rod 35 is slidably installed inside the through hole. The rubber plug 34 presses the connecting rod 35 downward, thereby exposing the oil filling groove 31.

[0028] Furthermore, an oil injection hole 36 is located at the top of the placement groove 25, through which lubricating oil enters the interior of the placement groove 25 to lubricate the roller body.

[0029] In actual operation, when this device is used, the roller body is placed inside the placement groove 25, and the arc-shaped clamping block 23 is pressed. The arc-shaped clamping block 23 presses the spring 21 through the sliding sleeve 22, thereby clamping and fixing the roller body. The roller ball 24 contacts the roller body, which reduces the friction of the roller during operation, improves the bearing life, and realizes the rapid positioning and installation of multiple roller bodies. It avoids scattering during maintenance, facilitates assembly and subsequent disassembly. When oiling is required, the oiling device is inserted into the rubber plug 34. The rubber plug 34 presses down on the connecting rod 35, thereby exposing the oiling groove 31. After the oil is injected into the oiling groove 31, the rubber plug 34 pushes up to block the oiling hole. This solves the problem that the internal space of the bearing is narrow after the existing cage body 1 is assembled, making it inconvenient for the user to add oil inside. The lubricating oil enters the placement groove 25 through the oiling hole 36 to lubricate the roller body and ensure the stability of the roller body during rotation.
