Description

Technical Field

[0001] This utility model relates to the field of bearing technology, and in particular to an anti-lock clutch shaft. Background Technology

[0002] In mechanical transmission systems, the clutch shaft, as a key component for enabling power engagement and disengagement, is widely used in automobiles, construction machinery, and agricultural machinery. Its core function is to quickly disconnect or transmit power according to operating conditions (such as disconnecting power when shifting gears in a car or engaging power during agricultural machinery operation). The stability of the clutch shaft directly affects the operational safety and efficiency of the equipment. Under high-load and high-speed conditions (such as rapid acceleration in a car or heavy-load operation in agricultural machinery), if the clutch shaft "locks up" due to inertia or sudden load changes (i.e., power cannot be disengaged in time and torque cannot be continuously transmitted), it may lead to serious consequences.

[0003] In the past, when replacing the existing clutch shaft, the bearing outer ring was installed inside the housing by bolts or other tools, making it inconvenient for users to remove the bearing outer ring from the housing. This made the replacement process cumbersome and affected the practicality of the device. Utility Model Content

[0016] (III) Beneficial Effects

[0017] This invention provides an anti-lock clutch shaft. It has the following beneficial effects:

[0018] 1. Through the sealing assembly, when the user rotates the base, the outer shell is brought into contact with the outer surface of the bearing. Utilizing the elasticity of the disc spring, the outer wall of the bearing squeezes the sealing gasket and sealing plate. Through the disc spring, the sealing plate and sealing gasket tightly connect the outer shell and the outer surface of the bearing, preventing gaps from appearing at the connection between the outer shell and the bearing due to long-term use, thus improving the sealing performance of the bearing.

[0019] 2. During installation, by pressing the bearing outer ring, the outer surface of the bearing outer ring moves downward, causing the abutment plate to move downward within the T-slot. At this time, the telescopic spring is compressed. When the mounting slot and the mounting groove are at the same horizontal line, the two ends of the spring are fixedly connected to the inner wall of the mounting groove and the outer surface of the locking block, respectively. The spring pushes the locking block forward, causing it to engage with the mounting slot. At this point, the bearing outer ring is inserted into the housing. During disassembly, pressing the button moves the pressing rod downward within the pressing groove. The pressing rod abuts against the inclined slot, and its downward movement causes the locking block to move backward until it separates from the mounting slot. The elastic potential energy of the telescopic spring then pops the bearing outer ring outward. The telescopic spring then moves the abutment plate upward, which in turn moves the bearing outer ring upward. No manual tools are needed to pop the bearing outer ring out of the housing, simplifying the operation and improving the device's practicality. Attached Figure Description

Detailed Implementation

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 4 , Figure 5 and Figure 6 This is the first embodiment of the present utility model. This embodiment provides an anti-lock clutch shaft, including a bearing outer ring 1, a housing 2 disposed on the outside of the bearing outer ring 1, a sealing component 4 disposed inside the housing 2, an installation component 5 disposed on the inner wall of the housing 2, and a base 3 threadedly connected to the outer surface of the housing 2.

[0031] The mounting component 5 includes a mounting groove 502 fixedly formed on the inner wall of the outer casing 2. A locking block 503 is movably disposed in the mounting groove 502. A beveled slot 5031 is formed on the outer surface of the locking block 503. A pressing rod 505 is inserted inside the outer casing 2. A mounting groove 501 is formed on the outer surface of the bearing outer ring 1. The locking block 503 engages with the mounting groove 501. A spring 504 is disposed between the outer surface of the locking block 503 and the inner wall of the mounting groove 502. A T-slot 506 is formed on the inner wall of the outer casing 2. A mounting rod 507 is disposed in the T-slot 506. An abutment plate 509 is fixedly connected to the top of the mounting rod 507. A telescopic spring 508 is sleeved on the outer surface of the mounting rod 507.

[0032] Specifically, the bottom end of the pressing rod 505 is set with an inclined surface, and the lower end of the pressing rod 505 abuts against the inclined slot 5031. When the pressing rod 505 moves downward, it causes the locking block 503 to move backward a distance longer than the depth of the mounting slot 501, so as to ensure that the locking block 503 can be separated from the mounting slot 501.

[0033] Furthermore, through the installation component 5, during installation, by pressing the outer ring 1 of the bearing, the outer surface of the outer ring 1 moves downward, causing the abutment plate 509 to move downward within the T-slot 506. At this time, the telescopic spring 508 is compressed. When the mounting slot 501 and the mounting groove 502 are at the same horizontal line, the two ends of the spring 504 are fixedly connected to the inner wall of the mounting groove 502 and the outer surface of the locking block 503, respectively. The spring 504 pushes the locking block 503 forward, causing the locking block 503 to engage with the mounting slot 501. At this time, the outer ring 1 of the bearing is inserted into the outer shell 2. During disassembly, through... Pressing the button moves the pressing rod 505 downward in the pressing groove. The pressing rod 505 abuts against the inclined slot 5031. The downward movement of the pressing rod 505 moves the locking block 503 backward until the locking block 503 separates from the mounting slot 501. Then, the elastic potential energy of the telescopic spring 508 is used to pop the outer ring 1 of the bearing outward. The telescopic spring 508 drives the abutment plate 509 to move upward, and the abutment plate 509 drives the outer ring 1 of the bearing to move upward. There is no need for manual tools to pop the outer ring 1 of the bearing out of the housing 2. The operation is simple and improves the practicality of the device.

[0034] Example 2

[0035] Reference Figure 1 , Figure 2 and Figure 3 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0036] The sealing assembly 4 includes a sealing groove 401 fixedly formed on the outer surface of the housing 2. A butterfly spring 402 is fixedly connected to the inner wall of the sealing groove 401. A sealing plate 403 is fixedly connected to the outer surface of the butterfly spring 402. A sealing gasket 404 is fixedly connected to the outer surface of the sealing plate 403.

[0037] Specifically, the sealing plate 403 is inserted into the sealing groove 401, and the width of the sealing plate 403 is smaller than the width of the sealing groove 401. The butterfly spring 402 is disposed between the sealing plate 403 and the sealing groove 401. The sealing gasket 404 is made of soft rubber, and the width of the sealing gasket 404 is larger than the width of the sealing groove 401. The upper surface of the pressing rod 505 is provided with a mounting cover to prevent the pressing rod 505 from separating from the outer casing 2. A button is provided at the end of the pressing rod 505 near the mounting cover. The inner surface of the outer casing 2 is provided with a pressing groove for the button to move. The telescopic spring 508 is sleeved on the outer surface of the mounting rod 507, and the end of the telescopic spring 508 away from the abutting plate 509 is fixedly connected to the inner bottom wall of the T-slot 506. The two ends of the telescopic spring 508 are fixedly connected to the bottom wall of the T-slot 506 and the lower surface of the abutting plate 509, respectively.

[0038] Furthermore, through the sealing assembly 4, when the user rotates the base 3, the outer shell 2 is brought into contact with the outer surface of the bearing. Utilizing the elasticity of the butterfly spring 402, the outer wall of the bearing presses against the sealing gasket 404 and the sealing plate 403. Through the butterfly spring 402, the sealing plate 403 and the sealing gasket 404 tightly connect the outer shell 2 and the outer surface of the bearing, preventing gaps from appearing at the connection between the outer shell 2 and the bearing due to long-term use, thus improving the sealing performance of the bearing.

[0039] Working principle: During installation, the worker presses the outer ring 1 of the bearing, causing the outer surface of the outer ring 1 to move downwards, which in turn moves the abutment plate 509 downwards within the T-slot 506. At this time, the telescopic spring 508 is compressed. When the mounting slot 501 and the mounting groove 502 are at the same horizontal level, the two ends of the spring 504 are fixedly connected to the inner wall of the mounting groove 502 and the outer surface of the locking block 503, respectively. The spring 504 pushes the locking block 503 forward, causing it to engage with the mounting slot 501. At this point, the outer ring 1 of the bearing is inserted into the outer shell 2. During disassembly, pressing the button moves the pressing rod 505 downwards within the pressing groove. The pressing rod 505 abuts against the inclined slot 5031, and the downward movement of the pressing rod 505 moves the locking block 503 backwards until it separates from the mounting slot 501. The elastic potential energy of the telescopic spring 508 is then utilized... The outer ring 1 of the bearing can be ejected outwards, and the abutment plate 509 is moved upwards by the telescopic spring 508. The abutment plate 509 moves the outer ring 1 of the bearing upwards. Compared with traditional technology, this device does not require manual ejection of the outer ring 1 from the outer shell 2 with tools, making the operation simple and improving the practicality of the device. Then, the outer shell 2 is placed inside the bearing and locked in place by the base 3. When the user rotates the base 3, the outer shell 2 is brought into contact with the outer surface of the bearing. Utilizing the telescopic property of the disc spring 402, the outer wall of the bearing compresses the sealing gasket 404 and the sealing plate 403. Through the disc spring 402, the sealing plate 403 and the sealing gasket 404 tightly connect the outer shell 2 and the outer surface of the bearing. Compared with traditional technology, this device can prevent gaps from appearing at the connection between the outer shell 2 and the bearing due to long-term use through the interaction of the sealing gasket 404 and the disc spring 402, thus improving the sealing performance of the bearing.
