Description

Technical Field

[0001] This invention relates to the technical field of roller clutch handling and assembly devices, and in particular to a roller clutch handling and assembly device and its usage method. Background Technology

[0002] Roller-type centrifugal clutches are primarily used to replace traditional hydraulic couplings, enabling no-load starting of motors and smoothly driving large loads such as crushers, belt conveyors, and ball mills. When an overload occurs, it automatically slips, protecting the motor and reducer from damage, thus providing overload protection during startup. Alternatively, roller-type overrunning clutches are widely used in loader gearboxes to achieve power shifting and overrunning functions, ensuring smooth vehicle operation under various working conditions. Therefore, roller-type centrifugal clutches are applied in a variety of situations. Current assembly methods require manual handling of the clutch to the assembly station, followed by placement and installation into the gearbox housing. This is difficult, prone to roller detachment, and time-consuming, resulting in a long overall installation cycle, high labor costs, and low installation efficiency. Summary of the Invention

[0003] The technical problem to be solved by the present invention is: in order to solve the problem that the existing assembly requires manual handling of the clutch to the assembly station, and then placement and installation into the gearbox housing, which is difficult to install, the rollers are prone to falling off, and the installation time is long, resulting in a long overall installation cycle, which is time-consuming, labor-intensive and inefficient. The present invention provides a roller clutch handling and assembly device and its usage method.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a roller clutch handling and assembly device, including a core cylinder, wherein the diameter of the core cylinder is less than or equal to the diameter of the inner ring of the cage on the roller clutch, and greater than or equal to the diameter of the mounting raceway formed by the rollers; the core cylinder is provided with a handle and a clamping mechanism; the clamping mechanism is used to place the core cylinder on the inner ring of the cage on the roller clutch, and when the handle is held, it can control the clamping mechanism to press against or release the roller clutch, thereby locking or unlocking the core cylinder and the roller clutch;

[0005] The clamping mechanism includes a clamping member rotatably connected to the core cylinder. The clamping member has a pressure tongue and a control section connected in sequence. The pressure tongue is located at the contact surface between the core cylinder and the roller clutch, and the control section is located at the handle. The core cylinder has a groove, and the pressure tongue is located within the groove. The control section controls the pressure tongue to swing and protrude or retract from the groove, thus enabling the pressure tongue to engage or disengage from the roller clutch. The clamping mechanism works in conjunction with the handle to facilitate the handling and assembly of the roller clutch, and to switch the state of the roller clutch. Compared to existing technologies, this solution, through the coordinated operation of the clamping mechanism and the handle, locks or unlocks the core cylinder and the roller clutch, switches the state of the roller clutch, and allows the core cylinder to be moved to the installation position for assembly when locked. This facilitates clutch handling, limits roller displacement to prevent rollers from falling, and enables rapid assembly, improving installation efficiency.

[0006] To better engage the pressure tongue against the roller clutch and lock the core cylinder to the roller clutch, in some preferred embodiments, the end of the pressure tongue that contacts the roller clutch is an arc-shaped surface, which matches the inner ring of the cage on the roller clutch. By matching the arc-shaped surface with the inner ring of the cage, the contact area with the inner ring of the cage is increased, improving the friction between the two and ensuring a stable and reliable lock between the core cylinder and the roller clutch. This also guarantees the stable and reliable handling and installation of the roller clutch.

[0007] To reduce scratches left between the pressure tongue and the roller clutch, in some preferred embodiments, the arc-shaped surface of the pressure tongue at the contact end with the roller clutch has a rounded chamfer. By designing the arc-shaped surface as a rounded chamfer, the chamfer can avoid scratches caused by sharp points contacting the roller clutch.

[0008] To further reduce scratches on the pressure tongue and roller clutch, in some preferred embodiments, the pressure tongue is made of high-molecular-weight polyethylene. Using high-molecular-weight polyethylene as the material for the pressure tongue provides elasticity and prevents scratches from being left on the roller clutch.

[0009] To implement the control section, in some preferred embodiments, the control section includes a connecting section and a gripping section, one end of the connecting section is disposed on the gripping section, and the other end of the connecting section is disposed on the depressor, the depressor being arranged parallel to the gripping section.

[0010] In some preferred embodiments, the pressure tongue and the core cylinder are rotatably connected by a pin.

[0011] To improve grip comfort, in some preferred embodiments, a grip pad is provided on the grip section.

[0012] To facilitate control of the clamping mechanism, in some preferred embodiments, a spring is provided between the pressure tongue and the core cylinder. The spring is used to ensure that the pressure tongue can press against the roller clutch and prevent the rollers from falling off, and to provide a force to overcome axial disengagement during the handling of the roller clutch.

[0013] To facilitate the installation of the mandrel and the roller clutch, in some preferred embodiments, the mandrel is annular, and its outer circumferential surface has a sequentially connected abutment section and a transition section. The abutment section is used to contact the roller clutch, and the transition section is tapered, wider at the bottom than the top, to facilitate the pressing of the roller clutch. The transition section on the outer circumferential surface of the mandrel ensures that the clutch is smoothly pressed into the tooling; simultaneously, the diameter of the mandrel is larger than the diameter of the mounting raceway, ensuring that the clutch can be smoothly pressed onto the mandrel.

[0014] A method for using a roller clutch handling and assembly device as described above, with the specific operating steps as follows:

[0015] S1. Hold the handle and place the core cylinder on the inner ring of the roller clutch retainer;

[0016] S2, the control section that holds the clamping part, and controls the tongue protrusion to contact the roller clutch, locking the core cylinder with the roller clutch;

[0017] S3. Turn the handle and move the rollers in the roller clutch to change position, so that the roller clutch switches from overrunning state to engagement state.

[0018] S4. Use the control handle to move the roller clutch to the installation position of the equipment for installation;

[0019] S5. After the roller clutch is installed, turn the handle and move the rollers inside the roller clutch to switch the roller clutch from the engaged state to the overrunning state.

[0020] S6. Control the control section of the clamping component and retract the pressure tongue into the slot. The pressure tongue disengages from the roller clutch, unlocking the core cylinder from the roller clutch. Remove the core cylinder from the roller clutch to complete the installation of the roller clutch.

[0021] The beneficial effects of this invention are as follows: The present invention provides a roller clutch handling and assembly device and its method of use. Through the coordinated operation of the handle and the clamping mechanism, the core cylinder and roller clutch are locked or unlocked, switching the state of the roller clutch. When the core cylinder and roller clutch are locked, the device can be transported to the installation station for assembly. This facilitates clutch handling, limits roller displacement to prevent rollers from falling off, and enables rapid assembly, improving efficiency. It avoids the problems of existing assembly methods that require manual handling of the clutch to the assembly station, placement, and installation into the gearbox housing, which is difficult, prone to roller detachment, and time-consuming, resulting in a long overall installation cycle, high labor costs, and low installation efficiency.

[0038] like Figure 1-14 As shown, a roller clutch handling and assembly device includes a core cylinder 1, which is annular. The diameter of the core cylinder 1 is less than or equal to the diameter of the inner ring of the cage on the roller clutch, and greater than or equal to the diameter of the mounting raceway formed by the rollers. The core cylinder 1 is provided with a handle 2 and a clamping mechanism. The handle 2 is arched, and both ends of the handle 2 are fixed to the upper end face of the core cylinder 1 by screws. The clamping mechanism is used to place the core cylinder 1 on the inner ring of the cage on the roller clutch, and when the handle 2 is held, it can control the clamping mechanism to press against or release the roller clutch, thereby locking or unlocking the core cylinder 1 with the roller clutch.

[0039] The clamping mechanism includes a clamping member 3 rotatably connected to the core cylinder 1. The clamping member 3 has a pressure tongue 4 and a control section 5 connected in sequence. The pressure tongue 4 is located at the contact surface between the core cylinder 1 and the roller clutch. The control section 5 is located at the handle 2. The core cylinder 1 is provided with a groove 6. The pressure tongue 4 is located in the groove 6. The control section 5 is used to control the pressure tongue 4 to swing and protrude or retract from the groove 6, so that the pressure tongue 4 abuts against or disengages from the roller clutch. The clamping mechanism works in conjunction with the handle 2 to realize the handling and assembly of the roller clutch, and to switch the state of the roller clutch.

[0040] In this embodiment, the diameter of the core cylinder 1 is less than or equal to the diameter of the inner ring of the cage on the roller clutch, and greater than the diameter of the mounting raceway formed by the rollers. Its main function is that when the core cylinder 1 is pressed against the roller clutch by the clamping mechanism, it can control the rotation of the cage and switch the roller clutch from the overrunning state to the engaged state. One side of the roller will contact the outer peripheral surface of the core cylinder 1, and the mounting raceway formed by several rollers will abut against the outer peripheral surface of the core cylinder 1, thereby restricting the rollers and preventing them from falling off. At the same time, the core cylinder 1 and the roller clutch are locked together to ensure stability and reliability during transportation and to avoid the problem of the roller clutch falling off.

[0041] Switching the state of a roller clutch mainly involves switching the roller clutch between the overrunning state and the engaged state.

[0042] The end of the pressure tongue 4 that contacts the roller clutch is an arc-shaped surface 7, which matches the inner ring of the upper cage of the roller clutch. The arc-shaped surface 7 at the end of the pressure tongue 4 that contacts the roller clutch has a rounded chamfer. The material of the pressure tongue 4 is high-molecular-weight polyethylene.

[0043] The control section 5 includes a connecting section 8 and a gripping section 9. One end of the connecting section 8 is disposed on the gripping section 9, and the other end of the connecting section 8 is disposed on the tongue depressor 4. The tongue depressor 4 is disposed parallel to the gripping section 9.

[0044] The pressure tongue 4 and the core cylinder 1 are rotatably connected by a pin, so that the clamping part 3 can be rotatably installed on the core cylinder 1. The gripping section 9 is provided with a gripping pad 10, which can improve the operator's gripping comfort.

[0045] A spring 11 is provided between the pressure tongue 4 and the core cylinder 1. The spring 11 is used to enable the pressure tongue 4 to press against the roller clutch and prevent the rollers from falling off, and to provide the roller clutch with the force to overcome axial disengagement during the handling process.

[0046] The outer circumferential surface of the core cylinder 1 has a contact section 12 and a transition section 13 connected in sequence. The contact section 12 is used to contact the roller clutch. The transition section 13 is a cone shape with a smaller top and a larger bottom. The transition section 13 is used to facilitate the pressing in of the roller clutch. In this embodiment, the diameter of the core cylinder 1 is larger than the diameter of the mounting raceway formed by the rollers.

[0047] Example 2 is an application of Example 1, specifically: a method for using a roller clutch handling and assembly device as described above, with the following specific operating steps:

[0048] S1. Hold the handle 2 with your hand and place the core cylinder 1 in the inner ring of the upper retainer of the roller clutch;

[0049] S2. Then grip the gripping section 9 at the control section 5 on the clamping part 3, and control the tongue 4 to protrude from the slot 6 to contact the retainer of the roller clutch, thereby locking the core cylinder 1 and the roller clutch.

[0050] S3. Then turn the handle 2 and drive the rollers in the roller clutch to move, so that the roller clutch switches from the overrunning state to the engaging state. The inner raceway formed by the rollers contacts the core cylinder 1, ensuring that the rollers are restricted and preventing the rollers from falling during transportation. The rollers also contact the outer circumferential surface of the core cylinder 1, so that the mounting raceway formed by the rollers interacts with the core cylinder 1 and provides the roller clutch with the force to overcome axial disengagement during transportation.

[0051] S4. Then, use handle 2 to move the roller clutch to the installation station of the equipment for installation.

[0052] S5. After the roller clutch is installed, turn the handle 2 and drive the rollers in the roller clutch to move, so that the roller clutch switches from the engaged state to the overrunning state, the rollers separate from the outer circumferential surface of the core cylinder 1, and the installation raceway formed by the rollers separates from the core cylinder 1.

[0053] S6. Control the control section 5 of the clamping component 3 and retract the pressure tongue 4 into the slot 6. The pressure tongue 4 disengages from the roller clutch, unlocking the core cylinder 1 from the roller clutch. Remove the core cylinder 1 from the roller clutch to complete the installation of the roller clutch.

[0054] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
