Description
Technical Field
[0001] The utility model relates to the technical field of motor connection components, in particular to a connection mechanism for a high-speed ratio hydraulic motor. Background Art
[0002] High-speed hydraulic motors are devices used in hydraulic transmission systems. Their primary function is to convert the pressure energy of a liquid into mechanical energy to drive the rotational or linear motion of various mechanical devices. With the continuous advancement of industrial automation and intelligentization, the market demand for high-speed hydraulic motors will continue to grow. Demand for high-performance hydraulic motors will continue to increase, particularly in high-end equipment manufacturing, aerospace, and new energy vehicles. Furthermore, with growing environmental awareness and the popularization of green manufacturing and sustainable development concepts, the hydraulic motor industry will also place greater emphasis on energy conservation, emission reduction, and resource efficiency.
[0003] In the existing technology, the output end far away from one end of the high-speed ratio hydraulic motor is prone to violent vibration and unstable shaking. This vibration and swing not only affects the operating stability of the equipment, but also causes the connection part with the load-bearing rod to loosen or detach in extreme cases, causing serious safety accidents and posing a threat to the safety of operators and the integrity of the equipment. The existing connection mechanism usually adopts reinforcement measures such as annular iron sheets and bolts to enhance the stability of the key connection to prevent the separation between the motor and the load-bearing equipment. However, the use of annular iron sheets and bolts will cause scratches on the surface of the load-bearing equipment, affecting the appearance and service life of the equipment. Secondly, although the stability of the connection can be improved to a certain extent through reinforcement, it is still difficult to completely control the terminal shaking of the output end, especially under high load or long-term operation. This shaking will cause fatigue damage to the connection, increasing safety hazards. Utility Model Content
[0004] The purpose of the utility model is to solve the shortcomings in the prior art and to propose a connection mechanism for a high-speed ratio hydraulic motor.
[0005] The cam is fixedly provided with an axial piston rod and is provided with an axial piston rod of the hydraulic motor, and an axial piston rod of the hydraulic motor is connected with the hydraulic cylinder to the hydraulic cylinder to the hydraulic cylinder.
[0006] Preferably, a top frame is fixed to the bottom of the base, and a bottom base is slidably connected to the inner wall of the top frame. The bottom of the bottom base is fixed to the inner wall of the workbench, and a buffer spring is fixed to the top of the bottom base, and the top of the buffer spring is fixed to the bottom of the base. In the prior art, due to the working principle and design characteristics of the high-speed ratio hydraulic motor, the output end away from one end of the motor is prone to violent vibration and unstable shaking during operation. Such vibration and shaking will not only affect the operating stability of the equipment, but also induce greater vibration energy during the production process, causing the bottom of the equipment to continuously collide with the ground, thereby generating noise pollution. Such noise will not only cause discomfort to the staff and affect the comfort of the working environment, but also cause long-term damage to the hearing health of the operators. In addition, long-term The continuous vibration will also cause the connection and fixation between the various components of the equipment to gradually fail. Over time, this vibration will cause problems such as loose bolts, cracked welds or structural fatigue, thereby reducing the overall service life of the equipment. To address such problems, the utility model solves this problem by installing a buffer spring. When production starts, the vibration is transmitted to the buffer spring through the base. The buffer spring absorbs the vibration and accumulates elastic potential energy. When the buffer spring needs to release the elastic potential energy, the friction coefficient between the inner wall of the top frame and the side of the bottom base, as well as the side of the top frame and the inner wall of the workbench is large, which makes the friction force large, limiting the release of the elastic potential energy of the buffer spring, and converting the elastic potential energy into internal energy through friction, thereby alleviating the impact of vibration, thereby improving the service life of the equipment and improving the user experience.
[0007] Preferably, the four corners of the bottom base are provided with T-slides, and the inner walls of the T-slides are slidably connected to T-slides. In the prior art, vibration is a problem that cannot be ignored during the operation of mechanical equipment such as hydraulic motors. This vibration exists not only in the up and down directions, but also in the left and right directions. When the base is subjected to left and right vibrations, its influence will be transmitted to the entire equipment, especially the top frame. Due to the close connection between the top frame and other components, this left and right vibration will cause continuous collisions between them. Over time, this continuous collision will cause scratches and wear to become serious. These wears will not only affect the normal operation of the equipment, but also reduce the service life of the equipment. To solve such problems, the utility model adopts the method of installing T-slides to achieve the solution, and realizes the matching and sliding of the T-slide and the T-slide, thereby limiting the movement path of the top frame, improving the stability of the equipment, preventing scratches, and increasing friction, further alleviating and transforming the release of elastic potential energy, thereby achieving the effect of increasing the service life of the equipment.
[0008] Preferably, a ladder limit ring is fixed on the circumference of the rotating ring disk, and the surface of the ladder limit ring is slidably connected to the inner wall of the pressure equalizing cylinder, so that the rotating ring disk can only rotate along a predetermined track on the inner wall of the pressure equalizing cylinder through the restriction of the ladder limit ring, thereby achieving the effect of improving the stability of the equipment.
[0009] Preferably, a rubber pad is fixed to the bottom of the T-slider to prevent collisions between components and to increase the service life of the equipment.
[0010] Preferably, an anti-slip groove is provided on the inner wall of the arc pressure piece, thereby increasing the friction coefficient, improving the friction force, and achieving the effect of increasing the service life of the equipment.
[0011] Preferably, an auxiliary bearing seat is fixed to the inner wall of the trough, which further prevents the component from shaking and improves the stability of equipment use.
[0012] Beneficial effects:
[0013] 1. In the prior art, the output end away from one end of the high-speed ratio hydraulic motor is prone to violent vibration and unstable shaking. This vibration and swing not only affects the operational stability of the equipment, but also causes the connection part with the load-bearing rod to loosen or disengage in extreme cases, causing serious safety accidents and posing a threat to the safety of operators and the integrity of the equipment. Existing connection mechanisms usually use reinforcement measures such as annular iron sheets and bolts to enhance the stability of the key connection to prevent the motor from disengaging from the load-bearing equipment. However, the use of annular iron sheets and bolts will scratch the surface of the load-bearing equipment, affecting the appearance and service life of the equipment. Secondly, although the connection stability can be improved to a certain extent by reinforcement, it is still difficult to completely control the terminal shaking of the output end. Especially under high load or long-term operation, this shaking will cause fatigue damage to the connection, increasing safety hazards. To solve this problem, the utility model adopts the method of installing arc pressure parts to solve it. After the staff connects the output shaft of the hydraulic motor body with the connected meshing cylinder of the force-bearing equipment, the key connection between the two is slid into the hollow part of the rotating ring disk. Then the staff rotates the rotating ring disk to align the adjustment part with the adjustment window. The adjustment part is turned from the adjustment window with a screwdriver or other tool to engage the active bevel gear and rotate the bevel gear ring. The square vortex part rotates and engages accordingly, causing the vortex parts to gather towards the center, so that the arc pressure part presses the key connection of the two toward the center, greatly increasing the pressure between the two, thereby increasing friction, and fixing it through pressure to prevent it from detaching, thereby achieving the effect of improving the stability of the equipment.
[0014] 2. In the prior art, due to the working principle and design features of the high-speed ratio hydraulic motor, the output end far away from one end of the motor is prone to violent vibration and unstable shaking during operation. Such vibration and shaking will not only affect the operational stability of the equipment, but also induce large vibration energy during the production process, causing the bottom of the equipment to constantly collide with the ground, thereby generating noise pollution. This noise will not only cause discomfort to the staff and affect the comfort of the working environment, but also cause long-term damage to the hearing health of the operators. In addition, long-term continuous vibration will also cause gradual failure of the connection and fixation between the various components of the equipment. Over time, This vibration can cause problems such as loose bolts, cracked welds or structural fatigue, thereby reducing the overall service life of the equipment. To address this problem, the utility model solves it by installing a buffer spring. When production starts, the vibration is transmitted to the buffer spring through the base. The buffer spring absorbs the vibration and accumulates elastic potential energy. When the buffer spring needs to release the elastic potential energy, the friction coefficient between the inner wall of the top frame and the side of the bottom base, as well as the side of the top frame and the inner wall of the workbench is large, which makes the friction force large, limiting the release of the elastic potential energy of the buffer spring, and converting the elastic potential energy into internal energy through friction, thereby alleviating the impact of vibration, thereby improving the service life of the equipment and enhancing the user experience.
[0015] 3. In the prior art, vibration is a problem that cannot be ignored during the operation of mechanical equipment such as hydraulic motors. This vibration exists not only in the up and down directions, but also in the left and right directions. When the base is subjected to left and right vibrations, its impact will be transmitted to the entire equipment, especially the top frame. Due to the close connection between the top frame and other components, this left and right vibration will cause continuous collisions between them. As time goes by, this continuous collision will cause scratches and wear to become serious. These wears will not only affect the normal operation of the equipment, but also reduce the service life of the equipment. To solve such problems, the utility model adopts the method of installing T-slides to solve them, and realizes the matching and sliding of T-slides and T-slots, thereby limiting the movement path of the top frame, improving equipment stability, preventing scratches, and increasing friction at the same time, further alleviating and transforming the release of elastic potential energy, thereby achieving the effect of increasing the service life of the equipment.

Based on the embodiments in the implementation manner, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the present invention.
[0026] The specific embodiments of the present utility model are described below with reference to the accompanying drawings. Specific embodiment:

The inner wall of the cylinder 203 is rotatably connected to a rotating ring disk 205, and the inner wall of the rotating ring disk 205 is rotatably connected to a bevel gear rotating ring 206. An active bevel gear 207 is meshed on one side of the bevel gear rotating ring 206, and an adjusting part 208 is fixed to one end of the active bevel gear 207. A square vortex 209 is fixed to the other side of the bevel gear rotating ring 206. A vortex member 2010 is meshed on the surface of the square vortex member 209.

A top frame 301 is fixed to the bottom of the base 202, and the inner wall of the top frame 301 is slidably connected to the bottom base 302. The bottom of the bottom base 302 is fixed to the inner wall of the workbench 2, and a buffer spring 3 is fixed to the top of the bottom base 302. The top of the buffer spring 3 is fixed to the bottom of the base 202. Due to the working principle and design characteristics of the high-speed hydraulic motor, its output end far away from one end of the motor is prone to violent vibration and unstable shaking during operation. This vibration and shaking will not only affect the operating stability of the equipment, but also cause greater vibration energy during the production process, causing the bottom of the equipment to continuously collide with the ground, thereby generating noise pollution. This noise will not only cause discomfort to the staff and affect the comfort of the working environment, but also cause long-term damage to the hearing health of the operators. In addition, long-term Continuous vibration will also cause gradual failure of the connection and fixation between the various components of the equipment. Over time, this vibration will lead to problems such as loose bolts, cracked welds or structural fatigue, thereby reducing the overall service life of the equipment. This is solved by installing a buffer spring 3. When production starts, the vibration is transmitted to the buffer spring 3 through the base 202. The buffer spring 3 absorbs the vibration and accumulates elastic potential energy. When the buffer spring 3 needs to release the elastic potential energy, the friction coefficient between the inner wall of the top frame 301 and the side of the bottom base 302 and the side of the top frame 301 and the inner wall of the workbench 2 is large, which makes the friction force large, limiting the release of the elastic potential energy of the buffer spring 3, and converting the elastic potential energy into internal energy through friction, thereby alleviating the impact of vibration, thereby improving the service life of the equipment and improving the user experience.
[0029] T-slides 303 are provided at the four corners of the bottom base member 302, and a T-slide 304 is slidably connected to the inner wall of the T-slide 303. During the operation of mechanical equipment such as hydraulic motors, vibration is a problem that cannot be ignored. This vibration exists not only in the up and down directions, but also in the left and right directions. When the base 202 is subjected to left and right vibrations, its impact will be transmitted to the entire equipment, especially the top frame member 301. Due to the close connection between the top frame member 301 and other components, this left and right vibration will cause continuous collisions between them. Over time, this continuous collision will cause scratches and wear to become serious. These wears will not only affect the normal operation of the equipment, but also reduce the service life of the equipment. The problem is solved by installing a T-slide 304, which realizes the matching and sliding of the T-slide 304 and the T-slide 303, thereby limiting the movement path of the top frame member 301, improving the stability of the equipment, preventing scratches, and increasing friction. It further alleviates and transforms the release of elastic potential energy, thereby achieving the effect of increasing the service life of the equipment. A ladder limit ring 2013 is fixed to the circumference of the rotating ring disc 205. The surface of the ladder limit ring 2013 is slidably connected to the inner wall of the pressure equalizing cylinder 203. Through the restriction of the ladder limit ring 2013, the rotating ring disc 205 can only rotate along the predetermined track on the inner wall of the pressure equalizing cylinder 203, thereby improving the stability of the equipment. A rubber pad is fixed to the bottom of the T-slider 304 to prevent collisions between components and thus improve the service life of the equipment. Anti-skid grooves are provided on the inner wall of the arc pressure member 2012 to increase the friction coefficient and improve the friction force, thereby improving the service life of the equipment. An auxiliary bearing seat 103 is fixed to the inner wall of the sink 201 to further prevent the components from shaking and thus improve the stability of the equipment.
[0030] The working principle of the present invention is as follows: after the staff connects the output shaft 101 of the hydraulic motor body 1 with the connected meshing cylinder 102 of the force-bearing equipment by a key, the key connection between the two is slid into the hollow part of the rotating ring disk 205, and then the staff rotates the rotating ring disk 205 to align the adjusting member 208 with the adjusting window 204, and uses a tool such as a screwdriver to screw the adjusting member 208 from the adjusting window 204 to make the active bevel gear 207 engage and the bevel gear dynamic ring 206 rotate, and the square vortex member 209 rotates and engages accordingly to make the vortex member 2010 gather toward the center, so that the arc pressure member 2012 synchronously presses the key connection between the two toward the center, greatly increasing the pressure between the two, thereby increasing the friction, fixing it by pressure, and preventing it from detaching.
