Description

Technical Field

[0001] This utility model relates to the field of sprocket box technology, specifically a transmission device for a skid steer loader sprocket box. Background Technology

[0002] The sprocket box of a skid steer loader is a key component of the loader's drive system, primarily responsible for transmitting engine power to the drive wheels. The function and structural design of the sprocket box are crucial to its working efficiency and durability. The sprocket box connects the engine to the drive system of the wheels, transmitting the power generated by the engine to the drive chain or wheels, ensuring that the machine can move forward, backward, or turn smoothly. The sprocket box is usually equipped with a lubrication system to reduce friction between internal components and extend its service life.

[0003] In the current use of sprocket boxes, the lack of a heat dissipation structure results in high frictional temperatures of the internal sprocket drive. Without heat dissipation, the internal temperature of the entire device is prone to prolonged high temperatures, which can accelerate the aging of the device and affect its stability. Furthermore, it is inconvenient to apply lubricating oil, and subsequent disassembly and maintenance are required, which is quite cumbersome. Therefore, it is necessary to provide a new transmission device for skid steer loader sprocket boxes to solve the above-mentioned technical problems. Utility Model Content

[0004] The purpose of this invention is to provide a transmission device for the sprocket box of a skid steer loader, which has the advantages of rapid heat dissipation and easy application to extend the maintenance cycle, thus solving the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a transmission device for a skid steer loader sprocket box, comprising: a box body; a drive motor fixedly connected to the bottom of the box body; a drive gear fixedly connected to one end of the output shaft of the drive motor; two driven gears rotatably connected inside the box body; a heat-absorbing plate fixedly connected inside the box body; heat dissipation fins evenly fixedly connected to the outside of the heat-absorbing plate; a lubricating fluid tank fixedly connected to the outside of the box body; a connecting pipe fixedly connected to the outside of the lubricating fluid tank; branch pipes fixedly connected to the outside of the connecting pipe; and nozzles evenly fixedly connected to the outside of the branch pipes. In use, by coordinating two chains, which are respectively fitted onto the outside of the two driven gears and the drive gear, [the following is possible:] This design allows a single drive motor to synchronously drive two driven gears. During operation, the heat absorption plate absorbs heat from inside the housing, which is then transferred to the heat sink via heat transfer. The heat sink then contacts the air to exchange heat and cool down. This process of heat transfer from high to low temperature achieves heat dissipation, preventing long-term high temperatures inside the housing from affecting the overall stability of the device. Additionally, lubricant from the lubrication tank can enter the branch pipes through connecting pipes and drip out through nozzles, allowing the lubricant to coat the chain and sprockets. This improves the protection of the sprockets, extends maintenance time, reduces the cost of frequent manual maintenance, and decreases the number of times the device needs to be opened, thus lowering the failure rate.

[0006] Preferably, the heat-absorbing plate is embedded inside the housing, with one side of the heat-absorbing plate located inside the housing and the other side located outside the housing. Both driven gears are rotatably connected inside the housing. By using two chains that are respectively fitted around the two driven gears and the transmission gear, the two driven gears can be synchronously driven to rotate by a single transmission motor.

[0007] Preferably, the drive motor is fixedly connected to the outside of the housing, the drive gear is rotatably connected to the inside of the housing, and the drive motor is used in combination with a reducer and other structures.

[0008] Preferably, the heat sink has uniformly distributed heat dissipation holes inside, which can increase the contact area between the heat sink and the air and improve the heat dissipation efficiency.

[0009] Preferably, the branch pipe is embedded inside the housing, and the nozzle extends into the housing, allowing lubricant to drip onto the outside of the sprocket.

[0010] Preferably, mounting plates are fixedly connected to both sides of the outer side of the housing, and screws are rotatably connected to the internal threads of the mounting plates. The screws and mounting plates are used together to achieve overall installation of the housing.

[0011] Preferably, a limiting spring is sleeved on the outside of the screw. The limiting spring is made of stainless steel. The elastic force of the limiting spring can act on the screw in the opposite direction, which makes the screw more stable after the screw thread is rotated and installed, and it will not easily loosen or fall off.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] I. In use, this utility model, by combining two chains respectively fitted around the two driven gears and the transmission gear, allows a single transmission motor to synchronously drive the two driven gears to rotate. During use, the heat absorption plate absorbs heat from inside the box, and then transfers the heat to the heat sink through heat transfer. Finally, the heat sink contacts the air to complete heat exchange and cooling. In this process, heat dissipation is achieved by transferring heat from high temperature to low temperature, thus avoiding long-term high temperature inside the box from affecting the stability of the overall device.

[0014] Second, in the process of using this utility model, the lubricant inside the lubricant tank can enter the interior of the branch pipe through the connecting pipe, and finally drip out through the nozzle, so that the lubricant can be applied to the outside of the chain and sprocket, which can improve the protection of the sprocket, extend the maintenance time, reduce the cost of frequent manual maintenance, and reduce the number of times the seal is opened, thus reducing the failure rate.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a transmission device for a skid steer loader sprocket box, comprising: a box body 1, a drive motor 5 fixedly connected to the bottom of the box body 1, a drive gear 7 fixedly connected to one end of the output shaft of the drive motor 5, two driven gears 6 rotatably connected inside the box body 1, a heat absorption plate 8 fixedly connected inside the box body 1, heat sinks 12 evenly fixedly connected to the outside of the heat absorption plate 8, a lubricating fluid tank 4 fixedly connected to the outside of the box body 1, a connecting pipe 9 fixedly connected to the outside of the lubricating fluid tank 4, branch pipes 10 fixedly connected to the outside of the connecting pipe 9, and nozzles 14 evenly fixedly connected to the outside of the branch pipes 10. In use, by coordinating two chains, which are respectively fitted onto the outside of the two driven gears 6 and the drive gear 7, a transmission device can be used to drive the sprocket box. The motor 5 can synchronously drive the two driven gears 6 to rotate. During use, the heat absorption plate 8 absorbs the heat inside the housing 1 and then transfers it to the heat sink 12 through heat transfer. Finally, the heat sink 12 contacts the air to complete heat exchange and cooling. In the process, heat transfer is achieved by transferring heat from high temperature to low temperature, which avoids the long-term high temperature inside the housing 1 from affecting the stability of the overall device. At the same time, during use, the lubricant in the lubricant tank 4 can enter the interior of the branch pipe 10 through the connecting pipe 9 and finally drip out through the nozzle 14. This allows the lubricant to be applied to the outside of the chain and sprocket, which can improve the protection of the sprocket, extend the maintenance time, reduce the cost of frequent manual maintenance, and reduce the number of times the package is opened, thus reducing the failure rate.

[0022] The heat absorption plate 8 is embedded inside the housing 1. One side of the heat absorption plate 8 is located inside the housing 1, and the other side is located outside the housing 1. Both driven gears 6 are rotatably connected inside the housing 1. By matching two chains, which are respectively sleeved on the outside of the two driven gears 6 and the transmission gear 7, the two driven gears 6 can be synchronously driven to rotate by a transmission motor 5.

[0023] The drive motor 5 is fixedly connected to the outside of the housing 1, and the drive gear 7 is rotatably connected to the inside of the housing 1. The drive motor 5 is used in combination with a reducer and other structures.

[0024] The heat sink 12 has uniformly distributed heat dissipation holes 13 inside. The heat dissipation holes 13 can increase the contact area between the heat sink 12 and the air, thereby improving the heat dissipation efficiency.

[0025] The branch pipe 10 is embedded inside the housing 1, and the nozzle 14 extends into the housing 1. The nozzle 14 can drip lubricant onto the outside of the sprocket.

[0026] Mounting plates 2 are fixedly connected to both sides of the outer side of the housing 1. Screws 3 are rotatably connected to the internal threads of the mounting plates 2. The screws 3 and the mounting plates 2 are used together to achieve the overall installation of the housing 1.

[0027] When the drive mechanism of the skid steer loader sprocket box is in use, two chains are respectively mounted on the outside of two driven gears 6 and a drive gear 7, so that a drive motor 5 can synchronously drive the two driven gears 6 to rotate. At the same time, during use, the heat absorption plate 8 can absorb the heat inside the box 1, and then transfer the heat to the heat sink 12 through heat transfer. Finally, the heat sink 12 comes into contact with the air to complete heat exchange and cooling.

[0028] Please see Figures 1 to 4 This utility model provides a technical solution: a transmission device for a skid steer loader sprocket box, wherein a limiting spring 11 is sleeved on the outside of the screw 3. The limiting spring 11 is made of stainless steel. The elastic force of the limiting spring 11 can act on the screw 3 in the opposite direction, which makes the screw 3 more stable after the thread is rotated and installed, and will not easily loosen or fall off.

[0029] When using the drive unit of the skid steer loader sprocket box, the long-term high temperature inside the box 1 should be avoided to prevent it from affecting the stability of the overall device. At the same time, during use, the lubricant inside the lubricant tank 4 can enter the interior of the branch pipe 10 through the connecting pipe 9 and finally drip out through the nozzle 14, so that the lubricant can be applied to the outside of the chain and sprocket.

[0030] The standard parts used in this embodiment can be purchased directly from the market, while the non-standard structural parts described in the specification and drawings can be processed without any doubt based on existing technical common sense. At the same time, the connection methods of each component adopt mature conventional methods in the existing technology, and the machinery, parts and equipment all adopt conventional models in the existing technology, so they will not be described in detail here.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
