Description

Technical Field

[0001] This utility model belongs to the field of mechanical equipment installation technology, and specifically discloses a special tool for installing the gear system of a product. Background Technology

[0002] The gear transmission mechanism of a certain product mainly consists of gear assemblies, a DC motor, a tachometer motor, and an angle sensor. During operation, the DC motor is powered on and runs, driving the actuator via the motor shaft gear and several gear assemblies. The final gear assembly is a double-plate thin gear structure, with a spring connecting the two thin gears. The misalignment of the double-plate thin gears eliminates meshing backlash, improving transmission accuracy. During assembly, the motor is typically installed while maintaining the misalignment of 3-5 teeth on the double-plate thin gears to achieve gear engagement. Due to the large number of teeth and diameter of the thin gears, and the high stiffness of the springs, actual assembly often involves one person manually holding the misaligned teeth of the double-plate thin gears while another person installs the DC motor. This frequently results in the gear system failing to mesh smoothly, leading to high operational difficulty and low work efficiency. Furthermore, during motor shaft gear installation, the gear must first be fixed to the motor shaft, then clamped with needle-nose pliers or other tools to prevent the motor shaft from rotating when the nut is tightened, and finally the slotted nut is tightened. This operation is inconvenient and easily damages the motor shaft gear. Therefore, there is a need to invent a gear system installation tool that is easy to operate, saves time and effort, can not only realize the staggered tooth installation of double thin gears, but also facilitate the installation of motor shaft gears, effectively improve work efficiency and save labor costs.

[0003] To address the problems in the background art, this utility model discloses a special tool for installing a product gear system, including a toothed end and a fixed end. The toothed state is fixed by the meshing of the internal gear of the toothed end with the double-plate thin gear, and the motor shaft gear is fixed by the internal gear of the fixed end. This facilitates the installation of the toothed state of the double-plate thin gear and the motor shaft gear, thereby improving installation efficiency.

The replaceable end heads include a staggered-tooth end head 3 and a fixed-tooth end head 4. The staggered-tooth end head 3 includes a gear segment 3.1 with an arc-shaped plate structure. The gear segment 3.1 is detachably connected to the handle 1 via a connecting handle 3.2 connected to its outer circular surface. A first internal gear, matching the double-plate thin gear requiring staggered teeth, is provided on the inner circular surface of the gear segment 3.1. The fixed-tooth end head 4 includes a ring-shaped fixing ring. A second internal gear, matching the motor shaft gear, is provided on the inner circular surface of the fixing ring. The fixing ring is detachably connected to the handle 1 via the connecting handle 3.2 connected to its outer circular surface. Preferably, the staggered-tooth end head 3... The connecting handle 3.2 of the fixed tooth end 4 is inserted and connected to the handle 1 and locked by the set screw 2. During operation, the toothed end 3 or the fixed tooth end 4 can be connected to the connecting end of the handle 1 as needed. Different specifications of toothed end 3 or fixed tooth end 4 can also be connected to the connecting end of the handle 1 as needed. The tool uses the first internal gear of the toothed end 3 to mesh with the double thin gear to fix the toothed state, and uses the second internal gear of the fixed tooth end 4 to fix the motor shaft gear, which facilitates the installation of the toothed double thin gear and the motor shaft gear.

Then, push the tool along the axial direction of the moving gear 6 to ensure that the first internal gear meshes with both the fixed gear 5 and the moving gear 6 simultaneously. At this time, without any other external force, the offset tooth state of the double-plate thin gear can remain unchanged, and then the motor installation operation can be performed. When using the fixed tooth end 4, first assemble the motor shaft gear onto the motor shaft, and then put the second internal gear of the fixed tooth end 4 onto the motor shaft gear. Hold the tool handle 1 with one hand and tighten the slotted nut with the other hand. This effectively improves the convenience of motor shaft gear installation, avoids damage to the motor shaft gear, and improves work efficiency. This utility model is a special tool for installing product gear systems. It is safe and convenient to operate, and can quickly realize the installation of a certain product gear system. It improves work efficiency while ensuring work safety and reliability, and meets the usage requirements.

[0023] A special tool for installing a product gear system includes a strip-shaped handle 1, a tooth-shifting end 3 connected to one end of the handle 1, and a tooth-fixing end 4 connected to the other end of the handle 1. The tooth-shifting end 3 includes a gear segment 3.1 with an arc-shaped plate structure. The gear segment 3.1 is connected to the handle 1 via a connecting handle 3.2 connected to its outer circular surface. A first internal gear matching the double-plate thin gear that needs to be toothed is provided on the inner circular surface of the gear segment 3.1. The tooth-fixing end 4 includes a ring-shaped fixing ring. A second internal gear matching the motor shaft gear is provided on the inner circular surface of the fixing ring.

The connecting handle 3.2 of the tooth-shifting end 3 and the tooth-fixing end 4 are connected together. 2. The connecting handle 1 is fixedly connected, integrally formed or detachably connected. Preferably, the connecting handles 3.2 of the toothed end 3 and the fixed end 4 are respectively inserted and connected to the handle 1 and locked by the set screw 2. The tool uses the first internal gear of the toothed end 3 to mesh with the double thin gear to fix the toothed state, and uses the second internal gear of the fixed end 4 to fix the motor shaft gear, which facilitates the installation of the toothed double thin gear and the motor shaft gear. The replaceable end can also be adjusted according to the parameters of the double thin gear and the motor shaft gear to adapt to the installation of toothed double thin gears and motor shaft gears of different specifications. During operation, toothed end 3 and / or fixed end 4 of different specifications can be conveniently connected to both ends of the handle 1 as needed.

[0024] As an optional design, the preferred tool for installing the product gear system has the following parameters: the module, pitch circle diameter, and pressure angle of the first internal gear are consistent with the parameters of the double-plate thin gear that requires misalignment; and the number of teeth of the first internal gear is not less than 1 / 6 of the number of teeth of the double-plate thin gear, ensuring smooth meshing of the gear teeth and locking the misaligned state of the double-plate thin gear after meshing. The parameters of the second internal gear are consistent with the parameters of the motor shaft gear, which effectively improves the convenience of motor shaft gear installation and avoids damage to the motor shaft gear. By accurately matching the gear parameters, this tool ensures the stability and accuracy of gear meshing during installation, effectively improving the installation efficiency of the product gear system.

[0025] The working process of this utility model is as follows:

[0026] When it is necessary to fix the misaligned state of the double-plate thin gears in the product gear system, use the misaligned end 3 and hand-held tool to enter from the moving gear side of the double-plate thin gear. The first internal gear meshes with the teeth of the moving gear 5. Rotate along the spring contraction direction in the double-plate thin gear to make the moving gear 6 misaligned with the fixed gear 5 by 3 to 5 teeth. Then push the tool along the axial direction of the moving gear 6 to ensure that the first internal gear meshes with both the fixed gear 5 and the moving gear 6 at the same time. At this time, without the action of other external forces, the misaligned state of the double-plate thin gears can remain unchanged. Then, the motor installation operation can be carried out.

[0027] When installing the motor shaft gear, first assemble the motor shaft gear onto the motor shaft. Hold the handle 1 and put the second internal gear of the fixed end 4 onto the motor shaft gear. Hold the tool handle 1 with one hand and tighten the slotted nut with the other.
