Description

Technical Field

[0001] This utility model relates to the technical field of measuring tools, and in particular to a special tool for measuring backlash in side-push transmissions. Background Technology

[0002] Gear backlash refers to the amount of circumferential wobble of one gear when the other is fixed in an assembled gear pair, calculated as the arc length on the pitch circle. To ensure a proper lubricating film forms between the gear teeth and to prevent jamming due to thermal expansion caused by increased gear operating temperature, appropriate gear backlash is necessary during meshing. Currently, gear backlash is mainly measured using a dial indicator fixed next to the part being measured. With the output shaft fixed, the input shaft is moved back and forth, and the backlash of the measured gear is observed by the changes in the dial indicator scale. However, often due to the position, size, and spatial relationships of the gear being measured, it is impossible to inspect the gear backlash directly. Gear pair backlash is a crucial indicator for product performance and service life, and is a key quality control indicator during assembly.

[0003] In the prior art, patent document CN219674995U discloses a gear backlash measuring tool, including a base and a curved frame; a column is provided on the top of the base, a worktable is provided on the top of the column, a vertical plate is provided on the top of the worktable, a motor is provided on one side of the vertical plate, a rotating shaft is provided through the output end of the motor and through the vertical plate, a mounting base is provided at one end of the rotating shaft, a telescopic rod is provided on the edge of the mounting base, and a top block is provided at one end of the telescopic rod; the curved frame is provided on the top of the vertical plate, a dial indicator assembly is provided on the top of the curved frame, a connecting rod is provided at the bottom of the curved frame, a detection head is provided at the bottom of the connecting rod, and the detection head is connected to the dial indicator assembly.

[0004] During use, it was found that when the above device sprays oil onto gears of different specifications, the nozzle position is fixed. When a smaller gear is needed, the distance between the nozzle and the gear is large, which causes the atomized oil to float in the air and result in waste. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a special tool for measuring backlash in side-push transmissions.

[0006] This utility model discloses a special tool for measuring backlash in a side-push transmission, comprising a base plate, columns, and a worktable. Multiple sets of columns are mounted on the top of the base plate, with the tops of each set connected to the bottom of the worktable. The tool also includes a mounting assembly, a detection assembly, and an oil spraying assembly. The top of the worktable is equipped with these three components: the mounting assembly for positioning the gear, the detection assembly for detecting the gear, and the oil spraying assembly for spraying oil onto the gear. The position of the oil spraying assembly is adjustable. In use, the gear is positioned using the mounting assembly, then detected using the detection assembly, and finally, the oil spraying assembly is adjusted to spray oil onto the gear, improving convenience and reducing oil waste.

[0007] Preferably, the mounting assembly includes a vertical plate, a motor, a rotating shaft, a mounting base, a limiting ring, telescopic rods, and top blocks. The top of the workbench has a vertical plate, on which a motor is mounted. A rotating shaft is located at the motor's output end. A mounting base is located at the end of the rotating shaft furthest from the motor. A limiting ring is fitted onto the mounting base. Multiple sets of telescopic rods are circumferentially arranged on the outer wall of the mounting base. Each set of telescopic rods has a set of top blocks at its furthest end from the mounting base. The gear is fitted onto the outer side of the mounting base, and the limiting ring limits the gear's movement. The telescopic rods are extended, causing the multiple sets of top blocks to press against the inner wall of the gear, thus fixing the gear. The motor is then started, causing the rotating shaft to drive the gear for angle adjustment.

[0008] Preferably, the testing assembly includes a guide bar, a top plate, a hydraulic cylinder, a lifting plate, a dial indicator assembly, a connecting rod, and a testing head. Two sets of guide bars are installed at the top of the worktable, with the top ends of both sets connected to the bottom of the top plate. A hydraulic cylinder is mounted at the top of the top plate, and a lifting plate is located at the bottom moving end of the hydraulic cylinder. A dial indicator assembly is mounted at the top of the lifting plate, and a connecting rod is mounted on the dial indicator assembly. A testing head is screwed onto the bottom end of the connecting rod and connected to the dial indicator assembly. According to the gear specifications, the hydraulic cylinder is extended, causing the lifting plate to move the dial indicator assembly, connecting rod, and testing head downwards, allowing the testing head to test the gear and improving testing flexibility.

[0009] Preferably, the oil spraying assembly includes a lead screw, a handwheel, a moving plate, a reservoir, a micro pump, and an atomizing nozzle. A concave groove is provided at the top of the workbench, and a lead screw is rotatably mounted in the groove. One end of the lead screw extends to the outside of the workbench and is fitted with a handwheel. The moving plate slides within the concave groove and is threadedly connected to the lead screw. A reservoir and a micro pump are mounted on the moving plate. The output end of the micro pump extends into the reservoir, and an atomizing nozzle is mounted at the output end of the micro pump. Depending on the gear size, the operator rotates the handwheel, causing the lead screw to move the moving plate to adjust its position. After adjustment, the micro pump is activated, causing the oil in the reservoir to be atomized and sprayed out through the atomizing nozzle to coat the gear. The atomizing nozzle is close to the gear to reduce oil waste.

[0010] Preferably, the device also includes adjustable feet, with a set of adjustable feet provided at each of the four corners of the bottom of the base plate; the four sets of adjustable feet work together to provide stable support for the device and improve its stability.

[0011] Preferably, it also includes a handle, and the top of the workbench is provided with a handle; the staff can move the device by using the handle, which improves convenience.

[0012] Compared with the prior art, the advantages of this utility model are as follows: In use, the gear is positioned by the mounting component, then the gear is detected by the detection component, and then the oil injection component is adjusted to perform oil injection operation on the gear, which improves convenience and reduces oil waste.
