Description

Technical Field

[0001] The utility model relates to the technical field of meshing accuracy detection, in particular to a reducer meshing accuracy detection device. Background Art

[0002] A reducer is an independent component consisting of a gear transmission, worm transmission, or gear-worm transmission enclosed in a rigid housing. It is often used as a reduction transmission device between the prime mover and the working machine. It plays the role of matching the speed and transmitting the torque between the prime mover and the working machine or the actuator. It is widely used in modern machinery. Reducers are generally used for low-speed and high-torque transmission equipment. The power of the electric motor, internal combustion engine or other high-speed operation is reduced by meshing the gear with a small number of teeth on the input shaft of the reducer with the large gear on the output shaft. Ordinary reducers will also have several pairs of gears with the same principle to achieve the ideal reduction effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.

[0003] Gears are one of the important parts in machines and instruments, and are often used to transmit various motions and powers. However, due to the complex shape of gears and the large number of geometric parameters, certain errors will occur during production and installation. In order to meet the use requirements of gears, gears must be measured. Double-sided meshing measurement of gear errors is to indirectly feedback the machining error of the gear being measured by checking the change in the gear center distance when the gear being measured and the ideal and accurate measuring gear are meshed without side clearance.

In addition, since the gear to be tested is rigidly mounted on the spindle of the fixed pallet table, the gear to be tested is easily stuck on the spindle, which affects the rapid disassembly and assembly of the gear to be tested and reduces the detection efficiency.
