Problems solved by technology

Gear finishing is done after quenching, generally by mechanical grinding, such as grinding machine grinding, so the finishing of quenched gears requires superhard tools, and the cost of tools is high
Commonly used gear finishing methods cannot be completed with ordinary tools and ordinary processing parameters
Milling is often used instead of grinding and finishing on high-precision multi-axis CNC milling machines, and the surface quality of milling is not high

Embodiment Construction

[0038] Such as Figure 1 to Figure 8 as shown,

[0039] The box body 1 is the installation base of other parts, which is a rectangular groove, which can be formed by welding steel plates or stainless steel plates. The first gear shaft fixing and adjusting assembly and the second gear shaft positioning assembly are installed on the two side walls. The two gears It is installed inside, and its inner cavity contains oil and abrasive mixture, and a box cover can be fastened on the upper part of the box to prevent the internal liquid from overflowing. It is the supporting part of the whole device. The left and right side walls of the box body 1 are all provided with elongated holes 11 and shaft holes 12, wherein the elongated holes are used to install the first gear shaft, and the shaft holes 12 are used to install the second gear shaft. , the two gear shafts are parallel to each other. Two of the gears to be finished are respectively fixed on the first gear shaft and the second ...

Abstract

The invention discloses a gear finish machining device used for solving the problem that gear machining precision is not high. The gear finish machining device comprises a box body, a first gear shaft fixing and adjusting assembly and a second gear shaft locating assembly. Oil liquid and grinding material mixture are contained in an inner cavity of the box body. The two ends of a first gear shaft are fixed in the first gear shaft fixing and adjusting assembly through bearings. The first gear shaft fixing and adjusting assembly comprises bearing cover plates, the bearings, sliding bearing seats, sealing gaskets, locating screws, and a spring jack beam mechanism. The second gear shaft locating assembly comprises bearing assemblies, gaskets and bearing end covers. The two side walls of the box body are provided with shaft holes. The bearing assemblies, the gaskets and the bearing end covers are sequentially fixed on the sides walls, where the shaft holes are located, of the box body. According to the gear finish machining device and method, a gear is contacted with grinding materials, the generating cutting principle is adopted for grinding machining, and the surface roughness Ra value at least can reach the surface precision of 0.01 nanometer.

Description

technical field [0001] The invention relates to the technical field of gear finishing, in particular to a gear finishing method and a gear finishing device. Background technique [0002] Gear transmission mechanisms are often used in automation equipment, which have high requirements for shape, size, and surface quality, and need to be finished. In order to improve the motion accuracy, wear resistance and service life of the gear, it is necessary to quench the gear to increase its hardness. Gear finishing is completed after quenching, generally by mechanical grinding, such as grinding machine grinding, so the finishing of quenched gears requires superhard tools, and the cost of tools is high. Commonly used gear finishing methods cannot be completed with ordinary tools and ordinary processing parameters. Milling is often used instead of grinding and finishing on high-precision multi-axis CNC milling machines, but the surface quality of milling is not high. For occasions re...
