Problems solved by technology

Unfortunately, the machinability of high manganese steel is very poor. After using it to cast gears, it is impossible to use conventional machining methods to process the inner hole and spline structure that meet the precision requirements of the device.
Therefore, the desire to manufacture high manganese steel gears has not been realized due to the inability to solve the machining problem

Embodiment 1

[0023] This embodiment is a high manganese steel compound casting gear used for mining machinery transmission, as shown in Figure 1 and Figure 2, the gear is composed of a high manganese steel gear outer ring 1 including a tooth profile 6 and a carbon structural steel inner ring 4 is formed by integral casting, and the joint surface 2 of the outer high manganese steel outer ring 1 and the carbon structural steel inner ring 4 is located in the middle of the minimum thickness of the ring gear, which is a metal phase combination formed by casting. The structural steel inner ring 4 is formed with an inner hole with a spline 3 . Since the carbon structural steel has good machinability, the spline structure of the inner hole is formed by machining according to the required precision after casting. Both sides of this gear are shaped on ribs 5 integrally cast with the tooth profile of the high manganese steel gear outer ring 1, which can automatically limit the axial position of the g...

Abstract

A high-Mn steel contained gear is prepared through providing a mould, pouring the molten high-Mn steel in the external toothed ring part of mould, solidifying it while pouring the molten carbon steel or alloy steel in the internal ring part of mould, and solidifying the internal and external rings at same time. Its gear product is also disclosed, which has high anti-impact and anti-wear performance and high machinability.

Description

technical field [0001] The invention relates to a casting method of a composite gear, and simultaneously designs a high manganese steel composite casting gear manufactured by the process, belonging to the technical field of mining machinery transmission. Background technique [0002] The transmission gears of heavy-duty mining machinery work in harsh environments, so they have special requirements for use. According to the applicant's knowledge, the transmission gears used in the existing mine heavy-duty machinery are mainly integrally cast with alloy structural steel or carbon structural steel through traditional techniques, and the tooth shape is directly cast. [0003] In order to meet the special requirements of impact resistance and wear resistance during transmission, heavy-duty transmission gears must have certain toughness and good wear resistance. Therefore, the casted gear needs to undergo heat treatment to obtain sufficient surface hardness after necessary machin...
