The embodiment of the invention discloses a gearbox. The gearbox comprises a box body, and further comprises a box cover and a shifting fork assembly, wherein the box cover is installed above the boxbody, and an assembly and disassembly opening is formed in the box cover; the shifting fork assembly comprises a shifting fork base and a shifting fork main body, the shifting fork base is mounted atthe assembly and disassembly opening, and the shifting fork base is movably and detachably connected with the box body; and the shifting fork main body is located right below the assembly and disassembly opening, the shifting fork main body is detachably connected with the shifting fork base, a shifting fork block is arranged on the shifting fork main body, and the shifting fork block is connectedwith a gear shifting gear to drive the gear shifting gear to slide in an axis direction of an output shaft. Due to the fact that the assembly and disassembly opening is formed in the box cover, the shifting fork base is installed at the assembly and disassembly opening, when a shifting fork needs to be replaced, the box cover does not need to be disassembled, only the shifting fork base needs tobe disassembled, the shifting fork base and the shifting fork main body are taken out, then the shifting fork main body is disassembled from the shifting fork base for replacement, so that the time for replacing the shifting fork of the gearbox is shortened.
Description
technical field [0001] The invention relates to the field of transmission structures, in particular to a gearbox. Background technique [0002] The gearbox plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator, and is widely used in modern machinery. In steel and non-ferrous metal rolling equipment, in order to better meet the process requirements and improve the working capacity and economy of the prime mover, the gearbox is often designed with a variable speed ratio structure, and the total speed ratio of the low gear is large to meet The working requirements of extremely large torque and low speed, while the overall speed ratio of high gear is small to meet the working requirements of low torque and extremely high speed [0003] In order to switch between low gear and high gear, a shifting device is required. The usual method is to use the oil cylinder to drive the rotary arm to rotate the transmission shaft,...
