An easy-to-maintain coaxial mechanical gearbox

Abstract

The invention relates to a gearbox, in particular to an easy-to-maintain coaxial type mechanical gearbox in the field of forklifts. The easy-to-maintain coaxial type mechanical gearbox has the following technical scheme that the easy-to-maintain coaxial type mechanical gearbox comprises a motive power input shaft and is characterized in that the motive power input shaft comprises a motive power input shaft bearing cover, a motive power input shaft sliding shaft, an input shaft gear sleeve and fixing screws, and the fixing screws can be used for detachably connecting the input shaft bearing cover, the input shaft gear sleeve and the motive power input shaft sliding shaft. The practical function of a speed raising and changing system can be improved, and the goals of great output torque, flexible and portable gear shifting, safety, reliability and compact structure are reached. Particularly, the input end structure is reformed, the controllable free extension and retraction of the input shaft can be realized, the problem of difficulty in clutch part replacement is solved, when quick-wear parts such as release bearings and friction plates need to be replaced, the fixing screws are loosened, the motive power input shaft sliding shaft can freely retract into the input shaft gear sleeve along an involute spline groove, the sufficient space is formed, and the quick-wear parts such as the release bearings and the friction plates can be conveniently dismounted.

Description

technical field [0001] The invention relates to a gearbox, in particular to an easy-to-maintain coaxial mechanical gearbox used in the field of forklifts. Background technique [0002] At present, the mechanical gearboxes used by domestic 4T-5T industrial forklifts generally have defects such as small transmission torque, difficult shifting, and loud noise; especially the release bearings and friction plates in the clutch device installed at the input end of the gearbox are vulnerable. It is cumbersome to replace parts and difficult to maintain. The heavy engine and gearbox must be disassembled to be removed. This problem has plagued users and maintenance personnel for a long time, and has limited the development space for the practical application of this type of forklift. Contents of the invention [0003] The purpose of the invention: in order to provide convenient transmission, especially an easy-to-maintain coaxial mechanical gearbox. [0004] In order to achieve the...
