Description

Driven bevel gear of split structure Technical Field The utility model relates to the technical field of passive bevel gears, in particular to a passive bevel gear with a split structure. Background In the field of mechanical transmission, bevel gear transmission is widely applied to a plurality of mechanical devices such as universal reducers (dby series, dcy series and the like) by virtue of the remarkable advantages of high reversing, high overlap ratio, stable transmission, low noise, high bearing capacity and the like. The passive bevel gear is used as a key component in a bevel gear transmission system, and the performance and the structural design of the passive bevel gear play a critical role in the operation effect of the whole transmission system. At present, chinese patent application number 202222002084.5 discloses a split type gear for speed reducer, wholly split the gear into two semicircular gears, set up fixture block and draw-in groove that can block each other on two semicircular gear faying surfaces respectively to through bolted connection two semicircular gears, need not dismouting transmission shaft whole when changing the gear, improved the convenience of operation and reduced repetition installation error, but only through two bolted connection between two semicircular gears, in the speed reducer operation in-process, the bolt drops easily, and the circumference force between two semicircular gears makes the bolt wearing and tearing warp, cut even easily, causes the connection inefficacy. Disclosure of utility model Technical problem to be solved Aiming at the defects existing in the prior art, the utility model provides a driven bevel gear with a split structure, which can effectively solve the problems in the prior art. Technical proposal The utility model provides a driven bevel gear with a split structure, which comprises a left block and a right block, wherein the left block and the right block are fixedly connected through splicing, annular tooth grooves and front threaded holes are formed in the front ends of the left block and the right block, a front end fixing frame is fixedly inserted into the annular tooth grooves, the front end fixing frame is meshed and fixed with the front threaded holes through a front threaded rod, a rear annular groove is formed in the rear ends of the left block and the right block, rear threaded holes are formed in the rear annular groove, a rear end fixing frame is placed in the rear annular groove, and the rear end fixing frame is meshed and fixed with the rear threaded holes through thick bolts and thin bolts.
