Problems solved by technology

[0002] The reducer is a common force transmission device. Under working conditions, the reduction gear needs to carry different forces according to the size of the driving load, and long-term work will lead to the phenomenon of fracture and wear of the reduction gear. The existing reducer is in the It is difficult to replace the gears. It is necessary to disassemble the entire housing and disassemble the entire transmission shaft. Due to the many interference factors in the coordination of internal parts, the maintenance of the reducer is difficult and the maintenance efficiency is low.

Embodiment 1

[0016] Example 1: see Figure 1-Figure 3 , A speed reducer that is convenient for gear replacement, including a housing, 1, two drive shafts arranged side by side in the housing 2, an input shaft 3 arranged perpendicular to the drive shaft 2, an input shaft 3 and one of the drive shafts 2 A set of transmission bevel gears 4 between the two transmission shafts, and a set of reduction gears 5 set between the two transmission shafts. The housings at both ends of the transmission shaft are provided with through holes, and the through holes are provided with supports The end cover 6, the outer end of the support end cover 6 and the housing 1 are fixedly connected by bolts, and a support bearing 7 is provided between the inner end of the support end cover 6 and the transmission shaft. The transmission shaft includes a left half shaft 21 and The right half shaft 22, the left half shaft 21 and the right half shaft 22 are all provided with a connecting flange 8 and are fixedly connected...

Embodiment 2

[0017] Embodiment 2: In this embodiment, in order to ensure the effective transmission of the torque of the drive shaft and reduce the shear stress on the bolts, the left half shaft and the right half shaft are respectively provided with matching positioning grooves 10 and positioning posts 11 in the axial direction. The outer wall of the positioning column 11 is provided with a plurality of torque transmission ribs 12 on the circumference, and the inner wall of the positioning groove is provided with a force-bearing groove 13 corresponding to the torque transmission rib.

[0018] The structure of the present invention is reasonable and compact. Through the design of the transmission shaft, the transmission shaft can be effectively split, thereby ensuring that when one of the gears on the same transmission shaft is damaged, it can be quickly disassembled and assembled for timely Replacement greatly reduces the difficulty of maintenance, effectively improves maintenance efficiency,...

Abstract

The invention belongs to the technical field of speed reducers. The invention discloses a speed reducer with convenient gear replacement. The speed reducer comprises a shell, two transmission rotation shafts which are arranged in the shell side by side, an input rotation shaft which are perpendicular to the transmission rotation shafts, a group of transmission bevel gears which are arranged between an input rotation shaft and one transmission rotation shaft, and a group of speed reducing gears arranged between the two transmission rotation shafts. The shell at two ends of the transmission rotation shaft is provided with through holes which are internally provided with support end covers, and supporting bearings are arranged between the inner ends of the support end covers and the transmission rotation shaft. The transmission rotation shaft comprises a left half rotation shaft and a right half rotation shaft. Both the left half rotation shaft and the right half rotation shaft are provided with connection flange disks and are fixedly connected through bolts. The speed reducer has a reasonable and compact structure design and can be rapidly dismounted, the timely replacement is carried out, the maintenance difficulty is greatly reduced, the maintenance efficiency is effectively improved, and the production cost and maintenance cost can be reduced.

Description

Technical field [0001] The invention belongs to the technical field of speed reducers, and in particular relates to a speed reducer that facilitates gear replacement. Background technique [0002] The reducer is a common force transmission equipment. Under working conditions, the reduction gear needs to carry different forces according to the size of the driving load, and long-term work will cause the reduction gear to break and wear. The existing reducer It is difficult to replace the gears. It is necessary to dismantle the entire housing and the entire transmission shaft. Due to the many interference factors in the cooperation of internal parts, the maintenance of the reducer is difficult and the maintenance efficiency is low. Summary of the invention [0003] In view of the above-mentioned existing problems and shortcomings, the present invention provides a reducer with reasonable and compact structure design, good transmission effect, stable performance, and convenient assembl...
