Problems solved by technology

For flexible gears, fluorine rubber components are generally added to the web, which will have more restrictive requirements on the use conditions of the system and also limit the service life of the system; for flexible shafts, since they are generally connected by splines, This has requirements for the number of teeth of the spline and the number of teeth of the gear, and it is not easy to install

Abstract

The invention discloses a branch torque transmission mechanism for speed reduction. The mechanism comprises an input device, an output device, a transmission system I and a transmission system II; the input device comprises a power input shaft and an input drive gear; the output device comprises a power output shaft and an output driven gear; the transmission system I comprises a flexible shaft I, an input driven gear I, a middle shaft sleeve I and an output drive gear I; the transmission system II comprises a flexible shaft II, an input driven gear II, a middle shaft sleeve II and an output drive gear II; the input driven gear I and the input driven gear II are arranged at intervals, and the output drive gear I and the output drive gear II are arranged at intervals. The branch torque transmission mechanism is light, large in transmission ratio, compact in structure, high in bearing capability and easy to machine; the transmission torques of gears of branches are reduced, the bearing capability of the gears are improved, the fatigue lives of the gears are prolonged, the average load performance of the mechanism is improved, and the assembling difficulty of the mechanism is lowered.

Description

technical field [0001] The invention belongs to the field of speed reducers, and in particular relates to a split torque transmission mechanism for speed reduction. Background technique [0002] Compared with the planetary transmission system, the cylindrical gear split torque transmission system has obvious advantages in terms of reliability, weight, reduction ratio, noise, etc., but there are few examples of this system in the past. This is mainly because this design has long been considered to be risky, because even a small manufacturing and installation error will cause a large change in the distributed load of the two branches, resulting in the gear life not meeting the requirements, or even rapid failure. There is a premise to make full use of the advantages of the cylindrical gear split torsion transmission system, and this premise is that the loads of the two branches must be evenly distributed. [0003] At present, the load sharing methods of split torsion transmis...
