Abstract

the solution relates to a worm gearbox a reducer arranged between the inlet neck and a rolling inner jacket. The purpose is to shorten the entire gearbox by removing it classic output shaft which is achieved by incorporating the mounted the hub into the flexible toothed cavity wheels and their concentric fixed connection with the bottom of the inner casing gearbox.

Description

BACKGROUND OF THE INVENTION The present invention relates to a gearbox with a worm reducer arranged in addition to an input shaft and a rolling inner bearing.

[0003] There are known constructional solutions of the gearboxes whose cylindrical lined inner casing is coaxially connected to a flexible toothed wheel and an output shaft of a conventional design, which protrudes from the bottom of the inner casing mounted in the inner diameter of the outer casing The knees, or the inner casing is coaxially connected to the resilient toothed wheel, by means of a stepped pin and from the outer casing projecting surface of the inner casing are toothed or grooved to transfer the rotating nonent. A similar solution is a transmission whose roller-mounted outer casing is coaxially connected to a resilient toothed knee and output shafts of a conventional design which protrudes from the bottom of a roller-mounted outer casing to a wijijin diameter of the inner casing surrounding the flexible gear casing and connected with a fixed · toothed gearbox elbow, or the outer casing of the gearbox is coupled to the elastic gear wheel by means of a stepped pin, and the outer surfaces of the roller bearing outer casing are toothed · grooved · provided for transmitting a rotating nonent.

A drawback of design solutions whose rolling housings are adapted to transmit torque is that it is necessary to suitably adjust the input of the driven machine for coupling to the transmission in question.

These drawbacks are avoided in a wave reducer gearbox whose rotatably mounted inner housing surrounds the flexible gear housing and is supported by bearings in the inner diameter of the outer housing, further coupled to the fixed gear, according to the invention by incorporating a stepped The fitted hub allows torque transmission and its placement in the flexible gear cavity removes the conventional output shaft and shortens the transmission to the minimum possible, limited by the length of the flexible gear. Another advantage is the possibility of connecting the gearbox to the driven machine by sliding it onto the input shaft of the driven machine.

Since the outer casing does not rotate, its covering from the point of view of work safety is not necessary, which is another advantage of the solution.

An exemplary embodiment of a wave reducer according to the invention is shown in the drawings where its embodiment is shown in longitudinal section in Fig. 1 and Fig. 2 is a partial front view of the output shaft hub.

The transmission X consists of a wave generator 2 mounted on the input shaft χ, the motor 6, a fixed gear X and a flexible gear 6, in which cavity 2 is a stepped hub 10 provided with a groove 22. 6 and through the bottom X

1 with a rolling sleeve 8 which surrounds the sleeve 60 of the sprocket 6 and are mounted thereon, expanding the sleeve JX and securing the retaining ring JX with bearings, and are inserted into the inner diameter 16 of the outer sleeve JX connected by bolts J6 with fixed gear around X and transition flange 17. engine £, gearbox χ. The bearing space is secured by a locking ring 18 and closed by a duster 18.
