Embodiment Construction

[0010] see figure 1 A reducer formed according to the invention, generally designated 1, comprises a housing 2 in which is at least partially housed a first reduction stage and a second reduction stage, designated 3 and 4, respectively.

[0011] The second reduction stage 4 comprises a pair of spur gears 5,6 with parallel axes X,Y, mounted intermeshingly and keyed to respective tubular shafts 7,8. The shaft 7 constitutes the main drive output shaft of the reducer, is supported on bearings 7a, 7b, and is hollow to allow vibration mounting of the reducer 1 if required.

[0012] The shaft 8 constitutes the drive input shaft belonging to the second stage of the reducer, which is also hollow and has an enlarged diameter interior 10 at a first end 11 .

[0013] The enlarged diameter interior 10 at least partially accommodates a coupling 13, such as a cassette coupling, which is keyed to a drive shaft 14 of an electric motor 15 which in turn is connected by means of a flanged coupli...

Abstract

A reducer, which includes at least a first reduction stage and a second reduction stage (3, 4), wherein the second reduction stage (4) has a plurality of cylindrical gears (5, 6) with parallel axes Drive input and output shafts (8,7), and the drive input shaft (8) of the second reduction stage (4) is hollow and coaxially accommodates a drive input shaft (17) of the first reduction stage (3) , the first reduction stage (3) is arranged at one end of the hollow shaft (8) axially away from the installation position of the motor (15).

Description

technical field [0001] The object of the invention is a gear unit of the type comprising at least one first reduction stage and one second reduction stage, in which the second stage has a plurality of spur gears with drive input and output shafts parallel to the axes. technical background [0002] The term "reducer" is used herein in the most general sense of a transmission which can be manipulated to reduce or increase the relative speed of a main drive input shaft and a main drive output shaft. A reducer comprising the features listed above is known under the term "CYCLO MODULAR SYSTEM" and produced by Sumitomo Cyclo Drive Burope Ltd. [0003] This CYCLO transmission system is particularly useful when it is necessary to use high reduction ratio reducers with parallel or perpendicular axes. And it's great for vibrating installations. CYCLO reducers consist of a first cycloidal reduction stage combined with a second reduction stage with parallel axes and have a hollow driv...
