JPH0211964A - Epicycloid gear box having no separate adaptation outlet shaft support bearing - Google Patents

Abstract

PURPOSE: To change the installing position of a gear box assembly on a speed reducer without completely dismantling an assembly of the gear box and speed reducer by performing the installation of the gear box assembly using a shaft protruding outward of a separately adapted male piece. CONSTITUTION: Through a bushing 6, a satellite group 3 pulls a satellite holding plate 7 key fastened by a tab part 8 of a shaft 9 of speed reducer, and thus the shaft 9 revolves in angular rotation. The speed is adjusted by acting on a pivot 10 using a control screw. For mounting a gear box-speed reduce assembly, a coupling cover 11 is provided on the speed reducer and combination is made. In mounting, a locating screw 12 to fix the satellite disc 7 in the axial direction is previously provided and coupling can be established through a simple installing operation. This condition is accomplished by inserting a speed converter to the shaft 9 of the speed reducer and by fixing the flange coupling with screw.

Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) This invention relates to an epicycloid gear box that is directly connected to a speed reducer through a male protruding speed shaft. The invention allows the gearbox assembly to be installed separately to suit the mode of use without having to completely remove the converter and reducer assembly.

Continuous reducers are almost always coupled with worm reducers or gears, i.e. to obtain relatively low rotational speeds, and
This is to meet different usage requirements in several applications.

(Prior Art) At present, the connection with the reducer is carried out by combining the gear box with the outlet flange, and the shaft protruding outside the reducer with a hollow shaft and a worm gear or gears. This is as predicted by the combination of machines.

OBJECTS AND MEANS FOR SOLVING THE PROBLEMS The present invention improves the structure and fit by directly attaching the gear box assembly to the reducer with another matched male outwardly projecting shaft. Performing simplification and abbreviation.

Therefore, it is possible to change the mounting position of the reduction gear with respect to the gear box without completely removing the assembly of the gear box and the reduction gear. This method provides two advantages:
That is, only one line of ball bearings is used instead of four lines as in this model, and economic advantages are obtained since the reducer is used without radial ball bearings etc. It is. To support the outlet hollow shaft, two bromate rings 13 and 14 are used which define its positioning radially along the satellite of the same transducer, at α-height. During installation, the axial positioning of the satellite disc is ensured by a longitudinal screw fitted into the inlet cover, which screw is removed when the transducer is installed in operation 5.

Due to the flankless connection, each part of the converter now has to be assembled separately into the reducer, resulting in an original assembly that can no longer be modified.

Is this an inherent disadvantage since it is not possible to use a gearbox assembly if a change in style is required with proper removal of the converter relative to the transmission location?
arise.

The invention makes it possible to solve the problem by making it possible to use a separate gearbox that allows for stylistic variations without forcing a complete disassembly of the converter and gearbox group.

(Example) The transmission gear box is connected to the outer ring 4 through a bundle of berebu washers 2.
It consists of a drive disk l sandwiching satellite #3 which rotates between the two wheels. Via the bushings 6, these satellites pull on the satellite holding disc 7, which is keyed by the tongue 8 of the reducer shaft 9, which is thus turned in an angular rotation. The speed is adjusted by acting on the pivot 10 by means of a control screw. To install the gear box reducer assembly, a coupling cover 11 is provided and assembled to the reducer. At the time of attachment, positioning screws 12 for fixing the satellite disk 7 in the axial direction are arranged in advance, so that the connection can be made by a simple attachment operation.

This condition can be achieved by inserting the speed converter into the shaft of the speed reducer and fixing the joint of the 7/8 with screws. Before installing the converter and reducer di-assembly into operation, the screw 12 is removed and the conventional closure plug 15 is installed.
Replace with

Grommet rings 13 and 14 may alternatively be replaced with a stiff self-lubricating pump 7 to provide additional radial stiffness to the exit hollow shaft of the speed IA machine.

When implementing this device, the components can also be used in different ways and utilized according to different usage requirements.
