Problems solved by technology

[0010] Another disadvantage of the known technology is manifested in the fact that the production requirements for the different reduction stages selectively used in the planetary reduction gear stage gear train, relative to the torque or speed obtained at the output of the tubular electric motor reducer The reduction stage is selected

Embodiment Construction

[0022] It must be noted that the accompanying figures show a planetary reduction gear formed by three combined stages, each stage having an "inner" mesh at the input and an "outer" mesh at the output. Obviously, it is also possible to equip the input side with the internal snap-in device and the output side with the external snap-in device.

[0023] refer to figure 1 and figure 2 , the planetary reduction gear R is formed by a gear train of three combined stages M1, M2, M3, which are designed to be connected one after the other in any order.

[0024] M1 represents the first stage, ie the stage towards the motor, not shown in the figure, and M3 represents the last stage, ie the stage towards the winding roller of the roller blind, not shown in the figure.

[0025] The combined stages M1, M2, M3 are of the same size and construction, while the gear ratios depend on the size of the gears they contain.

[0026] With reference to Figure 3, each reduction stage is formed by a fi...

Abstract

The present invention relates to an epicyclic reduction gear with multiple modular stages for tubular motor reducers operating winding roller shutters, roller shades and the like. Each reduction stage is provided with a central toothed hub on one side and a central splined hub on the other side, in compliance with the said hub, the hub of a stage being designed to be coupled with a pin of the adjacent stage.

Description

technical field [0001] This industrial invention patent application relates to a multi-stage combined planetary reduction gear for a tubular motor reducer used for winding roller blinds, roller curtains, etc. Background technique [0002] The structural form and operation mode of the tubular motor reducer are standardized. [0003] This type of motor reducer includes a multi-stage combined planetary reduction gear housed in a tubular housing, driven to rotate by an electric motor mounted on an external position of one of the two openings of the tubular housing, and in the following manner Orientation: so that its axis is aligned coaxially with said tubular casing and the pin of the last stage protrudes from the opposite opening for the power take-off. [0004] An adapter directly connected to the roller screen shaft is splined on said pin. [0005] A motor reducer of this type is disclosed in European Patent No. 976909 of the same applicant. [0006] Usually, said planeta...
