Problems solved by technology

Appropriately possible, by means of corresponding tolerances of the outer diameter of the eccentric bushing and / or the diameter of the hole at the mounting, an attempt is made to reduce the force of the press fit so that a lower torque is required for rotating the eccentric bushing, but such Tolerances or their implementation and monitoring involve relatively high outlays from cost and manufacturing

Embodiment Construction

[0072] Identical elements or elements with the same function are identified by the same reference numerals in the figures.

[0073] figure 1 and 2 A windscreen wiper motor 10 according to the invention is shown, for example for use inter alia in the actuation of a wiper linkage (not shown). The windscreen wiper motor 10 comprises a drive motor 11 which is in the form of an electric motor and which can be flange-mounted on a housing 12 of the windscreen wiper motor 10 for accommodating a transmission (not shown in detail). The transmission serves to reduce the rotational speed of the drive motor 11 while increasing its torque.

[0074] Out of the top side of the housing 12 protrudes the upper end of the shaft 13 on the outer circumference of which splines 14 are formed. By means of the spline 14, the rod 23 (only in the image 3 shown in ) is rotationally mounted on the shaft 13 so that when the shaft 13 rotates in the direction of the double arrow 16, the rod 23 moves conc...

Abstract

The invention relates to a windscreen wiper motor (10), having a housing (12) for accommodating a gearing arrangement which comprises a gear wheel (20) rotatably mounted in a shaft (13), which gear wheel has, on its outer circumference, a toothing (21) which interacts with a counterpart toothing (19) on a drive shaft (15), wherein the shaft (13) is received in a mount (22; 22a to 22c), which is constructed as a bore, of the housing (12) in an eccentric bush (25; 25a to 25c) for setting the distance (a) between the shaft (13) and the drive shaft (15), and wherein a press fit is formed at least in regions between the mount (22; 22a to 22c) and the eccentric bush (25; 25a to 25c).

Description

technical field [0001] The invention relates to a windscreen wiper motor according to the preamble of claim 1 , as is known, for example, from the applicant DE 10343168 A1. Background technique [0002] Known windscreen wiper motors have a housing for accommodating the transmission, into which housing the armature spindle of the electric motor protrudes in a manner known per se. In the housing, a single or multi-stage transmission is provided, comprising a bull or spur gear rotatably mounted in a shaft. The bull gear has teeth on its outer circumference which mesh with corresponding teeth formed on the armature spindle of the electric motor. The shaft is received within an eccentric bushing which in turn is disposed in the through hole of the housing forming an interference fit. By means of the eccentric bushing, the axial distance between the teeth of the armature mandrel and the shaft can be adjusted during and / or after assembly of the transmission. In this way, the pit...
