Abstract:
The invention relates to a method for manufacturing a propeller reduction gear, which comprises the following steps: measuring manufacturing defects of the casing (∆Yav, ∆Zav, ∆Yar, ∆Zar); calculating a first angular play (δfabrication) induced at each intermediate gear (2a, 2b) by the measured manufacturing defects (∆Yav, ∆Zav, ∆Yar, ∆Zar); estimating a second angular play (δdéformation) induced at each intermediate gear (2a, 2b) by deformations of the casing (12) when the reduction gear transmits a threshold torque; calculating a total angular play (δtotal) from the first angular play and the second angular play; and selecting two intermediate gears with a phase difference (-δtotal) that compensates for said total angular play.
Abstract:
According to one exemplary embodiment of the present invention a worm shaft subassembly (60) for supporting a worm shaft (50) is provided. The worm shaft has a worm shaft radial load, a worm shaft axial load, and a worm shaft axial travel. The worm shaft subassembly includes at least one damping member (76) to support the worm shaft axial load. The at least one damping member has at least one damping member axial load. The at least one damping member limits the worm shaft axial travel. The worm shaft subassembly also includes a bearing (72) to support the worm shaft radial load and the at least one damping member axial load.
Abstract:
A drive unit for automotive applications, specifically for application with or in combination with a motor vehicle door lock, a housing (5), a motor (1) as well as an associated motor shaft (2), and with at least one spring element (6) generating an axial force at one end of the motor shaft (2), with the spring element (6) being located in at least one receptacle (7, 8) in the housing (5). In a top view, the spring element (6) has essentially a T-shaped design with an end plate (6a) and cantilevers (6b) on both sides, with the end plate (6a) acting upon the motor shaft (2), and at least the cantilevers (6b) being arranged in the receptacle (7, 8).
Abstract:
An adjustment tool (300) is disclosed herein. For example, an adjustment tool (300) is provided comprising an input gear (302) having gear teeth (316) and an output gear (304) having gear teeth (318), wherein the input gear (302) and the output gear (304) are in meshed engagement, an input shaft (306) centrally coupled to the input gear (302), wherein the input gear (302) is configured to rotate about the input shaft (306), and a housing (312) supporting the input shaft (306) for rotation and supporting a fastener, wherein a tooth (318) of the output gear (304) protrudes from the housing (312).
Abstract:
A method of deriving a path of contact of a face gear with a pinion gear includes positioning the pinion gear, shifting the pinion gear from either towards or away from the face gear along a rotational axis, deriving a first relationship between a rotational angle of the pinion gear and a fluctuation error angle, deriving second and third relationship by shifting the first relationship in either way for 360 degree divided by the number of the gear teeth, deriving a first point which the first and second relationships share and a second point which the first and third relationships share, deriving a third point, at which the fluctuation error is the same as the first and second points, between the first and second points, and determining a curve line on tooth flanks of the gear teeth on the basis of the first, second, and third points.
Abstract:
An adjusting gearing for an adjusting device of a motor vehicle is provided. The adjusting gearing having a gearing housing, having a drive input wheel which is arranged in the gearing housing and which has bearing collars formed at both sides of the drive input wheel, and having a drive output wheel which is arranged in the gearing housing and which meshes with the drive input wheel and the axis of which is aligned substantially perpendicular to the axis of the drive input wheel. The adjusting gearing further comprising a single part gearing housing having a first housing chamber for holding the drive input wheel and having a second housing chamber for holding the drive output wheel, a bearing point which is formed in the first housing chamber and which serves to hold a first bearing collar of the drive input wheel and a bearing point which is formed in the second housing chamber and which serves to hold a first bearing collar of the drive output wheel, and axially adjustable bearing bushes having cylindrical bushes, which are matched to the inner diameters of the housing chambers for centering second bearing collars of the drive input wheel and of the drive output wheel.
