Problems solved by technology

For bearings with low clearance in the radial direction, the bushings must be exactly aligned with one another on opposite sides of the rotor shaft and arranged correspondingly precisely in the housing, otherwise there would be increased friction with accompanying heating hazard, which can lead to bearing damage and reduced life

Embodiment Construction

[0030] exist figure 1 shows a starter device 1 for an internal combustion engine, which is embodied as a permanently engaged starter. The starter device 1 comprises an electric starter motor 2 , a transmission 3 and a drive shaft 4 with a starter pinion 5 arranged thereon in a rotationally fixed manner. To start the internal combustion engine, the electric starter motor 2 is started, the drive motion of which is transmitted via the transmission 3 to the drive shaft 4 and the starter pinion 5 , which engages and drives the ring gear of the internal combustion engine.

[0031] The electric starter motor 2 is designed as a permanently excited electric motor and has permanent magnets 7 on the inside of the pole shoes or the stator housing 6 . The starter motor 2 is designed as an inner-rotor motor and has a rotatably mounted rotor shaft 8 in the pole piece 6 with an armature core 9 which, distributed over the circumference, comprises multiple windings. The rectifying device 10 ...

Abstract

The invention relates to a starter device for an internal combustion engine, which has an electric starter motor, the drive movement of which can be transmitted via a transmission to a starter pinion. The rotor shaft of the starter motor is accommodated in a first bearing designed as a radial bearing and in a second bearing, wherein the rotor shaft is supported in both axial directions on a bearing cover on which the second bearing is accommodated middle.

Description

technical field [0001] The invention relates to a starter device for an internal combustion engine with an electric starter motor, the drive movement of which can be transmitted via a transmission to a starter pinion, wherein the rotor shaft of the starter motor is rotatable adjacent its end face are each supported in a bearing, wherein the transmission-side bearing is supported on a bearing cover arranged on the end side of the pole shoe of the starter motor. Background technique [0002] DE 297 04 299 U1 describes a starter device for an internal combustion engine, which has an electric starter motor, the rotor shaft of which drives a starter pinion via a transmission. The rotor shaft carries an armature core with a winding, which is energized via a rectifier. The rotor shaft is rotatably accommodated at its two end faces in bearings, wherein the bearing is on the drive side in a flange supported on a bearing cover arranged on the end face of the pole shoe of the starter ...
