摘要

#CMT# #/CMT# The helical bevel gear (100) has a screw bevel (103) connected with a drive shaft of an electrical driving motor. The screw bevel is arranged in a transmission case and stands in contact with a bevel gear (104). A preload device is provided for improving the contact to impinge the screw bevel radially with a prestressing force. A tiltably arranged sleeve (120) is provided in the transmission case in which the screw bevel is stored. The preload device directly acts on the sleeve. #CMT#USE : #/CMT# Helical bevel gear, particularly worm gear for an electrical power steering for motor vehicle (Claimed). #CMT#ADVANTAGE : #/CMT# The screw bevel is arranged in a transmission case and stands in contact with a bevel gear, and hence ensures rotating movement of the screw bevel perpendicularly to the axis of rotation. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a perspective cross-sectional view of a helical bevel gear. 100 : Helical bevel gear 103 : Screw bevel 104 : Bevel gear 120 : Sleeve 121 : Bearing stud.
