#CMT# #/CMT# The device has a machine part (2) that is supported with a bearing inner ring (6), a bearing outer ring (7) and rolling bodies arranged between the inner and outer rings on an axle (4) over a roller bearing e.g. angular ball bearing. Freely moving mass-balancing gears (15) are arranged in an annular cavity and balance an unbalanced mass by taking a counter bearing. The roller bearing is formed as two-rows, where one row of one rolling body is exchanged by the mass-balancing gears such that a single-piece unit is formed from the cavity, the gears and the rolling bodies. #CMT#USE : #/CMT# Device for automatically balancing a rotating part of a machine e.g. washing machine and portable grinder. #CMT#ADVANTAGE : #/CMT# The roller bearing is formed as two-rows, where one row of one rolling body is exchanged by the mass-balancing gears such that the single-piece unit is formed from the cavity, the gears and the rolling bodies, thus manufacturing the device with less complexity and reducing designed space of the device. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The drawing shows a cross-sectional view of a device for automatically balancing a rotating part of a machine. 2 : Machine part 4 : Axle 6 : Bearing inner ring 7 : Bearing outer ring 15 : Mass-balancing gears #CMT#METALLURGY : #/CMT# The rolling bodies are made of chromium steel, and mass-balancing gears are made of copper-tin alloy. |
