Problems solved by technology

There is no special reducer mechanism that can change the number of gear teeth, position and direction of rotation. The number of teeth, position and direction of rotation are generally fixed when measuring power loss, and the influence of changes in the number of teeth on the oil churning power loss of the reducer is ignored. These factors may affect the oil churning main cause of loss

Abstract

The invention discloses a measuring device for oil churning power loss of a variable number of teeth gear, which is characterized in that it comprises at least one gear set with a variable number of teeth. The wedge-shaped tooth slots on the side of the gear disc body, the springs and pressing blocks arranged inside each wedge-shaped slot along the radial direction, and several wedge-shaped slotting teeth arranged on the peripheral side of the gear disc body; A square opening is provided on the wedge-shaped tooth groove and on the circumferential surface of the gear plate body, and the pressing block is pressed down radially, and the wide part of the wedge-shaped tooth is inserted into the wedge-shaped tooth slot from the side of the gear plate body. In the tooth groove, the wedge-shaped slotting tooth is fixed under the action of the spring restoring force and the friction force between the contact surfaces on both sides of the wedge-shaped tooth groove; The influence of position and different steering on the oil churning power loss of the reducer.

Description

technical field [0001] The invention relates to a power loss measuring device, in particular to a variable tooth number gear oil churning power loss measuring device and a method thereof. Background technique [0002] At present, the reason for the power loss of the oil stirring mechanism is mainly the research on the external cause of the power loss of the oil stirring mechanism. There is no special reducer mechanism that can change the number of gear teeth, position and steering. When measuring power loss, the number of teeth, position and steering are generally fixed, ignoring the influence of changes in the number of teeth on the power loss of reducer oil churning. These factors may all affect the oil churning. main reason for the loss. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a variable-tooth gear oil churning power loss measuring device and its method, which is convenient for changing the gear tooth number, position and st...
