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 device for measuring churning power losses of tooth number variable gears. The device comprises at least a tooth number variable gear train, wherein the tooth number variable gear train comprises a gear disk body, a plurality of gear insert teeth and a plurality of gear tooth slots formed in the circumferential surface of the gear disk body at equal intervals; insert block slots are formed at the two sides of the bottoms of the gear insert teeth respectively; springs I and press blocks are radially arranged inside the gear tooth slots in sequence; two rectangular slots are formed between two adjacent gear tooth slots; the adjacent rectangular slots are communicated with the gear tooth slots; rectangular blocks and springs II are arranged inside the rectangular slots and in the communication positions of the rectangular slots and the gear tooth slots in sequence; and when the gear insert teeth are inserted in the gear tooth slots, the press blocks arranged in the gear tooth slots move downward, the rectangular blocks are inserted in the insert block slots under the actions of the springs II and the gear insert teeth are fixed in the gear tooth slots. The device has the advantages that any number of gear insert teeth can be installed on the gear disk bodies, thus being convenient for changing the tooth numbers of the gears and then studying the impacts of different tooth numbers on the churning power losses.

Description

technical field [0001] The invention relates to a power loss measuring device, in particular to a measuring device and method for oil churning power loss of a gear with a variable number of teeth. Background technique [0002] The current cause of the power loss of the oil stirring mechanism is mainly the research on the external factors 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 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. Contents of the invention [0003] The purpose of the present invention is to provide a measuring device and method for oil churning power loss of gears with variable number of teeth, which is convenient to...
