Abstract

The invention relates to a bevel gear assembly gap measuring device which comprises a casing, a measuring mechanism and a fixing mechanism. Supports of the measuring c and the fixing mechanism are installed on the casing, the middles of the supports are provided with hollow adjusting swivel nuts through threads, gear shafts are installed on the casing and penetrate through the adjusting swivel nuts, measuring arms are further fixed on the gear shafts of the measuring mechanism, numerical reading plates are arranged on the supports, and a mechanism for fixing the gear shafts is further arranged on the support of the fixing numerical reading. By designing a fixing system and a measuring system and arranging springs on two sides of each adjusting swivel nut, bidirectional variable-value stress application of a bevel gear pair is achieved, force application is jointly ensured to be achieved according to assembling technological requirements, and the requirements for fixing and gap measurement during the bidirectional variable-value stress application of the bevel gear pair are met.

Description

technical field

[0001] The invention relates to a measuring device, in particular to a bevel gear assembly backlash measuring device. Background technique

[0002] Bevel gear pairs are widely used in transmission systems because they can change the transmission angle, especially in the aviation field, where a large number of bevel gear pairs are used. The assembly backlash of the bevel gear pair is related to its transmission stability and reliability in use. Therefore, it is sometimes required to measure the backlash of the bevel gear pair during assembly to ensure the stability and reliability of use. The assembly measurement of the bevel gear pair includes the measurement of the backlash after the two-way variable value force is added, that is, to apply a force to the matching pair of bevel gear pairs to make the two gears disengage the meshing direction, and measure the maximum value of the backlash. Apply a force to a matched pair of bevel gear pairs to make the two ge...
