Embodiment Construction

[0015] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0016] The first gear 1 and the second gear 3 are a pair of gears, and the detection method for the gear meshing normal clearance is to use such as image 3 Shown measuring device, this measuring device comprises two supporting plates 2 arranged in parallel and a bottom plate 7 connected to the lower parts of the two supporting plates 2, and the first concaves arranged coaxially are arranged on the top surfaces of the two supporting plates 2. Groove 8 and second groove 9; The first groove 8 and the second groove 9 are semicircular grooves arranged in parallel, and the distance between the axes of the two semicircular grooves is the first gear 1 and the second The sum of the pitch circle radii of the second gear 3;

[0017] The gear meshing normal backlash detection method includes the following steps:

[0018] A. Set the first gear 1 and the second gea...

Abstract

The invention discloses a method for detecting gear meshing nominal clearance, and relates to the technical field of mechanical manufacturing. The method for detecting the gear meshing nominal clearance comprises steps as follows: gears are mounted on gear measurement spindles, the gear measurement spindles and the gears are arranged in semi-circular grooves of support plates of a measurement device respectively, a pair of gears is in a meshing state, one gear measurement spindle is fixed, a first gear measurement spindle is slightly rotated to enable a tooth surface of a first gear to touch one tooth surface of a second gear, and at the moment, reading I is obtained by a measurement dial gauge; then the tooth surface of the first gear touches the other tooth surface of the second gear, reading II is obtained by the measurement dial gauge, and a nominal clearance value of the first gear and the second gear is obtained through subtraction of the reading I and the reading II. Compared with the prior art, the problems of time and labor consumption, inaccurate measurement and higher measurement cost of conventional gear meshing nominal clearance measurement can be solved.

Description

technical field [0001] The invention relates to the technical field of mechanical manufacturing, in particular to a method for measuring the normal clearance when a pair of gears mesh. Background technique [0002] When designing and developing a new product, the size or value range of the normal gap (meshing gap) after the meshing of the paired gears often affects the performance of the product. At present, the measurement of the normal gap of the paired gears is generally The method of measuring the thickness of the lead wire after placing the lead wire between the teeth, or using a feeler gauge to fill the gap between the teeth, these two methods are time-consuming and laborious and the measurement is inaccurate; the other method is to use three coordinates Measuring instrument to measure, but this method needs to invest a lot of money, and the measurement is time-consuming, and the cost is not cost-effective. Contents of the invention [0003] The purpose of the prese...
