Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] Such as Figure 4-5 As shown, the present invention provides a method for adjusting the meshing clearance of bevel gears. The method includes the following steps:

[0033] 1) Connect the bevel gear I1 to the rotating shaft 8 through the flat key 4 and mesh with the bevel gear II2, and bring the bevel gear I1 and the bevel gear II2 close to each other so that the meshing gap is zero, and at the same time make the rear end of the flat key 4 and the shaft The fit clearance of the keyway is adjusted to zero;

[0034] 2) Connect the bevel gear I1 and the flat key 4 through the top screw 5;

[0035] 3) Take out the flat key 4, and remove the set thickness on the semi-cylindrical surface at the rear end of the flat key 4;

[0036] 4) Reassemble...

Abstract

The invention belongs to the technical field of gear engaging gap adjusting, and specifically provides a method for adjusting an engaging gap of bevel gears. The method comprises the steps of 1) connecting the bevel gear I and a rotating shaft through a flat key; enabling the bevel gear I to engage with a bevel gear II; arranging the bevel gear I to be close to the bevel gear II until zero engaging gap is realized; and adjusting the fitting gap between the rear end of the flat key and a shaft key groove to be zero; 2) connecting the bevel gear I and the flat key through a jackscrew; 3) removing set thickness of a semi-cylindrical surface of the rear end of the flat key; and 4) re-assembling the flat key, the bevel gear I and the rotating shaft, thus obtaining accurate engaging gap betweenthe bevel gear I and the bevel gear II. With the adoption of the method, the engaging gaps of the bevel gears can be accurately adjusted without mounting reference.

Description

technical field [0001] The invention belongs to the technical field of adjusting the meshing clearance of gears, in particular to a method for adjusting the meshing clearance of bevel gears. Background technique [0002] The gear meshing clearance plays an extremely important role in the movement accuracy, contact accuracy and working stability in mechanical transmission. Such as figure 1 Shown in the existing equipment, the installation structure of the bevel gear. The specific structure is that the two bevel gears are respectively installed in the two sets of mechanisms, and the two sets of mechanisms have no positioning reference that can adjust the meshing clearance of the pair of bevel gears. Among them, the horizontal bevel gear I100 is fastened on the shaft by screws, and there is a gap h between it and the base surface. The structure of the horizontal bevel gear I100 is as follows: Figure 2-3 shown. It is not difficult to see that the existing design structure i...
