Problems solved by technology
like figure 2 and Figure 4 As shown, the traditional method is to place a sheet-shaped adjustment pad between the bearing seat of the bevel gear and the supporting shell. This method needs to arrange fastening screws in the circumferential direction and requires a large layout space; the other method uses adjustment blocks. Axial adjustment, the adjustment block used in this method needs to be ground with a series of thickness adjustment blocks during trial assembly, and then adjusted according to the actual assembly situation, which is time-consuming and material-consuming, and the adjustment block needs to be re-ground when replacing the bevel gear

The invention relates to a compact axial adjustment mechanism for a spiral bevel gear. The spiral bevel gear includes: a bevel gear and a drive shaft of the bevel gear. The adjustment mechanism includes: The supporting shell, the base and the roller bearing are provided; an annular member composed of two half rings is arranged between the adjacent interface of the supporting shell and the base; the cross section of the annular member is boss-shaped, Both sides of the protruding block of the boss are respectively provided with adjusting pieces; the adjusting piece is an annular adjusting piece composed of two adjusting half-rings. The adjustment member provided by the present invention can conveniently and quickly adjust the axial direction of the bevel gear through the arrangement and combination of different adjustment member thicknesses, and realize a certain range of axial adjustment; at the same time, it avoids multiple times in the assembly process after the bevel gear is processed. Time-consuming and labor-intensive and cost-increased costs caused by measurement and multiple processing of adjustment parts.
Description
technical field [0001] The invention relates to an adjustment mechanism, in particular to a compact axial adjustment mechanism for a spiral bevel gear. Background technique [0002] Spiral bevel gears have the characteristics of stable transmission, low noise, high load capacity, easy adjustment of contact area, and less sensitivity to errors and deformations. They are widely used in intersecting shaft transmissions of medium and high-end transmission equipment. [0003] At present, the basic tooth profiles of domestic spiral bevel gears are slightly different according to different processing methods, which can be mainly divided into Greenson tooth system and Klingenberg tooth system. Such as image 3 As shown, there is a deviation between the actual installation distance of the spiral bevel gear and the theoretical installation distance, and there is also a deviation between the processing size of the bevel gear support structure and the theoretical value. If there is a l...
