Description

Technical Field

[0001] This utility model relates to the field of grinding machine tool technology, and in particular to a spiral bevel gear external cylindrical grinding machine tool. Background Technology

[0002] Spiral bevel gears, also known as spiral conical gears, are commonly used for motion and power transmission between two intersecting shafts. The teeth of a bevel gear are distributed on the surface of a cone, with the tooth profile gradually decreasing from the large end to the small end.

[0003] Existing patents, such as Chinese Patent Publication No. CN211073017U, relate to the field of gear grinding technology and disclose a spiral bevel gear grinding machine. This machine includes a base plate, support plates fixedly installed on both sides of the top of the base plate, a top plate fixedly installed on the top of the support plates, a water tank fixedly installed on the right side of the base plate, a small base fixedly installed in the middle of the top of the base plate, a motor fixedly installed in the middle of the small base, and a rotating shaft fixedly installed on the top of the motor. This spiral bevel gear grinding machine integrates two grinding tools into one process by using multiple hydraulic rods. Previously, spiral bevel gear grinding required three cumbersome steps: top, side, and inner gear grinding. This new machine further reduces the grinding steps. The motor drives the spiral bevel gear to rotate and the grinding tools to perform the grinding, while the primary and secondary grinding tools remain stationary. Under the influence of the multiple hydraulic rods, only vertical adjustments are needed, greatly improving the machine's grinding efficiency.

[0004] Although the aforementioned patent only requires vertical position adjustment, greatly improving the grinding efficiency of the machine, the angle adjustment mechanism between the grinding wheel and the workpiece during the grinding of the outer diameter of the spiral bevel gear is relatively rudimentary. This makes it difficult to meet the diverse grinding angle requirements of complex spiral bevel gears. When machining some spiral bevel gears with special tooth profiles or large helix angles, it is easy to encounter difficulties in ensuring machining accuracy and an increased scrap rate. Therefore, a spiral bevel gear outer diameter grinding machine is needed to solve these problems. Utility Model Content
