Technical Field

The invention relates to the field of gear machining detection, in particular to an online detection gauge for the tooth thickness of a bevel gear forging.

Background

The straight bevel gear is commonly called a bevel gear, and the shape of the straight bevel gear is conical or umbrella-shaped. Bevel gears are used to transmit motion and power between two intersecting axes, and in general machines, the angle of intersection between the axes of bevel gears is equal to 90 ° (but may not be equal to 90 °). Like cylindrical gears, bevel gears have reference cones, addendum cones, dedendum cones, and base cones. The cone has a large end and a small end, and the circles corresponding to the large end are respectively called a reference circle (the radius of the reference circle is r), an addendum circle, a dedendum circle and a base circle. The motion of a pair of bevel gears is equivalent to that of a pair of pitch cones which roll only. The bevel gear is one of indispensable important component parts in the automobile differential mechanism, and if a problem occurs, the assembly of the automobile is directly influenced, even the assembly line is stopped, and irreparable economic loss is caused. At present, the bevel gear is produced in batch by a precision forging forming process in the industry. In the process of mass production, if the finish forging die deforms on the tooth shape, the final meshing area and the size of the side gap of the product are directly affected, and therefore products cannot be interchanged among batches.

In the prior art, a three-coordinate detection center is generally adopted to detect the tooth profile, but the method is long in period and high in cost and is not suitable for large-scale detection in the production process, the existing bevel gear tooth thickness online detection tool needs to fix a bevel gear by using a mandrel when in use and then can detect the tooth thickness, different main gears need to be fixed by using mandrels with different sizes, the use cost is increased, the practicability of the detection tool is greatly reduced, the existing bevel gear tooth thickness online detection tool needs to frequently lift a dial indicator and rotate the bevel gear when in use, and the work burden of operators is increased, so that a new bevel gear forging tooth thickness online detection tool is developed.
