Embodiment 1

[0019] The first kind of embodiment of the present invention a kind of processing method of standard spherical involute spur bevel gear, it comprises the following several steps:

[0020] (1) gear blank processing, utilize the forging process to make the tooth blank of gear;

[0021] (II) Tooth profile processing, on the straight bevel gear planer, utilize the planer cutter to process the required spherical involute straight bevel gear according to the principle of "production shape gear";

[0022] as attached figure 1 As shown, the tooth surface of the traditionally processed straight bevel gear is inclined, while the theoretical tooth surface of the spherical involute spur bevel gear is processed is a curved surface rather than a plane, and its tooth surface equation is:

[0023] P r → = R sin α ...

Abstract

The invention discloses a method for machining a standard spherical involute spur bevel gear. The method comprises the following steps of: (I) teeth blank machining: manufacturing a teeth blank of a gear by using a forging process; (II) tooth form machining: machining the standard spherical involute spur bevel gear as required by using a gear shaper cutter on a spur bevel gear shaper according to a principle of generating a gear of a gear; (III) thermal treatment of the gear: performing thermal treatment on the gear subjected to initial machining; and (IV) finish machining of the gear: performing finish machining on the gear subjected to thermal treatment to obtain the gear meeting requirements. The gear machined by using the method for machining the standard spherical involute spur bevel gear, provided by the invention has the advantages of high precision in tooth form and tooth profile, transmission stability and high comprehensive performance.

Description

technical field [0001] The invention relates to a processing method of a transmission part, in particular to a processing method of a standard spherical involute straight bevel gear. Background technique [0002] Spherical involute straight bevel gear is one of the most basic parts used to transmit parallel axis motion and power in the mechanical field, and is widely used in various mechanical equipment such as mining, metallurgy, construction and transportation. At present, spherical involute straight bevel gears are usually processed on a straight bevel gear planer, using two standard planer cutters fixed on the tool holder to process the spherical surface with a special tool planer according to the principle of "production shape gear". Tooth profile of an involute spur bevel gear. During processing, the upper and lower tool holders of the straight bevel gear planer perform linear reciprocating cutting motions, and the entire tool holder is installed on the cradle, and sw...
