Abstract

The invention discloses a high-precision hot die forging device for a sun gear for a planetary reducer. The high-precision hot die forging device for the sun gear comprises a forging assembly, a synchronous assembly, a tooth expanding assembly and a pressing assembly, the synchronous assembly is located in the forging assembly and fixedly connected with the forging assembly, the tooth expanding assembly makes contact with the forging assembly, and the pressing assembly is fixedly connected with the forging assembly. The synchronous assembly is located above the tooth expanding assembly. The forging assembly is used for forging a steel raw material, the synchronous assembly can ensure that the forging assembly moves while the tooth expanding assembly can move according to the movement of the forging assembly, the tooth expanding assembly is used for expanding an inner ring and an outer ring of a gear to a certain degree, and the sun gear needs to be meshed with several gears at the same time, so that the precision of the sun gear is very important. The pressing assembly can compress an expanded circular ring, so that the inner ring precision and the outer ring precision of the circular ring are suitable for further machining of the gear and meet the requirements, and the high-precision hot die forging device for the sun gear for the planetary reducer has good practicability.

Description

technical field [0001] The invention relates to the field of gear processing, in particular to a high-precision hot die forging device for a sun gear used in a planetary reducer. Background technique [0002] Gears are devices that mesh with each other to transmit force and motion. Gears and the products produced by gears are the foundation of modern industry. Most complete sets of devices operate in sets. Gears are parts that are needed for almost every precision instrument. A small piece of A small mechanical watch integrates many gears inside, and the gears are also used in vehicles, large ships and other machinery, and play an irreplaceable role in our lives. [0003] The sun gear is the middle gear in the planetary gear system. This gear is driven by external kinetic energy and further drives other gears to rotate, so it requires very high precision. The current production process cannot guarantee the accuracy of the sun gear, and the forging process is very cumbersome....
