Key groove machining device for helical gear

Abstract

The invention relates to the field of helical gear machining, in particular to a key groove machining device for a helical gear. The machining device comprises a helical gear placing mechanism, a keygroove drawing positioning mechanism, an auxiliary positioning mechanism, a tooth groove bar inserting mechanism and a bar inserting driving mechanism. The helical gear placing mechanism is used for placing a helical gear to be machined, the top of the helical gear placing mechanism is provided with the key groove drawing positioning mechanism, the side part of the helical gear placing mechanism is provided with the auxiliary positioning mechanism, the top of the key groove drawing positioning mechanism is provided with the tooth groove bar inserting mechanism, the bar inserting driving mechanism is in driving connection with the tooth groove bar inserting mechanism, and the bar inserting driving mechanism drives the tooth groove bar inserting mechanism to perform bar inserting work. The machining process of a key groove is improved, the requirement that the center of the gear groove of the end face of a herringbone gear, the center of the key groove of an inner hole and the center ofa hole are located in the same line is met, and the symmetry degree precision of key groove machining is improved.

Description

technical field [0001] The invention relates to the field of helical gear processing, in particular to a processing equipment for helical gear pair key grooves. Background technique [0002] It is a common part often used in mechanical transmission. The gear is made of high-quality high-strength alloy steel, and the surface is carburized and hardened. It has a strong bearing capacity and is durable. In practical applications, helical gears are widely used in high-speed and heavy-duty occasions due to their stable transmission, low impact, vibration and noise. Helical gears are not exactly helical gears. It should be said that helical gears are the meshing mode of two helical gears, which are distinguished by the different directions in which they transmit force in space. Ordinary spur gears are meshed at the same time along the tooth width, resulting in impact vibration noise and unstable transmission. The transmission of helical spur gears is better than that of straight ...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide a processing equipment for helical gears to key grooves. This technical solution solves the problem that the angle of the helical gear adjustment process is not high. The processing equipment improves the processing process of key grooves to ensure the The center of the tooth groove on the end face, the center of the keyway of the inner hole and the center of the hole are required to be on the same straight line, which improves the symmetry accuracy of the keyway processing
