Embodiment Construction

[0011] As shown in the accompanying drawings, the reduction box gear for a single-phase capacitor running motor of the present invention includes a gear body 1, and the addendum circle of the gear body 1 and the meshing surfaces on both sides present a streamlined transition. The streamlined transition is formed by cutting off 0.01-0.015m (modulus) from the addendum circle along the meshing surfaces on both sides to the root direction of 0.4-0.5m (modulus) for edge trimming. How much of concrete trimming amount can be determined according to the size of the gear and the size of the noise generated, in the present embodiment, its trimming amount is to cut off 0.012m (modulus) between 0.4~0.5m (modulus). Since the edge is trimmed between the addendum circle of the gear body 1 and the meshing surfaces on both sides, the mechanical noise in the meshing process is greatly reduced.

Abstract

The present invention discloses a reduction box gear for a single-phase capacitance running motor, in particular to the reduction box gear for the single-phase capacitance running motor on a low voltage circuit breaker. The present invention consists of a gear main body, and has the structural characteristic that the addendum circle of the gear main body and meshing surfaces at the both sides are the streamline shape transition, wherein the streamline shape transition is formed through processing by thinning 0.01 m to 0.015 m thickness from the addendum circle to 0.4 m to 0.5 m of the dedendum direction along the meshing surfaces at the both sides. The reduction box gear for the single-phase capacitance running motor is adopted to greatly reduce the mechanical noise.

Description

technical field [0001] The invention relates to a gear. Specifically, it is a reduction box gear for a single-phase capacitor-operated motor on a low-voltage circuit breaker. Background technique [0002] As we all know, noise is composed of irregular and chaotic combination of sound waves with different frequency and sound intensity, and it has become one of the public hazards of polluting the environment. And mechanical noise is the main source of this public nuisance. Among them, the noise of dust produced by gear transmission is the main sound source of mechanical noise. Therefore, reducing gear noise is one of the main ways to reduce mechanical noise. [0003] At present, the reduction box gear equipped with the single-phase capacitor running motor for opening and closing of low-voltage circuit breakers has a steep transition between the addendum circle and the meshing surfaces on both sides, that is, between the addendum circle and the transition surface.
