Problems solved by technology

In order to adapt to the development trend of modern large-scale production, people continue to explore new tooth profiles. Under the existing technology, there will always be meshing impact at the tooth root and tooth top of the worm pair, which will greatly reduce the bearing capacity of the worm pair transmission and life, but also increases the transmission noise of the reducer and affects the transmission accuracy

Embodiment Construction

[0020] The utility model relates to an arc-shaped surface contact worm gear transmission power device for an escalator, and the worm is processed by a disc-shaped grinding wheel. figure 1 Schematic diagram of machining a worm for a disc wheel. First of all, according to the tooth surface equation of the disc grinding wheel and the actual processing parameters, combined with the design principle of the worm to determine the tooth surface equation of the worm, as shown in the figure, when processing the worm, when the worm is processed, the axis of the worm and the ring of the grinding wheel The axis of the surface (production surface) is installed with the helix angle of the worm indexing cylinder as the installation angle; the worm performs helical motion with certain helical characteristic parameters, and at the same time the grinding wheel rotates around its own axis to grind the worm tooth surface. Thus processing the worm. Then, according to the tooth surface equation of...

Abstract

The invention discloses an arc-shaped face contact worm wheel and worm transmission power device and belongs to the field of escalator speed reducers. According to arc-shaped face contact worm wheel and worm transmission, a multi-head arc-shaped cylindrical worm is adopted; a optimized mathematical model of a worm wheel and the worm is established based on an evolutionary fish swarm algorithm, andparameter optimization is conducted on a worm pair so that engagement performance of tooth faces can be obtained; tooth face curvature correction is conducted on the worm based on grinding machining,so that the tooth faces are engaged into arc-shaped face contact, and the instant contact line of the worm wheel and the worm is changed gradually and stably and distributed uniformly; and the instant contact line of the tooth faces is perpendicular to the relative movement direction of the tooth faces of the worm wheel and the worm. After optimization design is conducted on the worm wheel and the worm which are engaged with each other through the device, tooth face curvature correction is conducted on the worm, so that the tooth faces are engaged into arc-shaped face contact; mounting errorsare eliminated; and the normal direction of the tooth faces of the worm pair is perpendicular to the relative speed direction of the tooth faces of the worm wheel and the worm so that the worm wheeland the worm which are engaged with each other can have good lubricating performance.

Description

technical field [0001] The invention is applied to the field of escalator reducers, and in particular relates to an arc-shaped surface contact worm gear transmission power device for escalators. Background technique [0002] The reducer plays the role of matching speed and transmitting torque between the prime mover and the working machine or actuator. With the application and development of reducers in industry, the design and manufacturing level of reducers in my country is becoming more and more perfect. Affect the dynamic performance of worm gear transmission. In order to adapt to the development trend of modern large-scale production, people continue to explore new tooth profiles. Under the existing technology, there will always be meshing impact at the tooth root and tooth top of the worm pair, which will greatly reduce the bearing capacity of the worm pair transmission and It also increases the transmission noise of the reducer and affects the transmission accuracy. ...
