Problems solved by technology

[0002] Nowadays, the demand for elevators in the market is increasing, and various types of elevators have been born, such as elevators driven by wire ropes and traction machines, and some people propose to use rack and pinion drive methods to realize the elevator car. Elevators with different drive modes also have their own advantages and disadvantages. For example, the elevator with rack and pinion drive mode is easy to install, saves space, and the gears and racks mesh with each other. However, the gears and racks cannot be completely Therefore, when the gear moves along the rack, when it transitions from one tooth structure to the next tooth structure, it will generate a lot of noise, which makes the elevator with this driving method unable to meet the standard requirements in terms of noise. Therefore, it is limited Application of gear and rack transmission mode in elevator industry

Abstract

The invention relates to a power mechanism of an elevator. The power mechanism comprises a rack installed on a shaft stand post, a gear engaged with the rack, a motor driving the gear to rotate, a mounting cross beam connected with the gear and a guide piece connected with the mounting cross beam, wherein the mounting cross beam is connected with an elevator car; a plurality of first tooth structures are obliquely arranged on the rack; and a plurality of second tooth structures are obliquely arranged on the gear. According to the power mechanism of the elevator, the first tooth structures areobliquely arranged on the rack, and the second tooth structures matched with the first tooth structures are arranged on the gear, so that the elevator car is driven to move up and down stably, the noise of the driving mode is eliminated, the noise of the elevator is in a standard range, and the market requirement is met.

Description

technical field [0001] The present invention relates to the technical field of elevator equipment, in particular to a power mechanism of an elevator. Background technique [0002] Nowadays, the demand for elevators in the market is increasing, and various types of elevators have been born, such as elevators driven by wire ropes and traction machines, and some people propose to use rack and pinion drive methods to realize the elevator car. Elevators with different drive modes also have their own advantages and disadvantages. For example, the elevator with rack and pinion drive mode is easy to install, saves space, and the gears and racks mesh with each other. However, the gears and racks cannot be completely Therefore, when the gear moves along the rack and transitions from one tooth structure to the next tooth structure, a large noise will be generated, causing the elevator with this driving method to fail to meet the standard requirements in terms of noise. Therefore, it is...
