Problems solved by technology
The reason is that the traditional outdoor elevator adopts the structural type of wire rope drum drive or rack and pinion drive. The wire rope drum drive has defects such as large lateral force on the guide rail and great influence by natural environmental factors; With a single-pinion output gearbox, due to the limitation of processing conditions, the meshing rack must be manufactured in sections, and the cumulative tolerance of the entire rack during installation is relatively large, resulting in a sudden change in speed when the gearbox runs to the joint between the racks and Cannot be fully engaged, resulting in greater vibration and noise

Embodiment Construction
[0015] The present invention adopts the power double shunt form in the gear box of the outdoor elevator, and uses one motor shaft to drive two identical output gears at the same time. When fully meshed, the meshing between the output gear and the rack is adjusted through the double shunt load sharing mechanism, so that the gear box is evenly loaded.

The elevator 1000 has a rack and pinion lifting mechanism 100 , a motor 200 , an electric control box 300 and an elevator car 400 . The electric control box 300 contains electrical components for controlling the operation of the elevator. The motor 200 outputs power through its motor shaft 201 and transmits it to the rack-and-pinion lifting mechanism 100 , and the rack-and-pinion lifting mechanism 100 drives the elevator c...

The invention relates to an elevator capable of reducing vibration and noise, comprising an elevator car , a motor and a gear rack lifting mechanism, wherein the motor outputs power by a motor shaft; and the gear rack lifting mechanism comprises a power dividing component, a first output gear, a second output gear and lifting racks. The power dividing component is connected with the motor shaft in a transmission manner and is at least provided with a first dividing gear and a second dividing gear which are arranged at a same transmission shaft; and the first output gear and the second output shaft are respectively connected with the first dividing gear and the second dividing gear in a transmission manner by a transmission mechanism. By changing a meshing mode of the gears and the racks of the gear rack lifting mechanism, the elevator overcomes the incomplete meshing brought by the accumulated tolerance when the racks are installed, thus guaranteeing that the elevator maintains smooth running and low-noise working in the lifting and falling process.
Description
technical field [0001] The invention relates to an elevator, in particular to an elevator with reduced vibration and noise. Background technique [0002] Outdoor elevators are the basic supporting facilities for every large and medium-sized outdoor project. As engineering operations become more and more modern, the requirements for outdoor elevators are becoming increasingly stringent. There is an urgent need for safer, more comfortable and environmentally friendly elevators to ensure the overall quality of the project. [0003] Some outdoor elevators currently on the market produce a noise of 90 to 95 decibels during a working stroke within 100 meters, and often vibrate when crawling. The reason is that the traditional outdoor elevator adopts the structural type of wire rope drum drive or rack and pinion drive. The wire rope drum drive has defects such as large lateral force on the guide rail and great influence by natural environmental factors; With a single-pinion output...
