Worm and Gear Of Motor Reducer For Construction Hoist

1. Introduction

①. This worm and gear of motor reducer is mainly used in the motor reducer for the construction hoist or passenger hoist.

②. Optimization design of main parameters such as center distance and ratio. High interchangeability for main components.

③. Gears are made of high-class alloy steel, with carburization and quenching treatment. Gear surface hardness of HRC54 – 58.

④. Compact size, light weight, high precision, big carrying capacity, high efficiency, long service life, high reliability, stable transmission, low noise.

⑤. Normally oil sump lubrication is used, with cooling naturally.

2. Features

①. The worm and gear of motor reducer have a high precision procession. They have the quality test through the detector and have a long service life.

②. Good bearing capacity and high transmission efficiency.
