- Brief Description
ZD wholesale motor reducer is an external involute cylindrical gear reducer produced according to the national professional standard ZBJ19004. The gear reducer is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmaceutical and other fields.
ZD wholesale motor reducer structure than the traditional transmission is simple, smaller size, it neither manual transmission of many gear pairs, nor automatic transmission complex planetary gear set, it is mainly by the main, driven wheel and metal to achieve stepless change in speed ratio.
- Classification type description
- The ZD wholesale motor reduceris made of high strength and low carbon alloy steel through carburizing and quenching. The tooth surface hardness is up to hrc58-62.
- HighZD wholesale motor reducer rate: single stage greater than 96.5%, double stage greater than 93%, tertiary greater than 90%.
Smooth operation and low noise.
- Small size, light weight, long service life, high carrying capacity.
- Easy to disassemble and check, easy to install
This ZD wholesale motor reducer has the advantages of strong universality and interchangeability, simple maintenance, efficiency coefficient of 0.94, small starting resistance, flexible movement and so on. The structure of the machine is two - stage three - axis helical cylindrical horizontal segmentation full seal type. Lubricating oil is used in the inner part of the reducer, there are oil baffles on the driving shaft and intermediate shaft, the fulcrum of each shaft is used rolling bearing, the axial clearance can be adjusted by the internal adjusting ring, the upper part of the machine has an inspection cover, the lower part has oil standard pointer and oil plug for waste oil.
Gear and shaft are made of high quality carbon steel, and the conditioning treatment, multi-purpose senior casting steel ZD wholesale motor reducer manufacturing, and the normalizing treatment, body material is gray cast iron HT - 200 and after aging treatment, according to the magnitude 8 precision manufacturing hobbing helical gear tooth, Angle 8 ° 6 '34 ", both spouses gear teeth and 99 teeth.
- Usable Range
The application range of gear reducer ZD wholesale motor reducer is as follows:
- High-speed shaft rotation shall be no more than 1500 RPM.
- The circular speed of gear transmission shall not be more than 20 m/s.
3, working environment temperature for - 40-45 ℃, if lower than 0 ℃, before the start of lubricating oil should be preheated to more than 0 ℃, gear speed reducer can be used for positive and negative two directions.
The transmission parts and bearings of reducer need good lubrication in order to ZD wholesale motor reducer friction and wear. Improve efficiency, rust prevention, cooling and heat dissipation. Most of the transmission parts of reducer are lubricated by oil. The oil-immersed lubrication is used in the lubrication mode, and the pressure oil injection lubrication is used in the high-speed transmission. Sufficient lubricating oil should be provided in the box to ensure lubrication and heat dissipation in order to avoid the rotation of large gears.
When the sediment at the bottom of the oil pool is stirred up, the distance from the top circle of the big gear to the bottom of the oil pool should be greater than 30-50 mm. In order to ensure full lubrication of ZD wholesale motor reducer parts and avoid excessive loss of stirring oil, proper immersion depth should be provided for transmission parts.
