Product Feature
The gear reducer is a combination of a geared motor and a large reducer. No need for couplings and adapters, compact structure. The load is distributed on the planetary gears, so the carrying capacity is higher than that of general helical gear reducers. The gearbox gear of the car model meets the needs of high torque output in a small space.
Car model gearbox gears are widely used in large mines, steel, chemical industry, ports, environmental protection and other fields. Combining with K and R series can get bigger speed ratio.
1. Reliable industrial gear transmission components;
2. Combination of reliable structure and multiple inputs to meet special requirements;
3. It has high power transmission capacity and compact structure, and the gear structure is determined according to the principle of module design;
4. Easy to use and maintain, configure and select materials according to technical and engineering conditions;
5. The torque range is from 36,0000Nm to 1,200,000Nm.

When selecting a reducer for a car model reducer gearbox, it should be based on the selection conditions of the working machine, technical parameters, performance of the power machine, economy and other factors, and compare the outer dimensions, transmission efficiency, carrying capacity, quality, price, etc. of different types and varieties of reducers. , choose the most suitable reducer.
The load state of the working machine connected with the reducer is relatively complicated, and has a great influence on the reducer. It is an important factor in the selection and calculation of the reducer. The load state of the reducer is the load state of the working machine (driven machine). Usually divided into three categories: ①—uniform load, ②—medium impact load, ③—strong impact load.
Precautions
Causes of Gear Leakage in the Gearbox of a Car Model
1. The pressure in the fuel tank rises
In a closed reducer, each pair of gears meshes with each other and generates heat due to friction. According to Boyle-Mariotte's law, as the running time increases, the temperature inside the reducer case increases gradually, while the volume inside the reducer case Therefore, the pressure in the box increases accordingly, and the lubricating oil in the box is splashed and sprinkled on the inner wall of the reduction box. Due to the relatively strong permeability of oil, under the pressure in the tank, where the seal is not tight, the oil will seep from there.
2. Unreasonable structural design of the reducer causes oil leakage
For example, the reducer designed for car model reducer gear penetration does not have a ventilation cover, and the reducer cannot achieve pressure equalization, causing the pressure in the box to become higher and higher, and oil leakage occurs.
3. Excessive refueling
During the operation of the reducer, the oil pool is strongly stirred, and the lubricating oil splashes everywhere in the machine. If the amount of refueling is too much, a large amount of lubricating oil will accumulate on the shaft seal, joint surface, etc., resulting in leakage.
4. Improper maintenance process
During equipment maintenance, due to incomplete removal of dirt on the joint surface, improper selection of sealant, reverse installation of seals, and failure to replace seals in time, oil leakage will also occur.
