1、 Gear reducer is an external involute helical gear reducer produced according to the national professional standard zbj19004. Gear reducer is widely used in East China and is used in the slewing mechanism of tower crane machinery. It is widely used in metallurgy, mining, lifting, transportation, cement, construction, chemical industry, textile, printing and dyeing, pharmaceutical and other fields.
2、 As a necessary component of the transmission products such as screw lifter, the stability of hard tooth reducer plays an important role in the whole transmission system. However, if the hardness of the hard gear reducer fails to meet the requirements, or the service cycle is too long, or the load is overloaded, the wear of the hard gear will be accelerated, which will affect the normal operation of the transmission system.
（1） : main performance of failure after long-time use: vibration and noise increase during use. The main reason for this phenomenon is: the internal parts of the chassis are worn too much or damaged.
（2） : possible damaged parts: worn gear tooth surface, broken gear tooth, worn gear shaft hole or keyway; The screw hole at the bearing hole is easy to fail due to wear; Shaft surface and keyway are easy to wear due to long service time.
（3） : repair method: this repair method does not mean that all repair offices have the technical strength to repair according to this method, but for large-scale equipment, if the repair point can be found to repair the parts, it will greatly save the overall cost of the enterprise.
01: if it is due to the wear of the keyway of the shaft hole on the shaft surface of the hardened gear reducer, the original accuracy of the parts can be restored by electroplating.
02: if the gear teeth of the hardened gear reducer are broken, it is necessary to re process new parts. In order to ensure the service life of the hard tooth surface reducer, friends must choose a good type when purchasing the hard tooth surface reducer, ensure the safety factor of the hard tooth surface reducer, and strictly follow the instructions to give full play to the maximum efficiency of the hard tooth surface reducer
3、 Transmission advantages of hard gear reducer
In order to adapt to the fierce market competition and better serve the domestic metal products industry, the design of the transmission system of the wire drawing machine is also changing to the transmission form of the hard tooth surface gear. The specific performance is that at present, the market has adopted more combination of the strong narrow V-belt and the special hard tooth surface reducer of the wire drawing machine, and the standard reducer adapted to the overall structure of the wire drawing machine is adopted, And the reducer is effectively combined with the installation box, spindle, drum and so on to form a set of wire drawing machine transmission system with hard tooth surface gear as the main transmission form.
4、 Compared with the double enveloping worm gear pair, the standard hardened gear reducer has the following advantages
1. High transmission efficiency and strong bearing capacity;
2. The ratio is flexible and the combination is convenient;
3. Easy to install;
4. The cost is reasonable;
5. Modular design can be realized;
6. Trend, etc.
