Reducer is a relatively sophisticated machinery, the use of its purpose is to reduce rotation speed, increase torque. Its sort is various, different types, different kinds have differentuses.There are many types of reducer, according to the transmission type can be divided into gear reducer, worm gear reducer and planetary gear reducer.According to the different can be divided into single-stage and multi-stage transmission series reducer.According to the gear shape can be divided into cylindrical gear reducer, cone gear reducer and the cone - cylinder gear reducer.According to the transmission can be divided into the expansion of decorate a form, shunt type and coaxial reducer.Scraping machine speed reducer is a special reducer for the coal industry production, with high reliability, large carrying capacity, the characteristics of safety, power is 7.5 kw to 525 kw, speed ratio range of 16-45. Scraping machine speed reducer is tapered cylindrical structure of planetary gear reducer, the first level of arc tooth taper gear, intermediate grade for cylindrical gear transmission, the output level for the planetary gear transmission, it is mainly used for mine belt conveyor transmission parts, can also be used for other mechanical industry.
