Planetary drive reducer for tube mill and tube mill equipment

Abstract

The invention discloses a planetary transmission reducer for a tube mill. The planetary transmission reducer comprises a rotating box and a fixed box, wherein a central shaft is arranged inside the fixed box; planetary transmission parts are arranged inside the rotating box; sun gears in the planetary transmission parts input force and rotate to drive inner gear rings to rotate and output force; and the rotating box is connected with the tube mill. Through the application of the reducer, planetary gear transmission is utilized, so that compared with a conventional parallel shaft reducer, the planetary transmission reducer has the advantages that the transmission ratio is increased, the transmission efficiency is improved, under the same output requirement, the sizes of the planetary transmission reducer and a matched motor are smaller, and the weights are lighter; a planet carrier relative mounting base is fixedly arranged, and after the sun gears input force, the planetary transmission parts transmit the force to drive the last stage inner gear ring fixedly connected with the rotating box to rotate; and the structure has flexible transmission property, the conventional eccentric load phenomenon can be effectively overcome, the impact vibration is reduced, the output is more stable, the service life is prolonged, the structure is simple, the manufacturing and transportation are convenient, the cost is low, and the popularization is facilitated.

Description

technical field [0001] The invention relates to a speed reducer, in particular to a planetary transmission speed reducer for a tube mill and tube mill equipment. Background technique [0002] Tube mill is an important fine grinding equipment in modern industry, widely used in building materials, metallurgy, mineral processing, electric power and chemical industries to grind cement and other materials, such as figure 1 Shown is the connection schematic diagram of the existing tube mill 01 and reducer 03, wherein the tube mill 01 is connected to the diaphragm coupling 02, the diaphragm coupling 02 is connected to the reducer 03, and the reducer 03 is connected to the motor 04, wherein the reducer 03 used is a parallel shaft reducer, which adopts parallel shaft transmission, that is, the input shaft of the reducer 03 is connected to the motor 04, and the input shaft in the reducer 03 is connected to the first-stage reduction gear and the first-stage reduction gear located at th...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the increase in volume and weight of the tube mill existing in the prior art. In the industry, the size of the matching reducer is simply enlarged according to the original structure, and the parallel shaft reducer is still used. Due to the tube mill and The size and weight of the reducer increase, especially the weight of the reducer reaches at least 60T. The volume and weight of the supporting motor are larger than before, and the output power requirements are higher. The manufacturing, transportation, structural installation, and site requirements of the reducer and motor The higher the requirements are, it is not conducive to energy saving, emission reduction, and cost reduction. At the same time, there are the above-mentioned deficiencies that the uneven load phenomenon affects the service life. A planetary transmission reducer for a tube mill and a tube mill equipment are provided. The planetary transmission reducer is relatively The existing parallel shaft reducer increases the transmission ratio and improves the transmission efficiency. Under the same output requirements, the planetary transmission reducer and the matching motor are smaller in size and lighter in weight, which can effectively overcome the existing partial load phenomenon and reduce the speed. The machine and the tube mill are directly connected, thus avoiding the severe impact and vibration caused by the different axes of the tube mill and the reducer center, making the output more stable and improving the service life
