Chain drive screening pulverizer

Abstract

The invention relates to a chain drive screening pulverizer, which comprises a cylinder, a feeding mechanism, a discharging mechanism, a hollow shaft, a hollow shaft supporting mechanism and a transmission mechanism, wherein the supporting mechanism comprises a static pressure main bearing and a high and low-pressure lubrication station, and the transmission mechanism comprises a motor, a speed reducer and a cranked link chain; the output end of the motor is connected with the input end of the speed reducer through a hydraulic coupling, and one end of the cranked link chain is connected with the output end of the speed reducer; the other end of the cranked link chain is connected with the cylinder, and the motor drives the cylinder to rotate through the cranked link chain. The chain drive screening pulverizer provided by the invention adopts chain drive, and the chain drive is meshed drive with an intermediate flexible part, and has the characteristics of belt drive and gear drive; the chain drive does not need a large initial pull force, so the pressure on a shaft is small; the chain drive can realize large-center-distance drive like the belt drive, and is much lighter than the gear drive.

Description

technical field [0001] The invention relates to the technical field of screening type grinding equipment, in particular to a chain-driven screening type grinding machine. Background technique [0002] In traditional crushing and grinding equipment, the commonly used mechanical transmission devices are belt transmission and gear transmission. Belt transmission is a flexible transmission with stable transmission, low noise, and can absorb vibration. When overloaded, the belt will slip on the pulley, thereby protecting other transmission parts from damage. The belt transmission allows a larger center distance. The structure is simple, the manufacture, installation and maintenance are more convenient, and the cost is low. However, due to the slip between the belt and the pulley, the transmission ratio cannot be kept strictly unchanged, the transmission efficiency of the belt drive is low, and the life of the belt is generally short. The gear transmission is stable, the transmis...

Problems solved by technology

Belt transmission is a flexible transmission with stable transmission, low noise, and can buffer and absorb vibration. When overloaded, the belt will slip on the pulley, thereby protecting other transmission parts from damage. The belt transmission allows a larger center distance. The structure is simple, the manufacture, installation and maintenance are more convenient, and the cost is low, but due to the slip between the belt and the pulley, the transmission ratio cannot be kept strictly unchanged, the transmission efficiency of the belt drive is low, and the life of the belt is generally short

The gear transmission is stable, the transmission ratio is accurate, the work is reliable, the efficiency is high, the service life is long, and the power, speed and size range used are large. However, special equipment is required to manufacture the gears. The manufacturing precision is high and the cost is high. When the precision is low, vibration and Noisy, not suitable for transmission with large distance
