Abstract

The invention discloses a new-type electric oil-free air compressor, which comprises a mounting base, wherein a servo motor is fixed at the upper end of the mounting base and provided with motor spindles; eccentric wheels are fixed on the motor spindles; driving cylinders are fixed on the eccentric wheels and rotationally connected with piston connecting rods; the piston connecting rods are rotationally connected with rotating shafts, which are rotationally connected with pistons; the upper ends of the pistons are clamped by sealing rings; the outer surfaces of the pistons are connected with piston cylinder blocks in a sliding manner; wear-resistant layers are arranged on the inner cylindrical surfaces of the piston cylinder blocks; the lower ends of the piston cylinder blocks are communicated with eccentric wheel boxes, which are fixed on the servo motor; piston cylinder covers are fixed at the upper ends of the piston cylinder blocks; one sides of the piston cylinder covers are communicated with air outlet pipes; and the middles of one sides of the eccentric wheel boxes are communicated with air inlet pipes. Through the above structure, the oil-free lubrication of the air compressor is achieved, so that the energy consumption is low and the environmental pollution is less.

Description

technical field

[0001] The invention belongs to the technical field of mechanical manufacturing, and in particular relates to a novel electric oil-free air compressor. Background technique

[0002] With the gradual improvement of people's awareness of the environment and environmental protection, urban residents in developing my country gradually realize that a good environment is the basic guarantee for work and physical and mental health. The state advocates and encourages urban residents to choose pure electric new energy buses for travel. In order to reduce bus operation noise and energy consumption and improve operation reliability, clean compressed air is used as energy source for bus braking, which makes oil-free air compressors emerge as the times require. In order to alleviate the increasingly congested urban traffic, buses tend to be large in size and high in power. In order to ensure the transportation capacity of buses and reduce energy consumption, the weight o...
