Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0023] like figure 1 and Image 6 As shown, the dry screw compressor includes a fuselage, a transmission shaft 1, a flange 2, a main transmission gear 3, a rear protective cover 4, a fan 5, an outer cover 6, a driven gear 7, a main synchronous gear 8, and a secondary synchronous gear 9. Male screw 10, female screw 11, seals and moving parts. The fuselage comprises an air intake cover 23, a cylinder block front cover 24, a cylinder block 25 and a rear cover 26 arranged in sequence from before, and the rear cover 26 and the cylinder block front cover 24 are respectively arranged at the two ends of the cylinder block 25 and fixedly connected by bolts. The male screw 10 and the female screw 11 are mutually supported and arranged in parallel between the rear cover 26 and the front cover 24 of the cylinder body, that is, in the cylinder body 25. T...

Abstract

Provided is a dry screw compressor. The dry screw compressor comprises a compressor body, a transmission shaft, a main drive gear, a driven gear, a main synchronous gear, a subsidiary synchronous gear, a positive screw and a negative screw, wherein the transmission shaft, the positive screw and the negative screw are arranged on the compressor body in parallel, and the transmission shaft is located below the positive screw and the negative screw; the transmission shaft is fixedly sleeved with the main drive gear, the driven gear and the main synchronous gear are fixedly arranged at the end of the positive screw in a sleeving mode, and the driven gear is engaged with the main drive gear; and the subsidiary synchronous gear is fixedly arranged at the end of the negative screw in a sleeving mode and engaged with the main synchronous gear. According to the dry screw compressor, the problem of loss of efficacy of bearings is solved, and the situation that the bearings have no lubrication under high temperature and high pressure is prevented; and in addition, a lubricating oil loop is arranged in a gearbox, the gears and the bearings can be well lubricated, and the service lives of sealing parts are prolonged.

Description

technical field [0001] The invention relates to a dry screw compressor. Background technique [0002] At present, domestic oil-free screw air compressors basically rely on imports, and they are not yet able to produce them. Some manufacturers advertise oil-free air compressors that are actually oil-free, and they have not achieved real oil-free air compressors. The main technical problems are as follows: : [0003] The screw of the oil-free screw air compressor works at high speed (10000rpm) and large flow. The screw will generate high temperature without oil cooling, the temperature between the screw and the chassis is high, and the thermal expansion is large, which can easily lead to screw seizure and bearing failure. , the lifespan decreases. The lead parameters of the screw cannot be solved well, the gap between the screws is not well controlled, and the life of the screw is short. The sealing problem cannot be solved well, because it is high temperature and high flow...
