Abstract
The utility model discloses a central transmission device for a backward rotary air preheater, which comprises a shell body, a transmission axle, a gear, a bevel gear, a bearing, an output axle and a rotor. The bevel gear and the gear are sheathed on the transmission axle. The output axle and the transmission axle are arranged on the shell body by the bearing. The rotor is arranged on the output axle and is positioned under the shell body. The bevel gear is simultaneously engaged with two or three bevel axles. A dry well type assembling sealing is arranged between the shell body of the output axle and the gear. The utility model has simple structure, stable operation, long service life, low operating cost, no abrasion and no oil leakage. The utility model is the ideal central transmission device for the backward rotary air preheater.
Description
The utility model relates to a kind of transmission device, particularly a kind of rotary regenerative air preheater central transmission.
Existing rotary regenerative air preheater generally adopts the transmission of pin tooth, owing to the rotor of rotary regenerative air preheater weighs greatly, makes the rotor inequality of being heated, the shroud circular runout is serious, and the pin tooth is exposed in many dirt hot environment, and working life is short, reliability is low, and pin tooth transmission cost height.
The purpose of this utility model just is to overcome deficiency of the prior art, provides a kind of simple in structure, operate steadily, and long service life, operating cost is low, does not does not wear and tear, oil tight rotary regenerative air preheater central transmission.The purpose of this utility model is to realize like this, it comprises: housing, transmission shaft, gear, bevel gear, bearing, output shaft, rotor, bevel gear, gear are contained on the transmission shaft, output shaft, transmission shaft by Bearing Installation on housing, rotor is contained on the output shaft and is positioned at the below of housing, bevel gear is meshed with three conical tooth shafts simultaneously, is provided with dry-well formula combination seal between output shaft housing and the gear.
Compared to existing technology, the utlity model has simple in structurely, operate steadily, long service life, operating cost is low, advantage such as do not wear and tear, oil-proof, and increased a cover or two cover drive units, improved reliability of operation.
Accompanying drawing and drawing explanation
Accompanying drawing is the utility model structural representation
Below in conjunction with drawings and Examples in detail the utility model is described in detail, it comprises: housing 2, transmission shaft 17,5,7,8, gear 18,16,4,6,15,9,14,11, bevel gear 3, output shaft 10, rotor 13, bevel gear 3, gear 18,16,4,6,15,9,14 are contained in transmission shaft 17,5,7,8, on, output shaft 10, transmission shaft 17,5,7,8, by Bearing Installation on housing 2, rotor 13 is contained on the output shaft 10 and is positioned at the below of housing 2, bevel gear 3 is meshed with three conical tooth shafts 1 simultaneously, is provided with dry-well formula combination seal 12 between the housing 2 of output shaft 10 and the gear 11.Working principle of the present utility model is, drive unit drives conical tooth shaft 1 and rotates, conical tooth shaft 1 drives bevel gear 3 driven gears 18,16,4,6,15,9,14,11 rotate, output shaft 10 drives rotor 13 and rotates the goal of the invention that realizes rotary regenerative air preheater work under the drive of gear 11, in the housing 2 lubricant oil is housed, each gear is lubricated, and under the effect of dry-well formula combination seal 12, make oil be difficult to bleed on the rotary regenerative air preheater, the utility model is simple in structure, operates steadily, long service life, operating cost is low, does not does not wear and tear, oil-proof, be a kind of desirable rotary regenerative air preheater central transmission.
