Bulky motor for speed reducer, then the rolling bearing units removed at end cap are replaced, and it is difficult to dismantle in this way, and emergency repair time is very
It is long, cause flue gas emission annual average exceeded, influence the environment protection emission of entire company, loss is very big.
Utility model content
The purpose of this utility model seeks to overcome above-mentioned the shortcomings of the prior art, and providing one kind prevents bearing lubrication
The short circulating ash batcher drive mechanism of premature breakdown, raising service life, the emergency repair time of failing.
To achieve the above object, the utility model provides a kind of circulating ash batcher drive mechanism, including transmission shaft, described
Transmission shaft one end is fixedly connected with the output end of motor for speed reducer, and the other end passes through housing end plug and opposite with the housing end plug
Movement, the transmission shaft is also outer to be cased with sealing axle sleeve and rolling bearing units, the sealing axle sleeve both ends respectively with housing end plug and band
Seat bearing is fixedly connected, and the sealing axle sleeve lower end is provided with ash discharging hole.
Further, Hooks coupling universal coupling is also connected between the output shaft and transmission shaft of the decelerating motor.
Further, the sealing axle sleeve is additionally provided with boss, the boss and transmission on the inner wall of housing end plug side
Sealing ring is equipped between axis.
Further, the boss is fixedly connected with sealing gland, the sealing pressure on the end face of rolling bearing units side
Lid and transmission shaft clearance fit.
Preferably, cavity is formed between the sealing axle sleeve and transmission shaft, sealing axle sleeve inner wall lower end surface is spherical shape
Cambered surface, the ash discharging hole are located at the minimum point of spherical arc.
Preferably, the sealing axle sleeve further includes cushion block, and the cushion block both ends respectively can with sealing axle sleeve and rolling bearing units
Releasably affixed, the cushion block lower end is provided with ash discharging hole.
The beneficial effects of the utility model are: preventing bearing lubrication failure premature breakdown, improving service life, emergency repair time
It is short.It is provided with ash discharging hole in the lower end of sealing axle sleeve, between circulating ash is from sealing ring across sealing gland and transmission shaft
When gap reaches the cavity between sealing axle sleeve and transmission shaft, it can be directly discharged from ash discharging hole, prevent circulating ash from entering axis of usheing to seat
Holding leads to lubrication failure bearing damage；Furthermore it is connected between transmission shaft and geared motor output shaft using universal shaft coupling device, in this way
When being cleared up rolling bearing units and being repaired, Hooks coupling universal coupling only need to be dismantled, greatly shortens emergency repair time, reduced
Repairing workload ensure that the normal operation of equipment, and then guarantee that the amount of sulfur contenting in smoke annual average of system discharge is up to standard.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing, convenient for more clearly understanding that this is practical new
Type, but they do not constitute the utility model and limit.
As shown in figures 1-4, a kind of circulating ash batcher drive mechanism, including transmission shaft 1,1 one end of transmission shaft and the electricity that slows down
The output end of machine 10 is fixedly connected, and the other end passes through housing end plug 4 and relatively rotates with housing end plug 4, and transmission shaft 1 is also outer to be cased with
Sealing axle sleeve 3 and rolling bearing units 2,3 both ends of sealing axle sleeve are fixedly connected with housing end plug 4 and rolling bearing units respectively, sealing axle sleeve 3
