Abstract
The utility model discloses a motor shaft for an industrial ventilation system. The motor shaft comprises a locking end, a fan blade mounting shaft, a balancing shaft and a motor connecting shaft, wherein the locking end, the fan blade mounting shaft, the balancing shaft and the motor connecting shaft are sequentially connected; the locking end is provided with a thread; the length of the fan blade mounting shaft is more than one meter; the weight of the balancing shaft is more than 0.8 kg; a graphite ring is arranged on the motor connecting shaft. According to the motor shaft for the industrial ventilation system, a plurality of fan blades can be mounted on the motor shaft, shake of the whole shaft can be reduced after the plurality of fan blades are mounted, and thereby the shaft body is kept in balance, and dust is prevented from entering into the bearing and the motor.
Description
Technical field
The utility model relates to industrial air exchange system field, specifically relates to a kind of industrial air exchange system motor shaft.
Background technique
Existing industrial air exchange system motor shaft is very short, and single flabellum generally can only be installed, and just needs so many transfers axle and multiple drive mechanism in the time that needs are installed multiple flabellum.Some inevitable wastings of resources are so just caused.
In addition in industrial air exchange system, there are many floating debriss, easily motor and bearing etc. are produced and stopped up.
