Description

Escalator motor
Technical field
The present invention relates to electric motors, particularly a kind of escalator motor.
Background technology
For the drive motor of escalator, owing to relating to the brake request of escalator, brake mechanism and motor combination mode have three kinds at present.The first is split type upper brake structure, and brake structure is arranged on the outside non-main shaft of motor and stretches end, the second is split type lower brake structure, and the main shaft that brake structure is arranged on motor outside is stretched a side, the third is the lower brake structure of integral type, and the main shaft that brake mechanism is arranged on motor interior is stretched a side, its concrete structure is shown in Fig. 1, the rear end cap 1 ' that has air outlet window is fixedly connected with by screw with support 5 ', rotor 3 ' fit is arranged on motor shaft, impeller 2 ' adopts on key connecting mode mounted motor axle and is placed in a side of rotor 3 ', the brake disc 6 ' that has a ventilation hole adopts key connecting mode to be arranged on motor shaft and is placed in the opposite side of rotor 3 ', the structure of brake disc 6 ' is shown in Fig. 2, brake block 7 ' is arranged on the outside of brake disc 6 ' and matches in brake disc 6 ', the front end housing 8 ' that has air-inlet window adopts screw to be connected with support 5 ', there is winding stator core 4 ' to be fitted on the rib of support 5 '.In prior art, have between the outer wall of winding stator core 4 ' and the inwall of support 5 ' and have space, the air outlet window of the air-inlet window of this space and front end housing 8 ', the ventilation hole of brake disc 6 ', rear end cap 1 ' forms a heat dissipation wind channel, sees Fig. 1.In the time of motor operation, impeller 2 ' and rotor 3 ' synchronous rotary, cooling-air is via heat dissipation wind channel, and the heat that motor interior is produced is extracted motor out by impeller 2 ', and the fan blade on the cast-aluminum rotor of rotor 3 ' is for auxiliary heat dissipation.Noise and vibration while operation in order to reduce motor, impeller 2 ', rotor 3 ', braked wheel 6 ', before motor assembling, all need independent manufacture, processing dynamic balance checking.
In addition, in prior art in the time that motor assembles, impeller 2 ' and brake disc 6 ' are arranged on respectively the cast-aluminum rotor both sides unshakable in one's determination of rotor 3 ', and both outside diameters are all greater than the interior circular diameter that has winding stator core 4 ', therefore the one in impeller 2 ' or brake disc 6 ' must be arranged on rotor 3 ' in advance, be placed in again behind winding stator core 4 ' inside, then adopted special tooling that remaining brake disc 6 ' or impeller 2 ' are arranged on rotor 3 '.After motor assembling, if need to split out rotor 3 ' because of fault or other reason time, also will first use special tooling that the one in impeller 2 ' or brake disc 6 ' is split out.Again, because of the blade reason on impeller 2 ', increased the axial dimension of motor.Therefore, under integral type of the prior art brake structure motor have that processing parts is many, manufacturing cost is higher, Product Assembly and the shortcoming such as dismounting operation is loaded down with trivial details, product size is larger.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of reduction manufacturing cost, Product Assembly and dismounting operation simple, the escalator motor of simplified manufacturing process.
The present invention addresses the above problem adopted technical scheme: a kind of escalator motor, comprise the front end housing that has air-inlet window, have ventilation hole brake disc, support, stator core, rotor, wind deflector, offer rear end cap and the motor shaft of air outlet window, rear end cap is fixedly connected with support, rotor fit is arranged on motor shaft, impeller is arranged on motor shaft and is placed in a side of rotor, brake disc is arranged on motor shaft and is placed in the opposite side of rotor, brake block is arranged on the outside of brake disc, front end housing is fixedly connected with support, unit stator iron core pressing is on the rib of support, in described brake disc, edge is circumferentially with multiple blades, the through hole that described wind deflector is provided with through middle part is installed on described motor shaft, and the free end of described wind deflector is fixed on rear end cap.
Compared with prior art, the invention has the advantages that: this escalator motor is cancelled the impeller of being made up of cast aluminium of prior art, the inner blade that increases of brake disc, installs a wind deflector on rear end cap.In motor when operation,, brake disc and rotor synchronous rotation, produce axial flow when blade rotary on brake disc, along heat dissipation wind channel, the heat of motor generation taken away effectively.This escalator motor simplified manufacturing process, manufacturing cost reduces, and motor axial dimension shortens, and has simplified the assembly technology of motor, has cancelled the required impeller of original-pack timing special tooling is installed, and reduces labour intensity.And after motor assembling, if need to split out rotor because of fault or other reason time, only need to twist bolt rear end cap is pulled down, wind deflector can take off in the lump, and dismounting is all very convenient.
