Description

Elevator traction machine

Technical field

The utility model relates to the elevator technology field, specifically is the elevator traction machine of the gearless of the big diametral load of a kind of energy carrying.

Background technology

Elevator traction machine is a pith of elevator components, the towing machine that traditional elevator all is to use a motor and traction sheave, brake system etc. to form, used is supported and fixed on the motor base, traction sheave and brake system are that one hangs on outside the support, the integral installation mode is a cantilever design, be that bearing support and main frame are fixed on the frame, and link together by an axle.But the shortcoming of this towing machine is that the planeness requirement of frame is very high, and bearing support height of center and host center height will be consistent, and this three is extremely important, indispensable, otherwise can produce noise and vibration even damage bearing, towing machine is with regard to cisco unity malfunction like this, and also shorten service life.Therefore the anodontia towing machine that a kind of two ends band supports has appearred in the market, it as the disclosed patent No. on the State Intellectual Property Office website 200320128026.1 the synchronous anodontia towing machine of preceding supporting construction rare earth permanent magnet, it is exactly that the strong point of support has been located at the traction sheave both sides, promptly adopted double base, but also there is following shortcoming in the towing machine of this structure: only hold two bearings in two supportings respectively, cause the traction sheave between two supportings to be difficult for installing, and dismounting motor earlier when changing traction sheave, cause the dismounting trouble.

The utility model content

Technical problem to be solved in the utility model is that a kind of elevator traction machine of energy easy accessibility is provided.

For solving the problems of the technologies described above, a kind of elevator traction machine that the utility model provides, comprise bearing support, traction sheave, with drg bonded assembly brake wheel, electrical motor, described traction sheave is installed in the centre of bearing support, described brake wheel and electrical motor are installed in the both sides of bearing support respectively, described bearing support is by four crossbeams and the integral body that transverse slat constitutes, and a side of its dress motor has the hole, and the diameter in described hole is greater than the external diameter of traction sheave.

After adopting above structure,, and have the hole in a side of bearing support dress motor because bearing support is by four crossbeams and the integral body that transverse slat constitutes, and its diameter is greater than the external diameter of traction sheave, when the Assembly ﹠Disassembly traction sheave, can from the hole, pass through like this, very convenient.

As improvement, described bearing support is by Connection Block and motor bonded assembly, and described Connection Block and motor are located by connecting by male and female seam I, and described Connection Block and bearing support also are located by connecting by male and female seam II.Adopt Connection Block to connect bearing support and motor, make when changing parts and need not dismantle all parts, make maintenance more convenient.

Described bearing support can also be direct and electrical motor bonded assembly.

As further improvement, on the motor shaft of described motor coder is installed.After having adopted coder, can make the data of towing machine feed back to control center and handle, thereby realize automation.

Described brake wheel is the drum brake wheel, and described coder is installed in the axle head of motor side.When adopting the drum brake wheel, this structure can make installation more convenient.

Described brake wheel is the disc type brake wheel, and described coder is installed in the axle head of motor side, also can be installed in the axle head of brake wheel side.When adopting the disc type brake wheel, can be installed in different parts to coder as required, make installation and use more convenient.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.

By Fig. 1, the structural representation of the utility model elevator traction machine shown in Figure 2 as can be known, this elevator traction machine, comprise bearing support 9, traction sheave 4, with drg 1 bonded assembly brake wheel 2, motor 7, described traction sheave 4 is installed in the centre of bearing support 9, described brake wheel 2 and motor 7 are installed in the both sides of bearing support 9 respectively, described bearing support 9 is by four crossbeams 3 and the integral body that transverse slat 5 constitutes, four crossbeams 3 and a transverse slat 5 of being described bearing support 9 are casting all-in-one-pieces, can guarantee the height of center and the high conformability of host center of bearing support so better.One side of its dress motor 7 has macropore 10, and the diameter of described macropore 10 is greater than the external diameter of traction sheave 4.Described bearing support 9 is by Connection Block 6 and motor 7 bonded assemblys, and described Connection Block 6 is located by connecting by male and female seam I12 with motor 7, and described Connection Block 6 also is located by connecting by male and female seam II 11 with bearing support 9.Coder 8 is installed on the motor shaft of described motor 7.Described brake wheel 2 is the drum brake wheel, and described coder 8 is installed in the axle head of motor 7 sides.After adopting Connection Block 6, when dismounting traction sheave 4, only need Connection Block 6 unloaded from supporting base 9 and get final product, need not motor 7 is unloaded from Connection Block 6, therefore dismounting easily, fast.

By the utility model elevator traction machine scheme drawing shown in Figure 3 as can be known, the motor 7 of this elevator traction machine can not need Connection Block 6 with being connected also of supporting base 9, and at this moment, motor 7 directly is fixedly connected on the supporting base 6.Motor 7 also will be dismantled during dismounting.

By the schematic perspective view of the utility model elevator traction machine tep reel formula brake wheel shown in Figure 4 as can be known, when brake wheel 2 is the brake wheel of disc type, two of 1 needs of required drg, described coder 8 is installed in the axle head of motor 7 sides, also can be installed in the axle head of brake wheel 2 sides, coder 8 is positioned at brake wheel 2 sides among the figure, does not show.

The utility model elevator traction machine is not limited to above-described structure, and when Connection Block 6 not being set, brake wheel 2 can be a disc type, also can be drum-type.These variations all fall within the utility model protection domain.
