Abstract
The utility model relates to a belt transmission elevator tractor which comprises a motor, a brake disk, tooth-shaped belt wheels, a tooth-shaped synchronous belt and a traction wheel. The utility model is characterized in that a small tooth-shaped belt wheel is arranged on the motor, the torque of the small tooth-shaped belt wheel is transferred to a big tooth-shaped belt wheel by a tooth-shaped belt, and the big tooth-shaped belt wheel is coaxial to the traction wheel. The utility model makes full use of the characteristic of low noise of belt transmission; the utility model has the advantages of high transmission efficiency, good belt transmission maintenance, good belt transmission maintainability, lubricating oil saving, low manufacture cost and energy saving.
Description
The utility model relates to the elevator technology field, particularly a kind of strap drive elevator traction machine.
The belt towing machine is to do first order transmission with V-belt, tooth form synchronous belt as not the level transmission a kind of anodontia transmission towing machine, it is a kind ofly to be dragged by electrical motor, be delivered to traction sheave by this driving system rotatablely moving, the principle that traction sheave is used frictional transmission drives the steel rope that hangs on the wheel, steel rope is done being connected following manned or loading car pulling, following straight-line motion, speed difference according to elevator, can be designed to single-stage driving or twin-stage transmission to belt transmission system, the mode that present elevator traction machine adopts mainly usefulness be the tooth engagement systems, it comprises spur gear transmission, epicyclic gear transmission, the worm and gear transmission, the garden bevel drive, perhaps wherein both combinations, spur-geared shortcoming is the manufacturing expense height, noise ratio is bigger, though worm and gear transmission noise ratio is low little, but efficient is very low, wearing and tearing are big, their common shortcomings are closed transmissions, the transmission component gear, bearings etc. all are contained in one " fuel tank ", and the people can not be approaching under running condition, be not easy to maintenance, check that heat radiation and lubricant effect are also poor.
The purpose of this utility model provides a kind of noise and vibrations are little, high efficiency, the strap drive elevator traction machine that manufacturing expense is low.
The purpose of this utility model is to realize like this, it comprises electrical motor, brake disc, profile of tooth belt wheel, tooth form synchronous belt and traction sheave, it is characterized in that electrical motor is provided with little profile of tooth belt wheel, little profile of tooth belt wheel is given big profile of tooth belt wheel transmission of torque by cog belt, and big profile of tooth belt wheel is coaxial with traction sheave.
The utility model makes full use of the low characteristics of belt-driving noise, has the driving efficiency height, and the strap drive maintenance, repair are good, saves lubricating oil, the advantage of low cost of manufacture and energy savings.
Below in conjunction with accompanying drawing the utility model is further described,
Fig. 1 is the structural representation of single-stage driving strap drive elevator traction machine,
Fig. 2 is the structural representation of secondary driving band transmission elevator traction machine,
As shown in Figure 1, this single-stage driving strap drive elevator traction machine, comprise electrical motor 1, brake disc 2, profile of tooth belt wheel 3,5, tooth form synchronous belt 4 and traction sheave 6, electrical motor 1 is provided with little profile of tooth belt wheel 3, little profile of tooth belt wheel 3 is given big profile of tooth belt wheel 5 transmission of torque by cog belt 4, and big profile of tooth belt wheel 5 rotates with traction sheave 6 coaxial traction sheaves 6 and drives the elevator cage operation.
As shown in Figure 2, this secondary driving band transmission elevator traction machine, it comprises electrical motor 1, brake disc 2, profile of tooth belt wheel 3,5, tooth form synchronous belt 4 and traction sheave 6, electrical motor 1 are provided with little V-belt wheel 9, and little V-belt wheel 9 is given big V-belt wheel 8 transmission of torque by V-belt 7, big V-belt wheel 8 is coaxial with little profile of tooth belt wheel 3, little profile of tooth belt wheel 3 is given big profile of tooth belt wheel 5 transmission of torque by cog belt 4, and big profile of tooth belt wheel 5 is coaxial with traction sheave 6, and traction sheave 6 drives the operation of elevator car cab.
Claims (2)
