Abstract
The utility model relates to a traction engine for elevators, which is characterized in that the conventional eccentric sleeve is removed, and a fixed eccentric shaft is used for regulating the meshing clearance of a worm wheel and an endless screw. Compared with the traditional traction machine, the utility model has the advantages of simple and convenient adjustment of meshing clearance or maintenance, simple and convenient installation and debugging, easily ensured machining precision of the eccentric shaft, low cost, high transmission accuracy, stable transmission and strong versatility, and the utility model is an ideal traction machine of passenger-goods elevators.
Description
The utility model relates to a kind of actuating device of elevator, particularly a kind of elevator traction machine.
Existing elevator traction machine is by the back lash between eccentric bushing adjustment worm gear, the worm screw.But because eccentric bushing is a pair of use, requirement on machining accuracy is very high, and during the adjusting play, the side-play amount that two eccentric bushings produce must guarantee unanimity, otherwise cause the main shaft of towing machine to tilt easily, influence transmission accuracy and stationarity, it is cumbersome and inconvenient adjusting the back lash with eccentric bushing in practice.
The purpose of this utility model is the defective that overcomes above-mentioned prior art, provides a kind of and is easy to adjust the worm and gear back lash, and working accuracy easy to reach elevator traction machine.
The utility model is achieved by the following technical solution: towing machine is made up of support, worm gear, worm screw, traction sheave, drg, electrical motor and main shaft, and main shaft is an eccentric shaft, and is anchored on the support of support.Bearing is housed on the main shaft, and bearing is placed in the drive sleeve, and worm gear and traction sheave are loaded on the drive sleeve.The spindle nose of rotating spindle, main axis rotation, since eccentric, make the displacement of the worm gear generation warp-wise that is loaded on the main shaft, thus the gap of adjustment and worm mesh.
The utility model is compared with traditional towing machine, has following advantage: it is simple and convenient 1, to adjust the back lash; 2, be easy to assembling maintenance worm and gear; 3, the working accuracy of main shaft guarantees easily; 4, accuracy of mesh height, stable drive; 5, highly versatile.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a part sectional view of the present utility model.
Below in conjunction with drawings and Examples the utility model is further elaborated.
With reference to Fig. 1, towing machine is made up of support (1), worm gear (2), worm screw (3), traction sheave (4), drg (10), electrical motor (6) and main shaft (7).Electrical motor (6) is fixed on the support (1) by counter flange dish (5), electrical motor (6) drives worm screw (3) by the rubber shaft coupling and rotates, worm screw (3) and worm gear (2) engagement drive worm gear and rotate, and drive traction sheave (4) transmission by drive sleeve.
With reference to Fig. 2, main shaft (7) is an eccentric shaft, and the axis of axle supported end is not adorned the dead in line of bearing with the stage casing, and has an eccentric distance e.Bearing (9,13) is loaded on the stage casing of main shaft (7), and is placed in the drive sleeve (8), and worm gear (2) and traction sheave (4) are loaded on the two ends of drive sleeve (8) respectively.Main shaft (7) does not rotate, and is fixed on the support of support (1) by fastener (11,12).
When needs are adjusted the back lash of worm gear (2) and worm screw (3) (not drawing among the figure), unclamp fastener (11,12), rotate spindle nose, main shaft (7) rotation, because the accentric cause, worm gear (2) just produces radial displacement, offset by acyclic homologically trioial to maximum eccentricity amount e, (e can be processed as 1-2mm as required) makes worm gear (2) and worm screw (3) reach best engagement, guarantees the accurate, steady of transmission.
The embodiment motor can be selected the YTD serial motors for use, as YTD-225M
1Power is 7.5kw, 11kw, YYTD-15,15kw or Y160M, the electrical motor of power 7.5kw, 11kw, be the commonality that realizes that motor main shaft connects with support (1), increased a counter flange (5), it all can connect the electrical motor of the different location diameter of axle with same support (1), drives worm screw (3) and rotates.Worm screw (3) can be adopted single head or double-thread worm, and traction sheave (4) also can be selected 4 grooves or 5 grooves for use, and this can determine according to the command speed of nominal payload and elevator.Adopt different parts, the utility model can have load-carrying 1000Kg, 0.5m/s speed or 1000Kg, 1m/s speed, 1000Kg, the towing machine of multiple models such as 1.5m/s speed or 500Kg load-carrying, 0.5m/s.
Claims (2)
1, a kind of elevator traction machine is made up of support, worm gear, worm screw, traction sheave, drg, electrical motor, main shaft, it is characterized in that: main shaft (7) is an eccentric shaft, is anchored on support (1) support.
2, elevator traction machine according to claim 1 is characterized in that bearing (9,13) is loaded on the main shaft (7), and is placed in the drive sleeve (8) that worm gear (2) and traction sheave (4) are contained on the drive sleeve (8).
