Abstract
The utility model relates to a main transmission device of a comber. A two-speed motor 2 is arranged on a large base plate of a geared head 1; a main transmission shaft 7 is arranged in a bearing hole of the geared head; a triangle belt pulley 3 which is arranged on an output shaft of the two-speed motor 2 is connected with a triangle belt pulley 6 which is arranged on the main transmission shaft 7 via a triangle belt 4 which is connected with a tension wheel 5 for tension. After the two-speed motor is adopted to replace an auxiliary and a main motors, the device has the advantages of convenient operation and long service, cancelling reduction boxes, reducing processing difficulty and manufacturing cost.
Description
The utility model relates to a kind of combing machine main drive.
External Design for Combing Machine Main Transmission Mechanism adopts the primary and secondary motor more, promptly adopts a big motor, and power is 4.6kw, and rotating speed 1400rpm is called female motor.Also adopting a small machine power is 0.83kw, and rotating speed 1310rpm is called sub-motor.The motion of female motor can directly be exported, and drives the final drive shaft rotation by pulley concial disk, V belt.And the motion of sub-motor behind a reduction box, still by female motor output shaft output low speed, thereby is satisfied the low speed crawl of combing machine, the periodicity conversion requirement of the high-speed cruising → low-speed motion → high-speed cruising behind the low rate start.Be 30 minutes at a high speed transformation period, 10 seconds of low speed.Sub-motor is 1: 7.8 with female motor output speed ratio.
When sub-motor gets electric operation, female motor dead electricity, sub, female electromotor brake is all thrown off, and the electromagnetic clutch adhesive in the reduction box combines as a whole with female motor output shaft, output low speed.Female motor gets when electric, sub-motor dead electricity, and its brake braking, and the electromagnetic clutch in the reduction box is thrown off, and female motor output shaft output is at a high speed.The equal dead electricity of sub, female motor, sub, female electromotor brake braking.Brake, female motor all adopts the cone pulley braking, on manufacturing technique, and than the ordinary three-phase synchronous complexity, the cost height.The pressure of brake utilizes a pressing spring to produce.That is to say that when sub-motor or the operation of female motor, the electromagnetic clutch in female motor all needs adhesive, with the pressing spring compression, and female electromotor brake is thrown off.So just exist the interior electromagnetic clutch suction of female motor and the match selection of pressing spring bounce, otherwise will cause the operation under the half braking state, perhaps because the electromagnetic clutch volume increases, that is motor appearance and size strengthens, and increases power consumption simultaneously.
Along with long-term continuous operation and frequent braking, the glue ring wearing and tearing on the cone pulley brake are strengthened, the degradation failure of spring force in addition, the precision of braking and reliability are also more and more low, have influenced full machine reliability of operation and stability.Working strength and the expense of maintenance, maintenance have been increased simultaneously.
The purpose of this utility model is exactly the deficiency that exists at prior art, and a kind of combing machine main drive that is replaced the primary and secondary motor by double-speed motor is provided.
The purpose of this utility model can realize by following measure:
A kind of geared head (1) that includes, pulley concial disk (3), V belt (4), expansion tightening wheel (5), the combing machine main drive of final drive shaft pulley concial disk (6) and final drive shaft (7), double-speed motor (2) is arranged on the big base plate of geared head (1), final drive shaft (7) is arranged in the top dead eye of geared head (1), be installed on double-speed motor (2) output shaft pulley concial disk (3) be installed in final drive shaft (7) on pulley concial disk (6) between connect with V belt (4), also be connected with the expansion tightening wheel (5) that is used for tensioner on the V belt (4).
The performance indications of described double-speed motor (2) are as follows: stator, rotor slot-number ratio are 72:66; Adopt 4 grades, 24 grades stator double windings; Carry dry type monolithic electromagnetic brake; 380V/50HZ, 440V/60HZ.
The utility model compared with prior art has the following advantages:
Combing machine is the precision equipment that a kind of transmission is had relatively high expectations, and requires two speed on the technology, and full machine will be braked when out of service.On the basis of fully calculating, chosen the double-speed motor of 4 utmost points/24 utmost points, overcome shortcoming sub, female motor, guaranteed enough staring torques and running moment.Easy to use, the life-span is long, has cancelled reduction box, has reduced difficulty of processing and manufacturing cost.On the structure of motor, still kept the characteristics of asynchronous machine, and increased electormagnetic braking sytem.
Description of drawings is as follows:
Fig. 1 is a structural representation of the present utility model.
Be described in further detail by embodiment below in conjunction with accompanying drawing:
The combing machine main drive is made up of this case 1, double-speed motor 2, pulley concial disk 3, V belt 4, expansion tightening wheel 5, final drive shaft pulley concial disk 6 and final drive shaft 7.Double-speed motor 2 is installed on the big base plate of geared head 1, final drive shaft 7 is installed in the top dead eye of geared head 1, be installed on double-speed motor 2 output shafts pulley concial disk 3 be installed in final drive shaft 7 on pulley concial disk 6 between connect with V belt 4, also be connected with the expansion tightening wheel 5 that is used for tensioner on the V belt 4.
The performance indications of double-speed motor (2) when reality is made are as follows: stator, rotor slot-number ratio are 72:66; Carry dry type monolithic electromagnetic brake; 280V/50HZ, 440V/60HZ; The extremely two stator winding in selected 4 utmost points/24,4.7kw/0.8kw adopts mouse cage from fanning cold type.Main performance is as follows:
This double-speed motor actual motion is after 24 utmost points move 4 seconds, switches to 4 utmost points operation 30 minutes, transfers 24 utmost points operation 10 seconds again to, switches to 4 utmost points operation 30 minutes again, moves continuously with this rule.When machine breaks down when maybe needing to shut down, the motor dead electricity, existing side by side, it is moving to scribe.In the moment of cutting off motor power, the fixed magnetic field of the rotating excitation field of asynchronous machine and DC injection braking coil interacts, and rotor is checked rapidly.This double-speed motor is from appearance and size and install and all be better than the primary and secondary motor.The mounting structure pattern meets the FZ99006-92 standard.
This electric machine casing is to design on the 160mm support at former height of center, and volume is little, compact conformation, and electric machine main shaft does not have play, has significantly reduced the wearing and tearing of V belt.Adopt electromagnetic braking, the braking life-span is long, and braking moment is big, and it is reliable to be active in one's movements, and has reduced down time, has improved the operational efficiency of complete machine, through operation practice continuously, and complete machine operation balance, temperature rise is low, and noise is little, and Installation and Debugging are convenient, and cost is low.
