Abstract

The utility model provides a novel speed variation hoister. The utility model has the advantages of large speed variation range, simple structure, low cost, no loss of energy consumption during work, convenient operation, and besides, the utility model is popular with users. The utility model is characterized in that a speed variator which is driven by double motors is formed by the combination of a fixing shaft wheel train and a planet wheel train, and an output shaft of the speed variator is connected with a winding drum. Because a drum-shaped stick pin is used, the utility model can simultaneously transmit torque and bear radical pressure, and the utility model also has a function of automatic correction.

Description

Internal gear type planetary speed-change lift with two motors

The utility model is a kind of later-model variable-speed winch, is applicable to the occasion that skyscraper building site, mine, mine etc. have higher requirements to the speed adjusting performance of winch.

Variable-speed winch at present commonly used mainly contains three kinds of DC machine crosstalk resistive speed, hydraulic-driven speed change and alternating-current motor/AC motor eddy-current brake speed changes, wherein DC machine crosstalk resistive speed winch gearshift performance is better, but need direct supply and resistance box, complete machine structure is huge, manufacturing cost is very high, owing to be that power consumption is bigger when therefore working with power consumption principle speed change; The use cost height; Hydraulic winch complex structure, huge, the Hydraulic Elements requirement on machining accuracy is higher, the manufacturing cost height; Eddy current brake type winch, because of also need to be furnished with whirlpool and resistance box outside alternating-current motor/AC motor, manufacturing cost is also higher, owing to be that power consumption is bigger during work with resistance braking principle speed change, can not long-time running after the speed change, use cost is higher.

The utility model overcomes the deficiency of above-mentioned several types and the design-calculated new architecture, being characterized in that the big And of (1) speed range can be with is worn over speed change step by step reposefully in service, thereby gearshift performance is better, (2) simple in structure, manufacturing cost is lower, and the work of (3) speed change the time not having the power consumption loss, and power saving, use cost are low.

The utility model utilization speed superposition principle is carried out speed change, and in the change-speed box part, the compound gear train version that adopts internal-gear type planet circular system and expansion equation fixed shaft gear train to combine is to reach the purpose of speed superposition and power superposition.

Do more detailed explanation and introduction below in conjunction with accompanying drawing.

I, II are single-speed motors among Fig. 1, reel 17, speed-changing gear box 18;

Change speed gear box middle gear 1～6 is formed a component fixed shaft gear train among Fig. 2, and Fig. 2 is 18 cutaway views that remove case lid among Fig. 1;

Internal tooth shell 7 among Fig. 3, satellite gear 9, tumbler shaft 10, sun wheel 11 are formed a planet circular system; Fig. 3 is the axial cutaway view of planetary mechanism in internal tooth shell spare 7 among Fig. 2 and the part 7,

Fig. 4 is a K-K part sectional view among Fig. 1;

Be processed with internal tooth and external tooth on the internal tooth shell 7 simultaneously, it is with after end cap 8 usefulness bolted connections become an integral body, be bearing on the tumbler shaft 10.

Sun wheel is a dual gear, and the one side is a crowned teeth, and opposite side is straight-tooth or helical teeth, and it does not have fixing position in planet circular system, be in quick condition fully;

Limit plug 12 by bearing installation in tumbler shaft, for sun wheel 11 is made axial location; Be processed with the duplex internal tooth on the internal tooth casing 13, be sleeved on sun wheel 11 and the input shaft 14, it makes axial location for sun wheel 11, and also transfer torque and work are aligned automatically simultaneously;

Input shaft 14 is contained in the tumbler shaft 10 by bearing carrier ring, and its one is processed with crowned teeth, and crowned teeth is sleeved in the geared sleeve 3, is a radial support of internal tooth casing;

The joining part of transmission output shaft of the present utility model and reel, adopt half rod pin coupler structure form of tape drum shape, shown in figure four: cydariform half rod pin coupler, by axle sleeve 15, cydariform rod pin 16 is formed with reel, axle sleeve 15 is installed on the output shaft of change-speed box by key, be unified into an integral body with mouth, the outer garden of axle sleeve is on week, be processed with several half garden connected in stars, the garden arc dia of groove is identical with rod pin diameter, the interior garden of one end of reel is on week, also be processed with half garden connected in star, the garden arc dia of groove is identical with rod pin diameter, and the groove number is identical with axle sleeve, reel is contained on the axle sleeve by cydariform rod guide, and reel and axle sleeve be direct contact not.

Working process of the present utility model is as follows: referring to Fig. 1, and when motor II and motor I switched in opposite, sun wheel 11 and internal tooth shell 7 switched in opposite, by the speed superposition principle as can be known, rotating speed subtracts each other, and giving the rotating speed of reel through gear 3～6 is low speed; Wherein only start a motor, during another motor stop, it is middling speed that reel gets rotating speed; If motor II and motor I turn to when identical, sun wheel 11 turns to identical with the internal tooth shell, the rotating speed addition, the rotating speed of reel is at a high speed, as long as suitably select for use the rotating speed ， And of two single-speed motors suitably to select the number of teeth of each gear in the compound gear train, just can obtain predetermined several work speed, if it is double-speed motor that a motor is arranged, then obtain 7 kinds of work speeds.

The internal gear type planetary speed-change lift with two motors that the utility model provides to people has good gearshift performance, its slewing range is big, be other any type institute can't compare like, high efficiency, electricity saving and energy saving, whole operating process steadily, safety, reliable, firmly get users' praise.
