Abstract
The utility model discloses a speed reducer which relates to a gear transmission device used for transmitting the rotary motion at a changeable speed ratio. The speed reducer adopts the technical proposal that the speed reducer comprises an input shaft and two output shafts, a planetary gear is connected with an eccentric sleeve on the input shaft and is meshed with an internal gear, a clip key is arranged between an inner hole at the toothless end of the internal gear and a cylindrical surface on the end head of an intermediate shaft, and gears on the intermediate shaft are respectively meshed with the gears on the two output shafts at the two sides of the intermediate shaft. The planetary gear is connected with the eccentric sleeve on the input shaft and is meshed with the internal gear, the clip key is arranged between the inner hole at the toothless end of the internal gear and the cylindrical surface on the end head of the intermediate shaft, the gears on the intermediate shaft are respectively meshed with the gears on one output shaft and intermediate gears on the intermediate wheel shaft, and the intermediate gears are meshed with the gears on the other output shaft adjacent to the intermediate gears. The speed reducer is mainly used for the deceleration of hoist cranes.
Description
Technical field:
The utility model relates to a kind of gear drive that is used for the variable gear ratio conveying rotary motion, particularly a kind of speed reducer.
Background technique:
Existing double output shaft speed reducer is to adopt the transmission principle of gear outer gearing to realize slowing down, reduction speed ratio is less, and will take the multimachine logotype or adopt Low speed electric motor to realize for slow-speed of revolution output, like this volume of speed reducer big, take up room greatly and cost high.
Summary of the invention:
The purpose of this utility model provides the speed reducer that a kind of reduction speed ratio is big and the little cost of volume is low.The technical solution of the utility model is, a kind of speed reducer, comprise input shaft and two output shafts, it is characterized in that: planetary pinion is connected with eccentric bushing on the input shaft and meshes with internal gear, be provided with the card key between the cylinder of the endoporus of the no increment of this internal gear and jack shaft termination, the gear on this jack shaft respectively with two output shafts of its both sides on gear engagement.A kind of speed reducer, comprise input shaft and two output shafts, it is characterized in that: planetary pinion is connected with eccentric bushing on the input shaft and meshes with internal gear, be provided with the card key between the cylinder of the endoporus of the no increment of this internal gear and jack shaft termination, gear on this jack shaft respectively with an output shaft on gear and Jie's gear engagement on the axle of carrier pulley, the gear engagement on another output shaft that this Jie's gear is adjacent.Input shaft is provided with balancing disk.The utility model has the little and low advantage of cost of the big and volume of reduction speed ratio compared with the prior art.
Description of drawings:
Fig. 1 is the plan view of the utility model speed reducer, and Fig. 2 is the A-A turnover sectional view of Fig. 1, and Fig. 3 is the B-B sectional drawing of Fig. 2.
Embodiment:
In conjunction with above accompanying drawing the utility model is elaborated, in order to obtain big retarding ratio and the little speed reducer of volume, engagement transmission mechanism is realized in adopting.Being provided with planetary pinion 3 on the eccentric bushing 2 of input shaft 1 is meshed with internal gear 4, the endoporus of the no increment of this internal gear is connected with jack shaft 6 mutually by card key 5, gear 7 on the jack shaft respectively with output shaft 10 on gear 13 and Jie's gear 8 on the axle of carrier pulley 9 be meshed, this Jie's gear simultaneously with another output shaft 12 on gear 11 engagements.The engaging speed reducer structure has been realized two different rotating speeds and the different slow-speed of revolution output that turns in this.When two output shafts in the same way with rotating speed the time, do not establish in the engaging speed reducer structure in this axle of carrier pulley and on Jie's gear, by the gear on the jack shaft 7 simultaneously with two output shafts on gear engagement get final product.
Deceleration principle of the present utility model is, drive planetary pinion by eccentric bushing for input shaft rotational speed and torque by electric-motor-driving and make eccentric motion, internal tooth crop rotation slow-speed of revolution centering is rotated, and by the rotation of card key drive jack shaft, gear driven output shaft on the jack shaft rotates, and Jie's gear by axle of carrier pulley makes and above-mentioned output shaft backward rotation another output shaft, by change gear and with the output shaft gear number of teeth of its engagement, can make two output shafts have different rotating speeds.Engaging speed reducer can be realized up to the reduction speed ratio more than 200 in this, if adopt engagement driving in the secondary, then reduction speed ratio is bigger.Owing to adopt eccentric planetary pinion, its eccentric force can make speed reducer produce vibration, is overcome for avoiding this vibration that Balance disc 14 is set on input shaft.The utility model not only has the advantage that reduction speed ratio is big, volume is little, and the economize on electricity running steadily.
