Abstract
The utility model relates to a medium-low speed high efficient variable speed machine. The planetary wheel seat 2 connected with an output axle 1 transfer the revolution of a planetary cone pulley 3 to the output axle. The utility model has the advantages of big ratio of transmission, wide range of power transfering, strong bearing capacity of low speed, high mechanical efficiency and good starting performance. The utility model can be widely used for the production equipment of textiles, manufacture of building materials, pottery, packing, printing, chemical industry, and plastic processing.
Description
The utility model belongs to machinery, especially speed reducer and makes the field.
The prior mechanical speed changer, be subjected to the restriction of its reduction speed ratio,, need to be equipped with other step change transmission in addition and could obtain the required slow-speed of revolution in the extremely slow-revving occasion of need, make the axial dimension and the floor space of whole unit increase like this, also increased the cost of production of unit and made workload.
Above shortcoming in view of prior art, the purpose of this utility model is: design a kind of novel mechanical formula continuously variable transmission device of compact structure, make it have the advantage that the unit gear ratio is big, power transmits wide ranges, the low speed bearing capacity is strong, mechanical rate is high, starting performance is good.
The purpose of this utility model is to realize by following design.
In the stepless change body of being made up of housing, input shaft, output shaft, sun cone pulley, planetary cone wheel, speed ring, planet wheel seat etc., sun cone pulley and input shaft interlocking are in one, and the planet wheel seat is connected with input shaft.Arrange all on the planet wheel seat that number can only be around the planetary cone wheel of bearing pin rotation, the bearing pin of cone pulley is fastened on the planet wheel seat, adopts double needle roller supporting structure between cone and bearing pin.The bus of the big conical surface in the cone pulley outside is parallel with output shaft, and speed ring is close to this side and is installed.
For reaching bigger reduction speed ratio, above structure also can be done following change, input shaft passes the fixed cone wheel seat that is fixed on the housing, several can be distributed on the fixed cone wheel seat around the fixedly cone pulley that its bearing pin rotates, interlocking on input shaft sun cone pulley and planetary cone wheel and fixedly cone pulley be close to, the speed ring with interior double flange simultaneously and planetary cone wheel and fixedly cone pulley fit and install.
After adopting design as above, because sun cone pulley and planet wheel seat are connected as a single entity with input shaft, output shaft respectively, the rigidity height of retarder, transmitted power wide ranges (0.2-30kw), mechanical efficiency height (＞90%), adjustment range wide (1/4-1/90 stepless speed regulation) low speed bearing capacity are strong, the rotating accuracy height, starting performance is good.Can extensively be effectively applied in weaving, building materials, pottery, packing, plastic processing, Chemical Manufacture, printing and all kinds of production conveyor lines etc., in the low speed manufacturing mechanism.
Description of drawings is as follows:
Fig. 1: structural drawing of the present utility model.
Fig. 2: the double cone pulley schematic structure diagram of the utility model.
Below in conjunction with accompanying drawing structure of the present utility model and principle are described in further detail.
As shown in Figure 1, sun cone pulley 4 is one with the input shaft interlocking, planet wheel seat 2 is connected with output shaft 1, planet wheel seat 2 is evenly equipped with the planetary cone wheel 3 that number rotates around its bearing pin 9 only, bearing pin 9 securely is connected on the planet wheel seat 2,9 of cone pulley 3 and bearing pins adopt double needle roller supporting structure 10, and the bus of the big conical surface in cone pulley 3 outsides is parallel with output shaft, and speed ring 5 is close to this side and is installed.Permanent power motor drives input shaft and rotates, several the planetary cone wheels that the sun cone pulley of interlocking on input shaft drives with it closely contacts rotate, the outside of planetary cone wheel closely contacts with speed ring, when planetary cone wheel rotates, it is motionless that speed ring keeps, and its friction torque makes planetary cone wheel on one side around the bearing pin rotation, around sun cone pulley revolve round the sun on one side, its revolution speed passes to output shaft by planetary cone wheel seat wheel, thereby finishes deceleration-operation.Speed ring can follow the outside parallel shifted of star cone pulley, to obtain different variations, this be because, when speed ring follows the outer side shifting of star cone pulley, the geometric radius of planetary cone wheel and speed ring point of contact planetary cone wheel shaft centre line changes, respective change also takes place to the friction catch moment of planetary cone wheel in speed ring thereupon, thereby causes the rotation of planetary cone wheel and revolution speed to change, and finally makes the planetary cone wheel seat be delivered to the velocity variations of output shaft.In Fig. 1, speed ring is moved to the left, and the output shaft rotating speed is higher; Speed ring moves right, output shaft rotating speed step-down.Regulate the diverse location of speed ring, realize stable stepless speed regulation.
Fig. 2 is an another kind of structure of the present utility model, other parts and last similar.Input shaft 8 passes the fixed cone wheel seat 7 that is fixed on the housing, several do rotation, the fixedly cone pulley of not doing to revolve round the sun 6 is distributed on the cone pulley seat 7, the sun cone pulley 4 of interlocking on output shaft drives planetary cone wheel 3 and fixedly cone pulley 6 rotations respectively, has the speed ring 5 and planetary cone wheel 3 and fixedly cone pulley 6 applying installations of interior double flange.Because speed ring 5 is unfixing, speed ring rotates around output shaft with the linear velocity identical with fixing cone pulley 6, and the different point of contact of the flange of speed ring on fixing cone pulley 6 make the different rotational velocity of speed ring generation.The characteristics of this scheme are to have bigger slewing range.
Claims (2)
