Abstract
Model utility provides a kind of Novel stepless speed regulation device, comprises speed-regulating part and transmission components, and described speed-regulating part comprises motor, driving shaft, driving wheel and stepless speed adjusting gear.Adopt stepless speed-regulating device to regulate the rotating speed of transmission pulley, in driving wheel and follower, be provided with spring assembly, regulate during stepless speed variator and can make driving wheel generation deformation, thus make follower generation deformation.Changed the rotating speed of transmission shaft by the deformation of driving wheel and follower, thus control the transmission speed passing belt pulley.This device adopts the wide type bearing support of integral type, ensure that in bearing support, concentricity is consistent, prevents transmission shaft at bearing support bias internal, therefore not easy to wear the and long service life of the bearing support of this stepless speed-regulating device.
Description
Technical field
The utility model relates to a kind of speed change gear, the Novel stepless speed regulation device that especially a kind of bearing support is integrated.
Background technique
Speed regulator is the widely used a kind of parts of machinery industry, be divided into step change and stepless change two kinds, stepless speed variator is compared with step change transmission, and its advantage is: can be in operation speed governing, can realize telecontrol thus even automatically to control, speed governing is convenient and strength-saving.Stepless speed adjusting gear can use variable-frequency motor to realize, or realizes stepless change by mechanical transmission, and pharmaceutical machine generally adopts mechanical transmission to realize stepless change.The arrangements for speed regulation applying to pharmaceutical machine had now generally adopt internal diameter identical two bearing supports to support and fixed conveyor axle, and therefore concentricity easily has deviation, and transmission shaft easily offsets in the process of running, thus the seat that very easily runs out bearing.
Model utility content
Problem to be solved in the utility model improves bearing support in background technique in existing stepless speed-regulating device problem easy to wear.
In order to overcome the above problems, the utility model provides a kind of Novel stepless speed regulation device, comprise speed-regulating part and transmission components, described speed-regulating part comprises motor, driving shaft, driving wheel and stepless speed adjusting gear, described motor is connected with described driving shaft, described driving wheel top movable is connected with a stepless speed adjusting gear, described driving wheel and stepless speed adjusting gear are sheathed on outside described driving shaft, described transmission components comprises follower, transmission shaft, bearing support and transmission pulley, described follower and driving wheel are located in same level, described follower and driving wheel all in be provided with spring assembly, described driving wheel is connected by belt with follower, one end of described transmission shaft is arranged with a follower, the other end of described transmission shaft is fixedly connected with a transmission pulley, the middle part of described transmission shaft is arranged with a bearing support.
Described bearing support adopts wide type shaft bearing, and described bearing support covers the area of described transmission shaft 4/5.
A kind of Novel stepless speed regulation device of the present utility model, stepless speed-regulating device is adopted to regulate the rotating speed of transmission pulley, owing to being provided with spring assembly in driving wheel and follower, therefore regulating stepless speed variator can make driving wheel generation deformation, thus make follower generation deformation.Changed the rotating speed of transmission shaft by the deformation of driving wheel and follower, thus control the transmission speed passing belt pulley.This device adopts the wide type bearing support of one, and can ensure that in bearing support, concentricity is consistent, thus ensure that transmission shaft not easily offsets, therefore the bearing support of this stepless speed-regulating device is not easy to wear, long service life.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of a kind of Novel stepless speed regulation device described in the utility model.
Marginal data: 1, motor; 2, driving shaft; 3, driving wheel; 4, stepless speed adjusting gear; 5, follower; 6, transmission shaft; 7, bearing support; 8, transmission pulley.
Embodiment
Below in conjunction with accompanying drawing, a kind of Novel stepless speed regulation device of the present utility model is described further.
As shown in Figure 1, the Novel stepless speed regulation device of the present embodiment, comprise speed-regulating part and transmission components, speed-regulating part comprises motor 1, driving shaft 2, driving wheel 3 and stepless speed adjusting gear 4, motor 1 is connected with driving shaft 2, driving wheel 3 top movable is connected with a stepless speed adjusting gear 4, driving wheel 3 and electrodeless speed regulator 4 are sheathed on outside driving shaft 2, transmission components comprises follower 5, transmission shaft 6, bearing support 7 and transmission pulley 8, follower 5 and driving wheel 3 are located in same level, follower 5 and driving wheel 3 all in be provided with spring assembly, driving wheel 3 is connected by belt with follower 5, one end of transmission shaft 6 is arranged with a follower 5, the other end of transmission shaft 6 is fixedly connected with a transmission pulley 8, the middle part of transmission shaft 6 is arranged with a bearing support 7.
In the present embodiment, driven by motor driving shaft rotates, and driving shaft drives driving wheel to rotate; Driving wheel is rotated by belt drive follower, and follower drives drive axis; Bearing support supporting shaft, prevents rotatingshaft from offseting; Drive axis drives transmission pulley to rotate, driving mechanical equipment work thus.In the present embodiment, by the motion speed regulating stepless speed adjusting gear to carry out control apparatus.When rotating stepless speed adjusting gear, the diameter of driving wheel increases, due to driving wheel and follower all in be provided with spring, length again due to belt is certain, therefore when driving wheel diameter increases, follower can by built-in spring generation deformation, and diameter reduces, the faster rotational speed of follower thus, thus the rotating speed of transmission pulley is accelerated.When stepless speed adjusting gear upwards rotates, driving wheel internal diameter reduces, and follower internal diameter increases, and secondary speed is slack-off, thus makes the rotating speed of transmission pulley slack-off.
In the present embodiment, bearing support 7 adopts wide type shaft bearing, and bearing support 7 covers the area of transmission shaft 4/5.Adopt the integral bearing seat that area coverage is large, can ensure that in bearing support, concentricity is consistent, thus ensure that transmission shaft not easily offsets, decrease the friction between transmission shaft and bearing support, make in bearing support not easy to wear, thus extend the working life of bearing support.
The utility model is not limited to above embodiment and conversion.
