Abstract
An anti-skid transmission belt wheel belongs to a transmission, is composed of a motor, an infinite variable speed belt, a conical pulley and a driven wheel, and is characterized in that the conical belt wheel is composed of a movable conical disc, a conical disc, a spring and limiting steel ball; the movable conical disc is fixed on a wheel center of the conical disc by the limiting steel ball via a pressure spring; the spring is mounted on the outer side of the movable conical disc; a variable-frequency governor is mounted on the motor. According to the utility model, the pulley is driven by adopting the conical disc and the infinite variable speed belt, so that equipment is surely stable and free from skidding during running, the transmission efficiency of the equipment is effectively ensured, the constant transmission ratio of the initial velocity running and normal running is ensured, in addition, a safety clutch is mounted on the pulley, the conical disc on the movable pulley can be automatically and axially moved when the equipment is in overload, the motor is idle, and the service life of the motor is ensured.
Description
Technical field
The utility model belongs to a kind of transmission device, is specifically related to a kind of automatic belt type stepless change control pulley arrangement.
Technical background
Traditional stepless change pulley arrangement, because stepless change belt wheel is to guarantee certain drive diameter by spring force, therefore the running speed of moment is inconstant after starting, cause equipment rotary speed unstabilization fixed, in the time that equipment pause is restarted, stepless change belt wheel one end cone dish, because being axially movable, often causes cvt belt distortion in belt wheel, and variable velocity zone and speed change belt wheel easily wear and tear; In the time that equipment enters standstill state by running, motor is braked motor by magnetic clutch adhesive, and equipment is due to inertia, and motor is had to an impact force, often causes motor to burn out.Very easily make movable cone mill on speed change belt wheel damage, even fracture.The problems referred to above cause operating rate lower, and member replacing is frequent, and maintenance cost is larger.
Summary of the invention
The purpose of this utility model is for described defect above, provides a kind of simple in structure, anti-skidding drive pulley that can stable drive speed.
The purpose of this utility model is achieved by the following technical programs.
A kind of anti-skidding drive pulley, by motor, cvt belt, conical pulley, driven wheel forms, it is characterized in that, described conical pulley forms by moving cone dish, cone dish, spring and spacing steel ball, in the heart, spring fitting is in mobile cone dish outside for the wheel that mobile cone dish is fixed on cone dish by spacing steel ball by stage clip; On described motor, variable-frequency governor is installed.
Working principle of the present utility model is: when equipment meets when overload, the active force that mobile cone dish overcomes spring moves axially laterally and departs from cone dish, thereby makes empty load of motor.When equipment in normal state time shift mantle dish owing to being subject to the active force of spring, spacing steel ball self-return is to boring on the groove of the plate wheel heart, mobile cone dish automatically resets.
The utility model is by main of former transmission system, be the AC motor (N=0.73kw of band brake, n=925r/min) electromagnetic braking partial cancellation, in electric control cubicle, install a variable-frequency governor additional, and seal in Electric Machine Control circuit, each like this when running into equipment voluntarily or artificially need to shutting down, all will automatically carry out closing control to motor by variable-frequency governor, reduce the impact force of motor, extend greatly the working life of motor, in the time of needs speed-raising or deceleration, need only on variable-frequency governor, input corresponding data simultaneously, just can realize acceleration or deceleration object, greatly facilitate operation.
The beneficial effects of the utility model are: the utility model has adopted belt-type stepless speed control apparatus, as long as input corresponding frequency on variable-frequency governor, equipment rotating speed just can be changed, due to belt wheel adopt conical disc and cvt belt transmission, therefore equipment can guarantee steadily non-slip in the running, effectively assurance equipment transmission efficiency, initial velocity running and the constant velocity ratio that runs well are guaranteed, on belt wheel, safety clutch device is housed simultaneously, when meeting overload situations, equipment can move the cone dish on belt wheel by automatic axial again, make motor idle running, guarantee motor working life.
Accompanying drawing explanation
Fig. 1 is the utility model overall schematic.
Fig. 2 is the structural representation of the utility model conical pulley.
In figure, 1 motor, 2 conical pulley, 3 spacing steel balls, 4 springs, 5 cvt belts, 6 driven wheels, 7 variable-frequency governors, 8 cone dishes, 9 move cone dish.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of anti-skidding drive pulley, by motor 1, cvt belt 5, conical pulley 2, driven wheel 6 forms, described conical pulley 2 is made up of mobile cone dish 9, cone dish 8, spring 4 and spacing steel ball 3, in the heart, spring 4 is arranged on mobile cone and coils 9 outsides the wheel that mobile cone dish 9 is fixed on cone dish 8 by spacing steel ball 3 by stage clip; On described motor 1, variable-frequency governor 7 is installed.
Working principle of the present utility model is: when equipment meets when overload, the active force that mobile cone dish 9 overcomes spring 4 moves axially laterally and departs from cone dish 8, thereby makes empty load of motor.When equipment in normal state time shift mantle dish 9 owing to being subject to the active force of spring 4, spacing steel ball 3 self-returns coil to cone on the groove of 8 core wheels, mobile cone dish 9 automatically resets.
The utility model is by main of former transmission system, be the AC motor (N=0.73kw of band brake, n=925r/min) electromagnetic braking partial cancellation, in electric control cubicle, install a variable-frequency governor 7 additional, and seal in Electric Machine Control circuit, each like this when running into equipment voluntarily or artificially need to shutting down, all will automatically carry out closing control to motor by variable-frequency governor 7, reduce the impact force of motor 1, extend greatly the working life of motor, in the time of needs speed-raising or deceleration, need only on variable-frequency governor 7, input corresponding data simultaneously, just can realize acceleration or deceleration object, greatly facilitate operation.
