Description
Technical field
The present invention relates to a kind of clutch, particularly, relate in particular to a kind of disc type magnetic control variable-speed clutch that is used for machinery soft start and soft braking that can stepless speed regulation.
Background technique
At present, in jumbo, because movement parts has bigger inertia, therefore, in starting process,, will certainly cause starting torque excessive if acceleration is excessive, on the one hand, can cause greater impact to associated components, thereby need strengthen its mechanical strength greatly, increase machine weight and manufacture cost, on the other hand, also need bigger starting power, make driving power, not only increased manufacture cost much larger than proper functioning power, simultaneously, also reduced the power factor of power source, increased the wattless power loss, strengthened impact electrical network, even, because of the restriction of net capacity is difficult to start.
Soft start is by electric or mechanical mode, the startup acceleration of control machinery equipment, thereby the control starting torque makes it satisfying under the prerequisite that requires starting time, reduce starting torque, to save the manufacturing cost and use cost of machinery equipment, reduction reduces the influence to electrical network to the requirement of electrical network.Electric soft start generally is used for, the soft start of low-power equipment, and mechanical soft start generally is applied to the soft start of powerful device.Below, be example with powerful Belt Conveyors, illustrate that it is in the problem that opens, stops in the process to be brought:
When 1, conveyor starts:
(1) moment has increased motor power;
(2) increased the tension force of belt;
(3) increased the load of structural member;
When 2, conveyor stops:
(1) cause the flat belt localized stress low excessively, and the sag of belt even be torn;
(2) cause the high and low stress ratio in brake drum two ends excessive, make belt elevator on brake drum, skid.
