Abstract
The invention discloses a friction drive mechanism, which comprises a drive shaft and a driven shaft; the end part of the drive shaft is provided with a first friction cone wheel; the end part of the driven shaft is provided with a second friction cone wheel; the first friction cone wheel and the second friction cone wheel are in friction drive. The friction drive mechanism is characterized in that a coarse thread screw, a coarse thread nut and a key are arranged between the driven shaft and the second friction cone wheel from inside to outside in sequence; a compression spring is also arranged between the coarse thread nut and the second friction cone wheel; and preferably, a face, which is in friction contact with the driven shaft, of the drive shaft is provided with a force sensor. Use flexibility is relatively high, and further, the phenomenon that the service life of the mechanism is influenced by long-term overloaded operation is avoided.
Description
Technical field
The present invention relates to a kind of slip gear.
Background technology
Existing slip gear when overload condition occurs, friction cone pulley between produce relative sliding and cause mechanism can not normal rotation, the motility of use is poor.
Summary of the invention
For the problems referred to above, the present invention provides a kind of slip gear, uses motility higher, further, it is to avoid long-term overburden work and affect service life of mechanism.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, the present invention is achieved through the following technical solutions:
A kind of slip gear, including driving shaft and driven shaft, described driving shaft end is provided with the first friction cone pulley, the end of described driven shaft is provided with the second friction cone pulley, described first friction cone pulley and the second friction cone pulley frictional drive, it is characterized in that, be disposed with coarse thread screw rod, coarse thread nut and key between described driven shaft and the second friction cone pulley from inside to outside, between described coarse thread nut and the second friction cone pulley, be additionally provided with compression spring.
Preferably, described driving shaft and the face of driven shaft phase CONTACT WITH FRICTION are provided with force transducer.
Preferably, described driving shaft is vertically arranged, and described driven shaft is horizontally disposed with.
Preferably, described force transducer is strain pressure transducer.
The invention has the beneficial effects as follows:
Driving shaft drives the first friction cone pulley to be rotated, driven shaft is driven to rotate by the second friction cone pulley, key, coarse thread nut and coarse thread screw rod, wherein, when the load on driven shaft exceedes setting value, coarse thread nut slides and compression spring, compresses the first friction cone pulley and the second friction cone pulley makes frictional force increase, so that mechanism remains in operation, when load is less, then coarse thread nut reduces the pressure of compression spring so that the first friction cone pulley and the second friction cone pulley frictional force reduce.
Further, the concrete frictional force of force transducer monitoring, it is to avoid long-term overburden work and affect service life of mechanism.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of slip gear of the present invention;
The labelling implication of accompanying drawing is as follows:
1: driving shaft; 2: force transducer; 3: the first friction cone pulleys; 4: driven shaft; 5: the second friction cone pulleys; 6: coarse thread screw rod; 7: coarse thread nut; 8: compression spring;9: key.
Detailed description of the invention
