Description

Technical Field

[0001] The utility model relates to the field of torquers, and more specifically, to a friction plate type torquer which can protect connection equipment. Background Art

[0002] The friction plate torquer adjusts the rated torque by adjusting the height of the spring. When the resistance exceeds the rated torque, the body and the friction plate begin to slip, the drive shaft begins to idle, and power transmission stops, thereby protecting the equipment.

[0003] Chinese patent CN202867637U discloses a friction plate torquer, which belongs to the field of mechanical transmission. The friction plate torquer includes a bolt spring kit, a horn fork, a torquer body, an inner pressure plate and an outer pressure plate. One end of the horn fork is connected to the power input end or the output end. After the bottom of the other end of the horn fork is installed in a bushing, the torquer body is installed in the bushing; the two annular end faces of the torquer body are respectively provided with friction plates of the same number and shape; the inner pressure plate and the outer pressure plate fix the torquer body and the horn fork together through a plurality of the bolt spring kits. The beneficial effect of the utility model is that when the working resistance is greater than the rated torque set at the factory, the torquer body overcomes the friction of the friction plate, starts to rotate, and stops power transmission, which can be used to protect equipment and transmission shafts.

[0004] However, in actual use, the existing friction plate torquer mainly rubs against the two sides of the surface through the friction plate. The friction process will cause certain losses to the friction plate and the surface of the torquer body. However, when a large friction force cannot be generated, the torquer body and the friction plate need to be replaced at the same time, which is very costly. Utility Model Content
