Common handwheels have an inner corrugated handwheel, a double spoke handwheel, a round rim handwheel, and a back corrugated handwheel.
These are described below:
Internal corrugated hand wheel material PF phenolic plastic. Anti-friction, anti-aging, insulation, temperature resistance, hardness, and bright surface.
The two-dimensional drawing of the round rim hand wheel is made of PF phenolic plastic material. Compared with the inner corrugated hand wheel and the back corrugated hand wheel, it is not suitable for the place where the force is large. The shape structure of the round rim hand wheel determines that it bears little force. Features.
Users can choose the right choice according to the working environment and the strength.
The double-wound handwheel is made of reinforced nylon or aluminum alloy.
The relatively inner corrugated handwheel of reinforced nylon material is more tough but not hard, and will be deformed for a short time when it is subjected to excessive force or external force, and will not be broken.
Compared with the former, the aluminum alloy material has strong hardness, bright surface but no insulation, and is not suitable for motor supporting products.
The only weakness is the fragility, which is fragile by heavy objects.
The national mechanical operating parts of the round rim hand wheel are implemented in the standard JB/T7273.5-1994 (GB4141.24-84, JB1356-73).
The material of the round rim hand wheel is PF phenolic plastic (bakelite, bakelite), the surface is bright, anti-friction, insulation, heat resistance and high hardness. Beautiful appearance.
The round rim hand wheel is machined according to the JB/T7273.5-1994 standard, and the inner hole optical hole keyway fixed keyway specifications are processed according to the provisions of GB1095-74.
The shape of the hand wheel is unchanged under the condition that the quality is guaranteed. The size of the inner hole and the keyway can be made according to customer needs.
The back corrugated handwheels are available in A and B models. The A-type side does not have a small rotating handle. When operating, the wave pattern on the back of the hand wheel can be used for anti-slip operation.
There is a small rotating handle on the B-type side, holding the small rotating handle 360° rotation in any direction while driving the hand wheel and mechanical operation.
Back corrugated national mechanical operating parts standard JB/T7273.8-1994 (JB3717.9-85). Made of PF phenolic plastic. The color standard is black.
