Abstract
A rotary wheel for a ball pitching machine includes a wheel body and a resilient member engaged on an outer periphery of the wheel body. A shaft hole is provided in the wheel body for receiving a shaft of a motor of the ball pitching machine. The wheel body includes a spring portion arranged between the shaft hole and the outer periphery of the wheel body in a radial direction and including first and second bending portions both of which protrude from two sides of the wheel body respectively. When the rotary wheel is driven to turn by the motor, a frictional force of contact of the resilient member with a ball makes the ball shot outwardly, and the rotary wheel is not broken or damaged due to the spring portion compressed in the radial direction to absorb the impact energy.
Claims7
A rotary wheel for a ball pitching machine, comprising:
- a wheel body including first and second surfaces opposite along an axis and a shaft hole provided in the wheel body and adapted to be extended through by a shaft of a motor of the ball pitching machine, with the rotary wheel further including an annular spring portion formed between the shaft hole and an outer periphery of the wheel body in a radial direction perpendicular to the axis, with the spring portion including a first bending portion protruding outwardly from the first surface and a second bending portion protruding outwardly from the second surface of the wheel body, with each of the first and second bending portions capable of being compressed or stretched in the radial direction, and
- a resilient member engaged on the outer periphery of the wheel body.
