Abstract
A sprocket is provided, the sprocket having a body with a central opening for engaging a shaft and rotating about an axis. The sprocket has a plurality of teeth disposed around the periphery of the body. The teeth are angularly spaced about the axis such that each tooth is spaced from the adjacent teeth by a first opening. Each tooth has a belt-contacting surface which is convex in shape such that the outer-most periphery of the sprocket is generally circular. The belt-contacting surfaces of the teeth guide the belt around the periphery of the sprocket in order to minimize the ability of the belt to buckle.
Claims17
A sprocket for a non-modular belt having transverse ribs, the sprocket being disposed on a shaft and configured to rotate about an axis coincident with the shaft, the sprocket comprising:
- a body comprising:
- a central opening for receiving the shaft;
- a plurality of teeth disposed in pairs, the pairs being angularly spaced about the axis, wherein each pair of teeth being spaced from adjacent pairs of teeth by a first opening, and wherein each tooth in each pair of teeth being spaced from the other tooth in the pair by a second opening;
- and
- wherein a belt-contacting surface of each tooth is radially convex about the axis such that the entire outer-most periphery of the body, as defined by the belt-contacting surfaces of the teeth, is generally circular for preventing buckling of the belt.
A sprocket for a non-modular belt, the sprocket being disposed on a shaft and configured to rotate about an axis coincident with the shaft, the sprocket comprising:
- a body comprising:
- a central opening for receiving the shaft;
- a plurality of teeth, the teeth being angularly spaced about the drive axis, wherein each tooth is spaced from adjacent teeth by a first opening;
- and
- wherein a belt-contacting surface of each tooth is radially convex about the axis such that the entire outer-most periphery of the body, as defined by the belt-contacting surfaces of the teeth, is generally circular for preventing buckling of the belt.
A conveyor belt system comprising:
- a sprocket comprising:
- a body comprising:
- a central opening for receiving a shaft, the shaft configured to rotate about a longitudinal axis;
- a plurality of teeth disposed in pairs, the pairs being angularly spaced about the axis, wherein each pair of teeth being spaced from adjacent pairs of teeth by a first opening, and wherein each tooth in each pair of teeth being spaced from the other tooth in the pair by a second opening;
- and
- wherein a belt-contacting surface of each tooth is radially convex about the axis such that the entire outer-most periphery of the body, as defined by the belt-contacting surfaces of the teeth, is generally circular for preventing buckling of the belt;
- a non-modular belt configured to contact the belt-contacting surfaces of the teeth of the sprocket;
- a plurality of transverse ribs disposed on the belt and configured to engage the second openings of the sprocket as the belt is conveyed around the sprocket.
