Abstract
A split sprocket with quick locking mechanisms is made of non-metallic components. The split sprocket is coupled to a shaft element by removable wedge members disposed between the sprocket's half members. Key members, in conjunction with set screws, secure the wedge members and prevent the sprocket's half members from tilting about the shaft element. The wedge members maintain a uniform pitch diameter of the sprocket's teeth by preventing contact between the half sprocket members.
Claims14
A split sprocket wheel for mounting on a shaft comprising:
- (a) a pair of half, essentially semi-circular, sprocket members, each including:
- (1) a first major face;
- (2) a second opposite major face;
- (3) a plurality of radially extending teeth;
- (4) a pair of openings extending from said first face to said second face and located on opposite sides of an axis of rotation;
- and
- (b) removable coupling means, disposed through the openings, for urging and rigidly securing said half sprocket members around the shaft to form said sprocket wheel.
A split sprocket wheel for mounting on a shaft and for engaging a conveyor chain, comprising:
- (a) a pair of half, essentially semi-circular, sprocket members, each including:
- (1) a first major face;
- (2) a second opposite major face;
- (3) a plurality of radially extending teeth for engaging said chain;
- (4) a pair of openings extending from said first face to said second face and located on opposite sides of an axis of rotation;
- (b) a key member;
- (c) a set screw;
- (d) a wedge member, disposed through the openings, for urging and rigidly securing said half sprocket members around the shaft to form said sprocket wheel having a first aperture, perpendicular to the axis of rotation, for receiving said key member and a threaded aperture, perpendicular to and extending through to the first aperture, for receiving said set screw.
