Catch for rollers wound onto roller shafts - has guide compartment formed by flat surface of ratchet wheel along which locking piece rolls

摘要

The guide compartment (27) is formed by the flat guide surface (25) of the ratchet wheel (11) running parallel to the pivot axle, and the inside curve of the housing (5). The locking piece (29) rolls along the guide surface (25) at rotational speeds lower than the catch rotational speed underneath the stop piece (31). The ratchet wheel (11) can be an equilateral polygonal or square in shape. The locking piece (29) are spherical in shape. The stop piece (31) moves radially to the symmetrical cam fitting into the housing (5). The stop (31) moves radially to the axle of the ratchet wheel (11) and is fixed to the housing (5). The housing (5) has at least two fixture pins (43) protruding axially from one of the front surfaces (21). The pins (43) are inserted through holes (45) in the assembly flange (37) parallel to the front side (21) and are contained in elastic linings (49).
