Title: TRANSMISSION DEVICE AND CORNER-TURNING MECHANISM FOR RACK THEREOF
Abstract:
A transmission device and a corner-turning mechanism for a rack. The corner-turning mechanism for a rack comprises an input pinion (10) and a rack turning assembly (20), wherein the rack turning assembly (20) comprises a plunger (21) and a plurality of rack units (22); the plunger (21) is a straight strip and moves along a linear trajectory; the rack unit (22) adjacent to the plunger (21) is connected to the trailing end of the plunger (21) in a tilted manner; other rack units (22) are sequentially connected to the trailing ends of the preceding rack units (22) in a tilted manner; and when the rack units (22) are engaged with the input pinion (10), the rack units (22) rotate to align with the plunger (21). The flexible turning of the turning mechanism is ensured by the rotatability of the rack units (22), and the reciprocating rotation of the input pinion (10) is converted into the reciprocating translation of the plunger (21), thereby enabling the mechanism to have the advantages of smooth operation, good continuity; low noise; large bearing capacity; high reliability; compact structure; and small size.
