| 摘要 |
The invention is a versatile power rack for transferring power between rotary and reciprocating linear motion comprising a rack assembly (2) with opposed, spaced apart longitudinal portions joined by curved end portions arrayed to form a substantially continuous engaging surface (19); a stator block (7) for guiding the rack assembly in reciprocation linear movement; a pinion wheel (4); a guide cam (1) for holding the pinion wheel (4) continuously in engagement with the engaging surface of the rack (2); and a floating power transfer shaft (3) connected with the pinion wheel (4) and mounted to swing in an arc perpendicular to the linear motion of the rack assembly (2). Linear reciprocation of the rack assembly (2) through the stator block (7) is coupled with rotary motion of the power transfer shaft (8) and periodic rocking of the shaft (8) as the pinion wheel (4) traverses the engaging surface of the rack (2). |
