Abstract
The invention discloses an outdoor shaft sleeve pulling and pressing device for excavators and belongs to the field of machinery manufacturing. The outdoor shaft sleeve pulling and pressing device comprises a power assembly (3), a support part (4) and a sleeve part (5). A shaft sleeve (1) is arranged in the shaft hole of a shaft (2). The power assembly (3) comprises a power mechanism (6), a cylinder (7) and a piston rod (8). The power mechanism (6) drives the piston rod (8) to extend out or retract into the cylinder (7). The support part (4) is connected with the cylinder (7), and the sleeve part (5) is connected with the other end of the piston rod (8). A first acting plane (9) acting with the shaft (2) is arranged on the support part (4), while a second acting plane (10) acting with the shaft sleeve (1) is arranged on the sleeve part (5). When the piston rod (8) extends out or retracts into the cylinder (7), the direction of force that the first acting plane (9) applies upon the shaft (2) is opposite to that the second acting plane (10) applies upon the shaft sleeve (1). By the arrangement that the shaft sleeve is pressed out by exerting force upon the cylinder and the piston rod in the opposite direction, greater convenience is brought to outdoor operation, with no need for carrying larger power sources, thus the outdoor shaft sleeve pulling and pressing device can save both time and labor, and damage to the shaft hole is less.
