Abstract

The invention discloses a driving shaft and driven shaft centering device for agricultural machinery. The driving shaft and driven shaft centering device comprises a driving shaft fixing part (5), a driven shaft fixing part (3), a fixed long rod (4), a rotary short rod (6) and a dial indicator (7). When two shafts are centered, the axes of the fixed long rod (4), the rotary short rod (6) and a dial indicator probe (71) and the axis of a driven shaft (1) are positioned on the same plane. When the dial indicator probe (71) slidably contacts with the disk face of a disk (51) with holes, the driven shaft (1) is turned to obtain a measured value of the dial indicator (7), and axial inclination of the two shafts is determined after analysis. When the dial indicator probe (71) slidably contacts with a driving shaft (8), the driven shaft (1) is turned to obtain the measured value of the dial indicator (7), and radial inclination of the two shafts is determined after analysis. The centering device can rapidly check coaxiality of the driving shaft and the driven shaft in power transmission machinery, and is low in cost and high in accuracy.

Description

technical field The invention relates to the technical field of agricultural machinery, in particular to a centering device for calibrating the coaxiality of a driving shaft and a driven shaft in a power transmission system of an agricultural machinery. Background technique In agricultural production, in order to ensure the normal operation of the driven equipment driven by the driving equipment, the centerlines of the driving shaft and the driven shaft should be on the same straight line. When installing the driving equipment and driven equipment, the driving shaft and the driven shaft must be aligned. Find the center. Absolute coaxiality is difficult to achieve. The center deviation of the two shafts mainly includes radial deviation and axial tilt, that is, the two shafts are neither concentric nor parallel. In order to eliminate the deviation, generally after the center line of the driven machine is fixed and leveled , carry out the alignment of the driving shaft and the...
