摘要： A shear wrench tool including an electric motor, an output section having first and second output sleeves and a transmission for transferring torque from the motor to the output section wherein in use the output sleeves are caused to be rotated in opposite directions relative to each another, the first output sleeve configured for mating with a nut and the second output sleeve configured for mating with a tip of a bolt to be sheared; the shear wrench tool further comprising an ejection mechanism having a first impact part which is both rotationally and axially movable and which has a first active surface, a second impact part which is rotationally restricted but axially movable and which has a second active surface, the ejection mechanism also having biasing means for urging the first active surface into engagement with the second active surface.

摘要： A sleeve assembly for a shear wrench tool including an output sleeve configured to mate with a nut to facilitate winding of the nut onto a threaded bolt and having a plurality of circumferentially arranged locking features for interlocking with those of a transmission sleeve. A transmission sleeve for transferring torque between the output sleeve and at least one feature of a shear wrench tool transmission section. The transmission sleeve has a first set of circumferentially arranged locking features for interlocking with the locking features of the output sleeve and a second set of circumferentially arranged locking features for cooperating with a locking sleeve. A locking sleeve coupled to the output sleeve in a manner which permits the locking sleeve to rotate between first and second rotational positions relative to the output sleeve.

摘要： A shear wrench tool including an electric motor having a motor output shaft, a transmission having a plurality of planetary gear stages and an output section having first and second output sleeves the first output sleeve being configured for mating with a nut and the second output sleeve being configured for mating with a tip of a bolt to be sheared, wherein the electric motor is configured to provide torque via the transmission to the output section for causing the first and second output sleeves to be rotated in opposite directions relative to each other in use, and wherein the electric motor, the transmission and the output section are arranged in an axial sequence one after the other such that the first and second output sleeves circumferentially extend coaxially around the same axis that the motor output shaft and the planetary gear stages rotate about.
