A torque multiplier is a tool used to provide a mechanical advantage in applying torque to turn bolts, nuts or other items designed to be actuated by application of torque, such as the actuation of valves, particularly where there are relatively high torque requirements.

Multifunctional calibrating and loading device for torque multiplier

InactiveCN103471768ALarge torque applied load rangeHigh bending and torsional rigidityForce/torque/work measurement apparatus calibration/testingProduction lineMeasurement device
The invention provides a multifunctional calibrating and loading device for a torque multiplier and relates to the testing and calibrating techniques of the torque multiplier. The multifunctional calibrating and loading device is used for solving the problems that a torque loading device is small in measurement range and low in measurement accuracy, has few functions and cannot calibrate torque measurement devices of different structures in the background art. The calibrating and loading device comprises a pure torque loading subsystem, a lifting mechanism subsystem, a screw rod loading subsystem, a non-coaxial multiplier loading-mounting-regulating subsystem and a loading platform system. The multifunctional calibrating and loading device can utilize multiple torque loading manners including a coaxial torque loading manner, a non-coaxial torque loading manner, a double-moment arm torque loading manner or the like and is an important constituent part of a torque multiplier calibrating device; the loading position and manner of the loading device can be regulated according to the size and loading manner of the torque multiplier, and the torque loading problems caused when various torque devices of an assembling production line of an engine are calibrated can be solved by utilizing one set of loading device, so that the practicality of the multifunctional calibrating and loading device is greatly improved, and the cost is saved.

Double-station torque multiplier

ActiveCN103758936ARealize outdoor high torque assemblyImprove securityToothed gearingsSpannersDrive shaftSmall tooth
The invention discloses a double-station torque multiplier. A transmission shaft is provided with a connection gear; one end of a transverse planet carrier is provided with internal teeth, the other end is provided with an eccentric shaft, and a transverse planet gear is sleeved outside the eccentric shaft; the transverse planet gear is meshed with a fixed center gear and an output center gear simultaneously; the fixed center gear is fixed onto a housing through a bolt, and the output center gear is driven by the planet gear to rotate and serves as a torque output shaft. When torque is transmitted to the transmission shaft and the connection gear, the output torque is multiplied after passing an NN type planet gear transmission train of small tooth difference, which is composed of the eccentric planet carrier, the planet gear, the fixed center gear and the output center gear. When the direction of output torque needs to be perpendicular to that of the input torque in assembling work, a rotation screw enables a fork to move the connection gear to be engaged with internal teeth of a bevel gear, transverse torque is changed into perpendicular torque, and the torque is multiplied through the NN type planet gear transmission train of small tooth difference. The double-station torque multiplier is simple in structure and the theoretical torque magnification is high.
