Handheld hydraulic wrench design
Abstract: Based on the traditional hydraulic wrench developed a new type of drive hydraulic torque wrenches, highlighting driven hydraulic torque wrench works, and through the strength check calculation of the key components to optimize the hydraulic wrench structure it also analyzes its advantages and disadvantages as well as the scope of application, then the whole structure of the hydraulic wrench improved design, which is mainly to improve the design of the rocker and ratchet, ratchet provides a reasonable choice of parameters, which can shorten the product development cycles, improve product reliability, and finally the entire machine operation, maintenance carried out a detailed description, can provide a reference for the selection and use of customers.
Key word： Handheld drive hydraulic torque wrenches; rocker; pawl ratchet.
