Embodiment Construction

[0008] as attached figure 1 As shown, the planetary gear train of the present invention is formed by the sun gear 1 , the planetary gear 2 , the sun gear 3 and the member 4 . One of the hydraulic motors 6 meshes with the center wheel 1 through one of the gears 5; the other hydraulic motor 6 meshes with the sun gear 3 through the other gear 5, so the power of the two hydraulic motors 6 is respectively The input is on the center wheel 1 and the sun wheel 3, and the flows of the two hydraulic motors 6 are respectively controlled by the two proportional speed regulating valves 7, which forms the power input system of the present invention. In order to balance the centrifugal inertial force generated by the planetary gears and reduce the force of the planetary gears, six planetary gears 2 are symmetrically distributed between the center gear 1 and the sun gear 3 . Each end of the six connecting shafts 7 is respectively fixed to the central shafts of the six planetary wheels 2; eac...

Abstract

The invention relates to a novel oil pipe screwing machine, which is an electric tool for screwing or removing a screw connection device, and belongs to the field of machinery manufacturing. It uses hydraulic dual motors to drive the planetary gear transmission mechanism to realize the adjustable and controllable speed, and uses the differential speed to realize the stepless speed change of the speed. It is characterized in that the planetary gear system is composed of a central gear, a planetary gear, a sun gear, and components, and the central gear, planetary gear, and sun gear are arranged in sequence from the inside to the outside, and the inner teeth of the sun gear and the outer teeth of the sun gear are respectively connected with the outer teeth of the planetary gear. The teeth mesh. The center wheel and the sun wheel are respectively connected with corresponding hydraulic motors through gears. One end of the main tong is connected to the planetary gear shaft through the connecting piece, and the other end is fixed to the single-rod oil cylinder. The invention has the advantages of large speed ratio, large torque, no shock, no noise, no equipment damage, simple operation and the like.

Description

technical field [0001] The invention relates to a novel oil pipe screwing machine, which is an electric tool for screwing or removing a screw connection device, and belongs to the field of machinery manufacturing. Background technique [0002] At present, the driving force of the oil pipe wrench and screwing machine electric tools used on the market are realized by hydraulic motors through gear shifting and speed change. The working characteristics of make-up and breakout are: the torque is small and the speed is high when the make-up is pre-tightened; after the make-up, the torque gradually increases and the speed gradually decreases. Thereby existing oil pipe tongs, its speed change mode of twisting machine exist: the defects such as shifting out, having noise, easy damage of equipment, difficult operation. Therefore changing the rotary speed change mode of existing tubing tongs and screwing machines to make up for the defects caused is the primary issue to be solved urge...
