2. double end mechanical type impact wrench (centre-to-centre spacing is non-adjustable).
The spanner of this structure provides power by gasoline engine, is also to bolt collar output torque by mechanical shock mode.The power of engine drives respectively two impact type sleeves by two output shafts of mechanical type transfer gear box, can the fastening bolt of the rail left and right sides be screwed or be loosened simultaneously, and than single head mechanical type impact wrench, operating efficiency is higher.But still there is obvious deficiency in the spanner of this structure: (1) operator cannot preset the operation torque of sleeve; (2) bolt screw moment of torsion can only lean on sleeve number of shocks come rough control torque; (3) centre-to-centre spacing of left and right impingement sleeve is fixed, and can only be applicable to the fastening operation of a certain type, and for adapting to the deviation of fastening bolt centre-to-centre spacing, can only adopt " universal joint " formula bolt collar, has reduced the accuracy that screws moment of torsion.
3. single-head hydraulic formula torque wrench.
The spanner of this structure provides power by gasoline engine, carries out static(al) screw or loosen with fluid motor-driven bolt collar contacting piece bolt; The operation torque of motor depends on the pressure of hydraulic system, and system pressure is by pressure valve control, and the pressure of motor and the relation of moment of torsion rely on conversion pressure to obtain.The desired value of sleeve moment of torsion obtains by the controlled pressure of adjusting pressure valve.But also there is obvious deficiency in the spanner of this structure: the operation torque poor stability of (1) sleeve, and the height of oil temperature in hydraulic system directly affects the opening feature of pressure-control valve, causes the operating pressure of motor that obviously fluctuation occurs; (2) fastening bolt of the rail left and right sides can only screw successively, causes rail both sides to be subject to offset loading force;
4, double end fluid pressure type torque wrench (centre-to-centre spacing is non-adjustable).
The spanner of this structure provides power power by gasoline engine, and the driving force of hydraulic motor drives respectively two sleeves by two output shafts of transfer gear box, can carry out static(al) to the fastening bolt of the rail left and right sides respectively and screws or loosen.Except with the shortcoming of same existence of single-head hydraulic formula torque wrench " operation torque poor stability ", also have the following disadvantages: (1) two sleeve can only synchronous rotary, cannot make the fastening bolt of the left and right sides reach same torque value simultaneously, be commonly called as " false double end "; (2) centre-to-centre spacing of left and right sleeve is fixed, and can only be applicable to the fastening operation of a certain type, otherwise needs transverse moving left and right equipment to make sleeve aim at bolt, can cause the impact damage of road wheel.
