This joint element is steel ball or bulb stopper.
Bulb stopper can be made up of steel ball and top bolt; Bulb stopper can be made up of steel ball and pad; Also can be that head is a sphere, matrix be the bulb stopper of garden bolt face; Head is that sphere, the field of conjugate action are the conical surface, and matrix is the bulb stopper of garden bolt face.
The contact form of steel ball and fore-set or pad is point, line, surface, and sphere is best.
Driving link, driven member are the driving members with block teeth, and block teeth can be block teeth radially, also can be axial block teeth, i.e. end face block teeth, and the preferably fan-shaped block teeth of block teeth, all the other are neutral gears except that block teeth on the radially or axially garden post of master and slave moving part.Driving link, driven member are formed the time-delay connector; Also can form the time-delay connector by driving link, combination driven member, this driven member is the combination driven member (hereinafter to be referred as driven member) that is connected with axle by driven block teeth cover.
With above-mentioned torque controller and wrench combination, formed new torque spanner.
A kind of wrench for dismounting that is used for thread connection especially can be controlled the spanner of thread connection screwing force, and this spanner is made up of driving end, the arm of force, it is characterized in that: this spanner has the torque controller of being made up of overload device, time-delay connector.
General spanner is made up of the driving end and the arm of force, and the driving end and the arm of force have integrative-structure, and the branch body structure is also arranged.Driving end is the execution part of spanner, and it can block thread connector also can be around the rotating member of the thread connector centre of gyration, and the arm of force is the force application component or the device of spanner.
The torque controller of this spanner has the architectural feature in the technique scheme, can also have:
The driven member of torque controller is designed to and the removable draw bail of driving end, for example ten thousand tenons, spline, hexagonal etc.
The driven member of torque controller can be designed to and the structure of being mated by the thread connector of dismounting, as shapes such as plum blossom hole, hexagon ring, square holes, makes this driven member double as driving end;
The input of the driving link of torque controller connects with the arm of force, for example connections such as thread connection, hinge connection, square tenon, hexagonal, key, pin;
On the surface of revolution of the driven member of torque controller, mark the corner scale
The arm of force of this spanner can be the inertia power set, and this device is by rotating around dead axle and having the rigid body of big rotary inertia and the time-delay connector of torque controller is formed.
Mark the corner scale on the surface of revolution of driving end.
Driving end, torque controller, the arm of force by said structure are combined into following ten kinds of spanners:
Driving end, torque controller, the arm of force are formed torque spanner;
Driving end, torque controller, inertia power set are formed moment of torsion, inertia power operated wrench;
The torque controller of driven member double as driving end and the arm of force are formed torque spanner;
The torque controller of driven member double as driving end and inertia power set are formed moment of torsion, inertia power operated wrench;
The torque controller and driving end, the arm of force that mark the corner scale on the surface of revolution of driven member are formed moment of torsion, are tightened the corner spanner;
Driven member double as driving end and on the surface of revolution, mark the torque controller of corner scale and the arm of force is formed moment of torsion, tightened the corner spanner;
The torque controller and inertia power set, the driving end that mark the corner scale on the surface of revolution of driven member are formed moment of torsion, are tightened corner inertia power operated wrench;
Driven member double as driving end and on the surface of revolution, mark the torque controller of corner scale and the inertia power set are formed moment of torsion, tightened corner inertia power operated wrench;
