The second projection is arranged so as to prestress a lever spring.
Then a tapered collar (2) is inserted into the inner race, stretching the inner race to prestress the roller elements (15).
The rollers include hollow cylinders defining an interior in which at least one elongated reinforcing member extends to prestress or camber the roller.
However, the torque required to prestress these columns is almost impossible to achieve with conventional bolting methods.
It is proposed that the gear unit (22a; 22b) is provided to prestress the force accumulator unit (18a; 18b) in an unlocking operation and to relieve the stress on the force accumulator unit (18a; 18b) in a locking operation.
Structure is provided for compressively prestressing the rods.
Means for testing and pre-tensioning the accelerometer are also provided.
A spring is provided for biasing the unlock member to a non-activated position.
The force mechanism may prestress the flexure.
A method for pre-loading and fixing a wire rope comprised in the the unifying means is further disclosed.
I have some general policies for filling out ballots:
A tensioning device (18) is additionally provided in order to pretension the piezoelectric element (5) as desired.
The invention relates to a clamping device (1) which is used to clamp a traction mechanism (2) for a traction drive mechanism.
A hydraulic actuator (5) is used to preload the accumulator (4) in a direction reverse to arrow A and an explosive bolt (6) is exploded, thereby releasing the energy of the accumulator (4) as a seismic wave through the geological specimen (2).
According to the invention, a spring element (58) is provided for preloading the retainer piece (38) in the upper position.
The opposite bearing assembly incorporates a spring loaded plunger (60) to pre-load taper roller bearings in both assemblies.
A biasing mechanism (8) is provided for biasing the force transmitting element (4).
The space between the upper (41) and lower (42) decks is occupied by tensioning elements (44) embedded in concrete (45) for prestressing the beam.
To this end, the invention provides a tensioning tool that pre-tensions the tension anchor prior to and during the insertion of the same in the rotor assembly.
In one embodiment, a rolled electroactive polymer device employs a mechanism, such as a spring, that provides a force to prestrain the polymer.
