Abstract
A flywheel structure belongs to the technical field of mechanical transmission parts and adopts the technical scheme that a hub is vertically arranged and fixed at the central part of a friction disc, friction plates are symmetrically riveted and fixed at two side planes of the friction disc close to the excircle, a flywheel is arranged and fixed on the hub through a bearing, a pressure plate is arranged on the side surface of the flywheel at the outer side of the friction disc, hydraulic cylinders are uniformly distributed on the flywheel at the relative side of the pressure plate, pistons are arranged in the hydraulic cylinders, the lower end of a pull rod is connected and fixed with the pistons and the upper end is connected and fixed with the pressure plate through a nut, and the pull rod is sealed with the flywheel through a sealing ring. Therefore, the flywheel structure has torque limit and safe protection function; meanwhile, the space can be effectively saved in the mechanical transmission, and the flywheel structure can be used in smaller spaces.
Description
Technical field
The present invention relates to a kind of structure of flywheel, relate in particular to a kind of structure of overload protection formula flywheel, belong to mechanical transmission component technical field.
Background technique
Flywheel is a kind of power input part in the mechanical transmission, and it generally is installed in the primary side of Transmitted chains, and existing flywheel generally is exactly a rotary component; In mechanical transmission, play the effect of store kinetic energy, in mechanical transmission, sometimes for security needs; The safety protection device of some present moments of torsion need be set, because existing flywheel does not have corresponding limited torque safety protection device, so; In machine driven system, have to safety protection device is arranged on the place of transmission system below elementary; Like this, will cause the overall volume of equipment bigger than normal, be unfavorable for conserve space or use in less space.
Summary of the invention
The objective of the invention is to: the structure that a kind of flywheel is provided; This kind flywheel has the function of torque limiting; In transmission system, need not the limited torque safety protection device to be installed separately in other place; Can reduce the overall volume of equipment effectively, help the conserve space size or use in less space.
The present invention realizes that the technological scheme that above-mentioned purpose adopts is: a kind of structure of flywheel, it by: flywheel, pull bar, pressing plate, friction plate, friction disk, wheel hub, piston, bearing, seal ring, oil hydraulic cylinder are formed, and described friction disk is the structure of disc-shape; Wheel hub vertically is fixed on the center portion of friction disk; At the both sides plane symmetry ground riveted fixing friction plate of friction disk near the cylindrical position, flywheel is fixed on above the wheel hub through Bearing Installation, and the flywheel side in the friction disk outside is equipped with pressing plate; On the flywheel of the relative side of pressing plate, made oil hydraulic cylinder evenly; In oil hydraulic cylinder, be provided with piston, the lower end of pull bar is connected fixing with piston, and the upper end of pull bar is connected and fixed through nut and pressing plate; In the piston cavity of oil hydraulic cylinder, be filled with butter, seal with seal ring between pull bar and the flywheel.
Beneficial effect: the present invention is when work, and when the torque overload on the flywheel, then flywheel is with respect to skidding between the wheel hub; Simultaneously, because this device effectively utilizes the flywheel existing space, need not to arrange separately other bulk; So the present invention not only has the limited torque safety protection function, simultaneously; In mechanical transmission, conserve space is convenient in less place, space use effectively.
