Abstract
The utility model belongs to a clutch or a gear device. The utility model has the design scheme that a transmission shaft is arranged in a connecting sleeve in a movable fit mode, and the connecting sleeve is connected with a casing of a gear box into a whole; a ratchet wheel sleeve which is assembled with a ratchet wheel into a whole is sheathed on the connecting sleeve in a clearance fit mode; an annular contracting brake in a clamping type is arranged at an outer ring of the ratchet wheel sleeve; a lower lug of the contracting brake is fixedly connected with a bracket arranged on the casing of the gear box by bolts; an upper lug of the contracting brake is provided with a braking bolt; the ratchet wheel and the transmission shaft are locked by a flat key, and the symmetrical positions of the shaft center of the side surface of the ratchet wheel are provided with clutch ratchet pawls which can rotate with the ratchet wheel in a one-way mode. The utility model has the advantages that the reverse rotation of a mechanical system, which is caused by the accumulated reverse spring force of a mechanical transmission system is overcome, and the reverse spring force can be slowly released under the manual control; thus, the utility model assures that the operation of the mechanical system is safe, and a human body is not injured.
Description
Technical field
The utility model belongs to clutch or gearing, particularly a kind of releasable super-clutch type anti-reverse mechanism.
Background technique
Mechanical rotary device, when stopping to drive, the mechanical energy of system's savings will discharge, and normally converse output energy orders about the mechanical device counterrotating, and this phenomenon is harmful to often.In the oil recovery operation process, the pump rod post of the transmission power that it is elongated (the about 30mm of diameter, length is about 1000mm) has been put aside higher reverse elasticity energy as oil pumping screw pump.When driving stopped, this huge reverse elasticity energy was released, and ordered about drive unit high-speed reverse rotation, very easily caused the damage of transmission device or human injury took place or pump rod screw thread back-off is got loose, and crashed into the down-hole, produced the oil well accident and stopped production.
Summary of the invention
For solving the deficiencies in the prior art, the utility model has designed a kind of releasable super-clutch type anti-reverse mechanism.Its design proposal is: in the connecting sleeve that fuses with gear box casing, transmission shaft has been installed movingly.Being set on the connecting sleeve with ratchet all-in-one-piece ratchet sleeve Spielpassung.At the outer shroud of ratchet sleeve annular snap compact form band-type brake has been installed.The following ear of band-type brake and the support on the gear box casing are connected and fixed with bolt.The last ear of band-type brake is equipped with the brake bolt.Pawl wheel and transmission shaft lock with flat key.The axle center, side of pawl wheel symmetrical position installed can with the clutch ratchet of ratchet one-way rotation.
The anti-reverse mechanism of above-mentioned design, pawl wheel can be under the drives that moving transmission shaft is rotated in the forward, and make to be installed on this ratchet of taking turns and to open under action of centrifugal force, break away from the engagement with ratchet, and realizing that forward is moving changes.When the forward running stops, reverse elasticity power from the pump rod post, to order about the pawl wheel counterrotating by transmission shaft, because ratchet is fixed by band-type brake, the ratchet that is installed on the pawl wheel has been stuck on the tooth of ratchet in contraction under the effect of spring force, make clutch ratchet and ratchet one-way locking on the pawl wheel, can not counterrotating.When needs release comes from the reverse elasticity power of elongated pump rod post, only need the brake bolt of ear on the band-type brake is unclamped gradually, the band-type brake un-brake, ratchet will lose fixing and counteresteer effect, and stinging ratchet wheel can counterrotating.Make the reverse of pawl wheel that can be by transmission shaft from the reverse elasticity of pump rod post be able to slow release.
The advantage of this anti-reverse mechanism is: both can overcome machine driven system because the reverse elasticity power of savings causes the counterrotating of mechanical system; the slow release of reverse elasticity power under artificial control can be guaranteed that the mechanical system safe operation and the person are without prejudice again.
