A rubber element adopted in the utility model serves as a shock-absorbing element, so as to improve the use stability of the shock absorber. The rubber shock absorber can effectively overcome the defects of the conventional shock absorber, and improves the service life of the shock absorber.
Description
Technical field
The utility model relates to a kind of rubber absorbers, belongs to the drilling technology field.
Background technology
In drilling process, the vibration of drill bit and drill string and impact dynamic load are very big to the equipment influence on ground, have a strong impact on the application life of ground installation.In order to slow down drill bit and drillstring vibrations and to impact the influence of dynamic load to ground installation, usually the compressive strain of employing damper absorbs the vibrational energy of drill bit and drill string, keep stablizing the pressure of the drill and moment of torsion to reach, reduce the flutter failure of drill bit, drilling tool and ground installation, improve the purpose of rate of penetration and reduction drilling cost.Existing damper has hydra-shock absorber and mechanical damper, and they all have the hydraulic oil part, and the sealing and the temperature of product all proposed higher requirement.
Summary of the invention
The purpose of this utility model is, a kind of rubber absorbers are provided.Adopt rubber tube as main damping element, can reduce the machining accuracy of damper component, and have the good result of slowing down drill string vibration and impacting dynamic load, improve the product job stability.
The technical solution of the utility model: a kind of rubber absorbers, formation comprises splined mandrel, and splined mandrel is threaded with axle, and the axle end is provided with piston; Splined mandrel is with outward mends core retainer plate tube and spline urceolus, and the axle overcoat is had the inclination neck bush, is with rubber tube on the axle lining, and rubber tube is provided with the damping urceolus outward, and damping urceolus one end is threaded with the spline urceolus, and the damping urceolus other end is threaded with lower contact.
In the aforesaid rubber absorbers, described rubber tube is made of more than one rubber ring.
In the aforesaid rubber absorbers, described piston is threaded with axle, fixes through lock-screw.
In the aforesaid rubber absorbers, describedly between splined mandrel and spline urceolus, be provided with dummy piston.
In the aforesaid rubber absorbers, it is stifled that the spline urceolus at described dummy piston place is provided with oil.
In the aforesaid rubber absorbers, described rubber tube two ends are provided with guide ring and buffering ring.
In the aforesaid rubber absorbers, it is stifled that the damping urceolus at described piston place is provided with oil.
Compared with prior art, hydra-shock absorber of the prior art, hydraulic oil is higher to the sealing requirements of product, and is also higher to the machining accuracy of part.And temperature is also big to the stability influence that product uses; Mechanical damper of the prior art mainly relies on spring element and hydraulic oil damping, because service time is long, load is big, and spring element was lost efficacy.The utility model adopts rubber element as damper element, has improved the stability that damper uses.Can effectively overcome the deficiency of existing damper, improve the application life of damper.
