Abstract
The invention provides an abrasion-resistant coating transmission shaft of a screw drill. The transmission shaft comprises a transmission shaft shell (8), a transmission shaft body (1) is installed in the transmission shaft shell (8) in a penetrating mode, and the transmission shaft body (1) is sequentially provided with an upper movable sleeve (10), an upper static sleeve (9), a serial bearing (7), an anti-falling device and a lower static sleeve (3) from top to bottom. An abrasion-resistant cladding layer (11) is arranged on the contact face of the transmission shaft body (1) and the lower static sleeve (3). According to the abrasion-resistant coating transmission shaft of the screw drill, the abrasion-resistant cladding layer is adopted to replace a lower movable sleeve, the structure of the transmission shaft is simple, the lower movable sleeve is omitted, the effect of reducing cost is reduced, the rough precision of the surface of the abrasion-resistant cladding layer of the transmission shaft is high, friction between the cladding layer and the lower static sleeve is reduced, and abrasion between the cladding layer and the lower static sleeve is reduced. Meanwhile, safety of the transmission shaft is improved, the probability of accidents is lowered, and if abrasion is severe, the transmission shaft can be maintained in the mode that deplating is carried out first and then plating is conducted.
Description
Technical field
The present invention relates to a kind of power transmission shaft, especially relate to a kind of downhole drill screw drill transmission shaft, be applied in oil drilling operation process, the main function realizing raising screw drill transmission shaft security performance and lower radial bearing cover utilization rate.Belong to oil exploitation field of mechanical technique.
Background technology
Helicoid hydraulic motor is the device providing power in recover petroleum natural gas drilling process, comprise by-pass valve assembly, anti-lost assembly, motor assembly, universal drive shaft assembly and driving-shaft assembly, driving-shaft assembly is the on-line equipment passing to drill bit power, and the quality of power transmission shaft will directly affect the application life of bit speed and helicoid hydraulic motor.The driving-shaft assembly of current routine comprises the component (as shown in Figure 1) such as disjunctor water cap, upper dynamic cover, upper quiet cover, string bearing, semi-ring, pressure-bearing cover, lower dynamic cover, lower quiet cover, power transmission shaft and transmission shaft shell.Wherein lower dynamic cover is integrally formed by screw thread and power transmission shaft are fastening, play the effect of spline, but maintenance is not quick detachable after using, lower dynamic cover is all sintered by alloy block to form with lower quiet cover contact surface, during drillng operation, two inner rooms can form sliding friction, bear radial load simultaneously, in the case, lower dynamic cover is more easy to wear, lower dynamic cover can only be changed, cause frequent trips and change lower dynamic cover, cost is higher, cause alloy block cracked time serious, fragment is stuck between two cover gaps, power transmission shaft is caused to rotate, thus damage the equipment such as screw motor and aboveground slush pump.
Summary of the invention
Technical problem to be solved by this invention provides a kind of helicoid hydraulic motor wear-resistant coating power transmission shaft for above-mentioned prior art, it adopts scuff-resistant coating to replace lower dynamic cover, its structure is simple, eliminate lower dynamic cover, reach the effect reducing cost, the scuff-resistant coating rough surface precision of power transmission shaft is high, reduce the frictional force with lower quiet cover, reduce the wearing and tearing with lower quiet inner room, improve the security performance of power transmission shaft simultaneously, reduce accident occur probability, during serious wear, by strip again the mode of plating keep in repair.
The present invention's adopted technical scheme that solves the problem is: a kind of helicoid hydraulic motor wear-resistant coating power transmission shaft, it comprises transmission shaft shell, power transmission shaft is coated with in described transmission shaft shell, described power transmission shaft is disposed with dynamic cover, upper quiet cover, string bearing, falling-proof apparatus and lower quiet cover from top to bottom, described power transmission shaft and lower quiet cover contact surface arrange scuff-resistant coating.
Described falling-proof apparatus comprises bearing ring and semi-ring, and described bearing ring is positioned at above semi-ring, and described bearing ring and semi-ring arranged outside have spacer.
Compared with prior art, the invention has the advantages that:
A kind of helicoid hydraulic motor wear-resistant coating of the present invention power transmission shaft, it adopts scuff-resistant coating to replace lower dynamic cover, and its structure is simple, eliminates lower dynamic cover, reach the effect reducing cost, the scuff-resistant coating rough surface precision of power transmission shaft is high, reduces the frictional force with lower quiet cover, reduces the wearing and tearing with lower quiet inner room, improve the security performance of power transmission shaft simultaneously, reduce accident occur probability, during serious wear, by strip again the mode of plating keep in repair.
