With the increasing of petroleum exploration and development dynamics, the probing workload of the Holes of Complicated Wells such as deep-well, ultradeep well shows year by year
The trend of rising.But problems are encountered during deep-well, ultra-deep well drilling, deep-well, ultra-deep well drilling will drill
More set stratum, the stratum for boring chance is ancient, fine and close, abrasiveness is strong, hardness is high, and bit speed is slow；Prolonged construction is easy to make
Drilling tool is caused to be seriously worn or be damaged, to cause accident, is needed new drilling technology to improve bit speed, is shortened drilling well week
Phase improves exploration and development benefit.
In oil drilling, drilling tool fractured rock is driven, is crept into underground, the wellbore of prescribed depth is drilled out, for oil production machine
Or gas production machine obtains petroleum or natural gas.One common oil-well rig is mainly by engine, driver, working machine and ancillary equipment
Deng eight most of compositions.There are two types of oil-well rig top-drive drilling load structures, one of the most common type structure
For the carrying of main shaft single channel, in drilling well and the processes such as make a trip, all load are acted on main shaft, and pass through base bearing biography
It is delivered on cabinet, so base bearing should play the role of rotation, transmitting torque is played again, since drill bit is in ground end
In drilling process, the different situations of geology will lead to bit force mutation, and lead to the rotation system even damage of engine.
Utility model content
The main purpose of the utility model is to be transmitted on cabinet for the main shaft load of solution oil drilling by base bearing,
Load moment is larger and the problem of changing greatly, and proposes one kind and drives reduction gearbox more, can install multiple driving machines, and dispersion passes
Torque is passed, single driving machine Moment is reduced.
The utility model is in order to solve the above technical problems, used technical solution is: a kind of more drivings of oil-well rig
Reduction gearbox, including the inner ring connecting with drill bit, inner ring outer peripheral surface is provided with the shaft shoulder on middle part, and the shaft shoulder respectively installs an axis up and down
It holds, passes through gear connecting plate connection bull gear outside the shaft shoulder, be provided with outer ring outside bearing, be provided on outer ring multiple dynamic for installing
The flange of power machine, outer ring both ends are respectively arranged with upper end cover and lower cover.
Further, outer ring includes upper outer ring and lower outer ring, and the two is bolted.
Further, upper end cover and lower cover are towards being provided with sealing device at inner ring.
Further, sealing device includes the groove being opened on upper end cover and lower cover inner peripheral surface, slot opening outwardly,
Felt seal and O-ring are provided in groove, being provided with end cover outside groove prevents O-ring from dropping out.
Further, bearing is installed back-to-back using two tapered roller bearings.
Further, gear connecting plate is made of upper and lower two annulus, and lightening hole is provided on annulus.
The utility model has the technical effect that
The reduction gearbox of the utility model connects cabinet and main shaft using dual bearing structure, while guaranteeing main shaft rotation, energy
It enough undertakes axial force and power of toppling, securely and reliably, while one bull gear is set in inner ring, multiple engine drivings are arranged in outer ring
Main shaft rotation, play certain decelerating effect, compact-sized, the setting of more engines can disperse stress, substantially increase by
Power uniformity is to extend in the reduction gearbox service life, improves the reliability and safety coefficient of drilling equipment, have preferable promotion price
Value.

Specific embodiment
Further specific detailed description is done to the utility model with reference to the accompanying drawings and detailed description.
As depicted in figs. 1 and 2, the more driving reduction gearboxes of a kind of oil-well rig, including the inner ring 1 being connect with drill bit, inner ring 1
The shaft shoulder is provided in the middle part of outer peripheral surface, the shaft shoulder respectively installs a bearing 2 up and down, passes through gear connecting plate 3 outside the shaft shoulder and connects canine tooth
Circle 4, bearing 2 are provided with outer ring 5 outside, multiple flanges 9 for being used to install engine are provided on outer ring 5,5 both ends of outer ring are set respectively
It is equipped with upper end cover 6 and lower cover 7, the engine installed on flange 9 drives pinion gear to drive large ring gear 4 rotations, to drive master
Axis rotation, while realizing deceleration.
Further, outer ring 5 includes upper outer ring 501 and lower outer ring 502, and the two is bolted, and it is upper and lower that outer ring 5, which is divided,
Two parts are simultaneously detachably installed by bolt, and outer ring 5 is facilitated to install.
Further, upper end cover 6 and lower cover 7 towards be provided at inner ring 1 sealing device 8 prevent the grease of bearing 2 to
