Abstract
The utility model discloses a motor assembly apparatus for screw rod drill, belonging to the technical field of the drilling tools. The motor assembly apparatus for a screw rod drill comprises a stator (1) provided with a tubular shell and a multi-lobe spiral rubber inner cavity, a spiral hollow shaft shaped rotor (2) sheathed in the stator (1), a flexible shaft (3) which passes through the hollow rotor (2) and is connected with a transmission shaft. The motor assembly apparatus for the screw rod drill can convert the planetary motion of the rotor (2) into the fixed shaft motion of the transmission shaft, and therefore, the integral length of the drill is shortened and the service life is improved. The utility model is a new-type well construction tool.
Description
The utility model belongs to the drilling tool technical field.
That helicoid hydraulic motor of enlightening of introducing from the U.S. mainly is to be made of by-pass valve assembly, motor assembly, universal drive shaft assembly, driving-shaft assembly four parts at present, wherein motor assembly comprises stator and rotor two parts, the shell of stator is a tubulose, the interior rubber of annotating, its shape of cross section is a helicla flute, rotor is a spiral oblique crank Z, and along the whole length of motor assembly, stator and epitrochanterian respective point form one and continue sealing; The universal drive shaft assembly comprises tubulose universal drive shaft housing, the suit two ends have the lobe profile of tooth universal drive shaft of good characteristics of flexibility respectively in the universal drive shaft housing, the lobe tooth surface is with the rubber sleeve of oil resistant, fill with the butter of lubricate in the rubber sleeve, universal drive shaft assembly upper end is connected with the water conservancy diversion water cap of screwed connection its lower end in motor assembly lower end with the power transmission shaft upper end.The motor assembly of this structure and universal drive shaft assembly; its shortcoming mainly shows: at first connect the conversion of finishing motion and the transmission of power with lobe profile of tooth universal drive shaft between rotor and the power transmission shaft; because this outer lobe tooth universal drive shaft structure that connects; the entire length of drilling tool has extended; secondly, the universal drive shaft surface is protected with rubber sheath, comes off easily under the high-pressure slurry erosion; the plugging fluid circulation road has only 80～120 hours application life.
The purpose of this utility model is to design a kind of new screw drilling tool motor assembly device that motor assembly and universal drive shaft assembly " are united two into one ".
The utility model comprises: annotating the rubber shape of cross section in the tubular outer shell is spiral fluted stator and helical axis shape rotor two parts, its improvements are: rotor is made hollow, and thin and long flexible axle passes sleeve rotor and constitutes its upper end and its lower end of screwed connection, rotor upper end and be connected with water conservancy diversion water cap on the power transmission shaft.
The utility model has shortened the entire length of drilling tool greatly owing to adopted flexible axle to pass the sleeve rotor structure, simultaneously the application life that replaces universal drive shaft to improve drilling tool with flexible axle.
Embodiment of the present utility model provides in conjunction with the accompanying drawings.
Fig. 2 is a screw drilling tool motor assembly apparatus sectional view.
In the present embodiment, stator (1) shell is a steel pipe, stator (1) inside is six lobe helical cavity of the vulcanization of rubber, rotor (2) is a steel five lobe spiral hollow shafts, five lobe spirality sleeve rotors (2) are sleeved in the stator (1) of six lobe helical cavity, make rotor (2) in stator (1), form many continuous not connected annular seal spaces, allow thin and long flexible axle (3) pass through sleeve rotor (2) then, make the upper end screwed connection of flexible axle (3) upper end and sleeve rotor (2), flexible axle (3) lower end is connected with the water conservancy diversion water cap of power transmission shaft upper end.
Claims (2)
1, a kind of screw drilling tool motor assembly apparatus, it comprises that annotating the rubber cross section in the tubular outer shell is spiral fluted stator (1) and helical axis shape rotor (2) two parts, it is characterized in that rotor (2) makes hollowly, thin and long flexible axle (3) passes sleeve rotor (2) and constitutes its upper end and its lower end of screwed connection, rotor (2) upper end and be connected with water conservancy diversion water cap on the power transmission shaft.
2, screw drilling tool motor assembly apparatus according to claim 1 is characterized in that five lobe spirality sleeve rotors (2) are sleeved in the stator (1) of six lobe helical cavity.
