Abstract
The utility model relates to a special tooling for adjusting bearing clearances of a lifting speed reducer of an ocean platform. The special tooling is characterized by comprising a flange-shaped clearance adjusting gland and a pressing piece, wherein connecting holes are arranged in the clearance adjusting gland, and an internal threaded hole is arranged in the center of the clearance adjusting gland; external threads capable of being in threaded connection with the clearance adjusting gland are arranged on the outer surface of the pressing piece; and a nut used for being connected with a torque wrench is arranged at one end part of the pressing piece. The pressing piece is manually rotated to be clung to an outer ring of a bearing and is then rotated by using the torque wrench to eliminate the axial clearances, and a corresponding bearing gland of a speed reducer shell is manufactured after the axial clearance on each position is calculated, so the precision of the axial clearances of the assembled speed reducer is high, the precision stability is good, the service life of a shaft component of the speed reducer can be prolonged, the maintenance frequency can be reduced, the use cost can be reduced, and the advantages of the special tooling are particularly obvious when the special tooling is applied to the lifting speed reducer of the ocean platform or other places hard to arrive.
Description
Technical field
The utility model relates to a kind of ocean platform lifting with decelerator manufacturing frock, particularly a kind of ocean platform lifting decelerator bearing gap adjustment special tooling.
Background technology
Ocean platform provides the structures of production and living facilities for carrying out the activities such as drilling well, oil recovery, transporting something containerized, observation, navigation, construction at sea.Marine drilling platform is comprised of three whole spud legs, formed by three groups of gear rack lifting systems on each spud leg, the lifting decelerator that adopts speed ratio can reach 8000 or more provides high pulling torque to export, the lifting of the engagement process implementation platform by climbing gear and tooth bar.The lifting decelerator is the assurance of the high stationarity of lifting platform system super large load.The lifting decelerator adopts 5 planetary gears and high-precision gear (ISO4-5 level) to realize that load all carries transmission, make the lowering or hoisting gear profile more compact and reasonable, from heavy and light, reach design abroad and manufacture level.According to the projected life of customer requirements, by proportioning and the equivalent lifetime principle of furtheing investigate gears at different levels, carry out the loading spectrum analysis, under the prerequisite that guarantees safety coefficient, greatly sleeve mechanism is carried out loss of weight and optimization, adapted to ocean platform to the requirement of jacking system reduction box from heavy and light.
The ocean platform lifting belongs to parallel decelerator with decelerator, and the block bearing of its power transmission shaft all uses in pairs.This kind structure is when assembling, and end play is difficult to control, and end play precision control stability is poor, on causing very large impact the service life of decelerator.And because the restriction of its place to use, when this decelerator was keeped in repair, cost was very high.
Summary of the invention
The ocean platform lifting that the technical problems to be solved in the utility model provides a kind ofly can improve the end play precision stability, improve service life is with decelerator bearing gap adjustment special tooling.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of ocean platform lifting decelerator bearing gap adjustment special tooling, its innovative point is to comprise: gland is adjusted in a flange-like gap, described gap is adjusted on the gland and is had connecting hole, and the gap is adjusted the gland center and opened internal thread hole; One compressing member, the setting of described compressing member outer surface can be adjusted the external screw thread that gland is threaded with the gap, and a described compressing member wherein end is provided for the nut that is connected with torque spanner.
Further, described compressing member is an axle sleeve structure, and an end of described axle sleeve connects a keyboard, connects the nut that is connected with torque spanner on the keyboard.
The utility model has the advantage of: utilize the manual rotation compressing member to be close to bearing outer ring, rotatably compress part by torque spanner again and eliminate end play, and make afterwards as calculated the bearing gland of corresponding reducing gearbox according to each locational end play, so that the reducer shaft after the assembling is high to gap precision, precision stability is good, but the service life of prolonged deceleration device shaft assembly, reduce frequency of maintenance, reduce use cost, particularly be applied to ocean platform lifting decelerator and other places that is difficult to arrive are particularly evident.Adopt a keyboard to realize the installation of nut on axle sleeve, simple in structure, and make things convenient for the measurement of size.

The specific embodiment
As shown in Figure 1, 2, it comprises: gland 5 is adjusted in a flange-like gap, and the gap is adjusted on the gland 5 and had connecting hole, and the gap is adjusted gland 5 centers and opened internal thread hole; One compressing member 6, these compressing member 6 outer surface settings can be adjusted the external screw thread that gland 5 is threaded with the gap, and compressing member 6 a wherein end is provided for the nut that is connected with torque spanner.The compressing member 6 that adopts in the utility model is hollow shaft sleeve shape structure, and its internal diameter is slightly less than the outer ring external diameter of bearing B2 greater than the inner ring external diameter of bearing B2, and an end of hollow shaft sleeve connects the nut 7 of torque spanner front end sleeve by a keyboard 8.This nut 7 also can be other connectors with outer regular polygon structure or internal regular polygon structure.
During use, concrete steps are as follows:
A) shown in Fig. 3,4, at first with reducer shaft 3 two ends connection bearing A1 and bearing B2, bearing A1, bearing B2 are installed in the bearing mounting hole of reducing gearbox 4 two sides.Wherein the bearing A1 of an end is spacing by step surface or other structures of reducing gearbox 4 bearing mounting holes, and the bearing B2 of the other end does not carry out spacing.
Gland 5 is adjusted in the gap of b) then special tooling being installed outside the bearing mounting hole of bearing B2, and this gap is adjusted gland 5 and is bolted with these side speed reducer shell 4 lateral walls.
C) adjust the compressing member 6 that gland 5 internal threads connect special tooling in the gap, the end that compressing member 6 does not arrange nut 7 stretches in the bearing mounting hole in the step b) and over against the outer ring of bearing B2.
D) by manual rotation compressing member 6, so that the end of compressing member 6 just contacts with the cycle surface of bearing B2.
E) rotatably compress part 6 by torque spanner, and after reaching fixing moment of torsion, stop, moving forward a segment distance to eliminate end play so that the end of compressing member 6 props up bearing B2 cycle surface.
F) measure compressing member 6 and stretch out the distance L that gland 5 outer faces are adjusted in the gap, calculate the degree of depth C that compressing member 6 stretches into reducing gearbox 4, C=B-A-L according to the thickness A of gap adjustment gland 5 and the length B of compressing member 6.During measuring distance L, adopt three point measurement methods in this step, adjust gland 5 in the gap and choose approximate equally distributed three point measurements with the contact position of compressing member 6, to improve measurement accuracy.
G) make at last and assemble the bearing gland of reducing gearbox 4, the bearing gland boss thickness C of this reducing gearbox 4 '=compressing member stretches into the gap size of the degree of depth C-designing requirement of reducing gearbox, so that after bearing gland loads onto, the boss of bearing gland props up bearing B2 outer ring, realizes the installation of bearing B2.
