Abstract
The utility model relates to an automatic centering and small teeth difference winding drum, wherein, a tooth shape of the utility model can be in an involute shape, a cycloid pin wheel shape or other tooth shapes. The utility model is composed of a small teeth difference speed reducer which is exported by an inner tooth ring, a split type winding drum, an axis coupling for hinges and a pair of bar pin centering supporting seats. The utility model can reduce speed with a large speed ratio, can also greatly automatically compensate position deviation among an axial line of the supporting seat, an axial line of an outside input axial and a winding drum axial lead during manufacture and installation. External dimensions of a machine group can be reduced when the utility model is used in a winch, and dismounting, conveying, and installation are very convenient.
Description
The utility model relates to the roll device that winch is used, the few tooth difference reel of particularly a kind of automatic aligning.
The diameter of existing mine winder reel all very big (more than 1.2 meters), this be for the service life that prolongs steel rope necessary, the deceleration unit all is made up of dead axle garden stud wheel, and places outside the reel.Winch machine shape size is bigger, because underworkings is narrow, digs chamber expense costliness, and therefore, the space that the reel inner chamber is huge does not relatively add utilization, is waste.
Secondly, the spool spindle of existing various lifting winchs is bearing on the bearing by bearing, because antifriction-bearing box does not generally have the aligning function, or the aligning ability is very little, and therefore, must there be higher setting accuracy the position of bearing during installation.
Again secondly, when existing lifting winch unit power imports spool spindle into, transmit by a gear coupling, but the aligning ability of gear coupling is little, to the fair value of the angular deviation between two axial lines only 30 ', therefore, setting accuracy is had relatively high expectations, and gear coupling has strengthened the size of winch in the spool spindle direction at the two between centers certain space that accounts for.
Few tooth difference reel itself has the large speed ratio decelerating power, and the speed reduction gearing gear places in the chamber, therefore, can make the machine shape size reduction, the existing use in ground rigging.
But existing few tooth difference drum diameter is little, so directly use the casing of reel stack shell as reductor, when drum diameter is very big, if still adopt this version, can not separate because of between stack shell and retarder, just can not carry by piecemeal.
Secondly, the eccentric shaft of existing few tooth difference reel directly connects with the exterior power axle, and the no aligning function of eccentric shaft itself.In addition, the bearing pin frame is to be bearing in rigidly on the reel bearing, does not have the aligning function therebetween.Therefore setting accuracy requires very high.
The space is narrow and small in the underworkings, and the cutting of chamber is very expensive, the difficult of large equipment, and the condition of debugging installation is farther not as ground, and winch often needs " change head " construction, replacing place in the down-hole.
The purpose of this utility model is to design a kind of piecemeal carrying of being convenient to, and is convenient to the major diameter reel that whole winch machine packet size is reduced is installed.
The purpose of this utility model is achieved through the following technical solutions:
The few tooth difference reel of a kind of automatic aligning, profile of tooth can be involute, cycloidal-pin wheel or other profile of tooth, the little tooth difference speed reducer that this reel is exported by an internally toothed annulus, a dissection type reel, a hinge coupling and a pair of rod pin aligning bearing constitute, wherein:
The aligning bearing is made up of outer ring, inner ring and cydariform rod pin that half block up and down constitutes, bigger gap is arranged between Internal and external cycle, and be distributed with one group of diameter and the identical post hole, junction of the edges of two sheets of paper garden of cydariform rod pin, and excellent pin of cydariform is inserted in the hole;
The axis body of the bearing pin frame in the little tooth difference speed reducer partly is the pipe of hollow, its two end is fixedly supported upon on the inner ring of aligning bearing, the a pair of casing that is installed in rotation on the bearing pin frame seals the base portion of little tooth difference speed reducer, described base portion comprises internally toothed annulus, satellite gear, eccentric shaft and bearing pin;
Reel is what to separate with the casing of little tooth difference speed reducer, reel is a dissection type, closes outside the casing that is enclosed within little tooth difference speed reducer after disturbing, and the biend of reel is bearing on the bearing pin frame by bearing, little tooth difference speed reducer is connected with reel latch by several, drives reel and rotates;
A hinge coupling is installed in the axis body hollow circular tube partly of bearing pin frame, and the eccentric shaft of one end and little tooth difference speed reducer connects firmly, and the other end is an axle sleeve, and the pullover of axle sleeve stretches out outside the bearing pin frame, can be connected with exterior power source.
The utility model compared with prior art, its advantage is:
1. little tooth difference speed reducer is compared with the cylinder fixed axis gear, and speed ratio is big, and is to be arranged in the reel, therefore, not only makes winch reduce the volume of a cylindrical wheel case, and because of unit can adopt pot motor the machine packet size is further dwindled.
2. reel, retarder, bearing all are piecemeals independently, are convenient to dismounting, carrying, install.And the diameter of reel does not influence the independence of reducer structure.
3. reel and the extraneous part that connects all have automatic aligning function significantly, and it is very convenient to install.
Reel in alternative, the superseded existing various winches of the utility model, the retarder part.Form multiple new winch type.
Below in conjunction with accompanying drawing an embodiment of the present utility model is explained in detail.
Fig. 1 is the longitudinal section of the utility model one embodiment;
Fig. 2 is the cutaway view along the K-K line among Fig. 1.
The little tooth difference speed reducer that the few tooth difference reel of automatic aligning is exported by an internally toothed annulus, a dissection type reel, a hinge coupling and a pair of rod pin aligning bearing constitute.Specifically:
The upper and lower half block 14,12 of bearing constitutes the outer ring of bearing, forms an aligning bearing with inner ring 11 and cydariform rod pin 13.
Bearing pin frame 8 connects firmly with inner ring 11.
Hinge coupling 6 right-hand members and eccentric shaft 9 link, and left end is an axle sleeve 7, and the pullover of axle sleeve 7 stretches out outside bearing pin frame 8.
Reel 5 is dissection types, is bearing on the bearing pin frame 8 by bearing by biend, and 4 of reel 5 and internally toothed annuluss connect transfer torque by latch 2.
Outer power is imported from axle sleeve 7, drives eccentric shafts 9 by hinge coupling 6 and rotates, because bearing pin frame 8 is fixed, therefore, power is exported by internally toothed annulus 4 after large speed ratio slows down through satellite gear 3 and internally toothed annulus 4, and drives reels 5 rotation works by latch 2.
Two of hinge coupling 6 is two universal hinges, can be around any direction deflection.Therefore, axle sleeve 7 floats in bearing pin frame 8 tube chambers, not only can be, but also can radially move around any direction deflection, and also the fair value of displacement is greatly, as long as do not bump with bearing pin frame 8 pipe ends.Therefore, when the spindle nose of exterior power source connects with axle sleeve 7, as long as pack into, needn't centering.It is very convenient when therefore, exterior power source inserts installation.
