Technical problems of relatively inconvenient assembling and disassembling, complex operation, incapable reusing, and likely damaged cooperative surface as well as poor machining precision and need of reaching higher precision in a cooperation of workpieces in the reducer in the prior art, caused by that a reducer output shaft is required to be connected with a mechanical shaft by a bond, are solved mainly. The telescoping type reducer comprises a reducer; a reducer output shaft is arranged in the reducer; a mechanical shaft is inserted into the reducer output shaft in a penetrating manner; a shrink disc mechanism capable of tightly holding the mechanical shaft by the reducer output shaft is sleeved out of one end of the reducer output shaft; a locating straight sleeve is arranged in one end of the reducer output shaft, while an output shaft conical surface is arranged in the other end of the reducer output shaft; a conical sleeve is expanded in the conical surface; and the locating straight sleeve and the conical sleeve are respectively arranged on both ends of the mechanical shaft.

Description

A kind of set type retarder with shrink disk
Technical field
The utility model relates to a kind of retarder, especially relates to a kind of set type retarder with shrink disk.
Background technique
At present, the gear reduction unit of being used widely, worm-gear speed reducer, be subject to volume restrictions, its speed ratio is less than normal, and its transmission direction is generally parallel input output and can not satisfies some existing large speed ratios mini-plant that has again the vertical-transmission direction to require that slows down and install and use.Chinese patent discloses a kind of double worm gear reducing mechanism (notice of authorization number: CN 201250880Y), it comprises worm type of reduction gearing, be provided with two worm type of reduction gearings, worm screw on two worm type of reduction gearings links together by the adjustable coupling of axial rotation angle, realizes synchronization; Have at least one worm screw two ends all to stretch out in himself reducer shell in two worm type of reduction gearings, with a end that coupling is not installed on this worm screw input shaft as this reducing gear; Output shaft on each worm type of reduction gearing is connected with respectively a small gear; Small gear simultaneously and the gearwheel engagement driving, and with the transmission shaft at the gearwheel place output shaft as this reducing gear; The two ends of the worm screw of two worm type of reduction gearings all stretch out in the separately housing of retarder itself, two worm type of reduction gearings and connected small gear respectively, has respectively identical specification, the coupling that employed axial rotation angle is adjustable is made of two half-couplings, some screws evenly distribute on one of them half-coupling, corresponding described screw is provided with the slotted hole of some arcs on another half-coupling, is fastenedly connected by screw between two half-couplings.But this retarder need to link together reducer output shaft and mechanical axis by key, and mounting or dismounting are inconvenient, complicated operation, not reproducible use, and the surface of cooperation is easily damaged, and machining accuracy is relatively poor, and workpiece need to reach higher precision when cooperating.
The model utility content
The utility model provides a kind of set type retarder with shrink disk, it mainly is to solve the existing retarder of prior art need to reducer output shaft and mechanical axis be linked together by key, mounting or dismounting are inconvenient, complicated operation, not reproducible use, the surface that cooperates is easily damaged, and machining accuracy is relatively poor, need to reach the technical problem of higher precision etc. when workpiece cooperates.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
A kind of set type retarder with shrink disk of the present utility model, comprise retarder, be provided with reducer output shaft in the described retarder, the inner cross-under of reducer output shaft has mechanical axis, one end outer cover of reducer output shaft is connected to the shrink disk mechanism that reducer output shaft can be held tightly mechanical axis, one end inside of reducer output shaft is provided with the positioning straight cover, reducer output shaft the other end inside is provided with the output shaft conical surface, expanded joint has tapered sleeve in the conical surface, and positioning straight cover, tapered sleeve are located at respectively the two ends of mechanical axis.Shrink disk is housed on the reducer output shaft, regulate shrink disk, produce and radially hold expansive force tightly, hold the output shaft outer shroud tightly and make the output shaft contact area produce distortion, the aperture dwindles and holds mechanical axis tightly, along with the increase of shrink disk expansive force, the corresponding increase of the enclasping force of output shaft and mechanical axis, with reach transmit required torque, axial force or the combined load of the two till.And by the positioning straight cover location with tapered sleeve, mechanical axis is positioned in the reducer output shaft, so that the assembly precision of each workpiece need not is too high.
As preferably, described shrink disk mechanism comprises and is socketed in shrink disk disk body on the reducer output shaft, the outer surface of shrink disk disk body is provided with symmetrically arranged two sections shrink disk conical surfaces, is glued with respectively two adjustment disks on two sections shrink disk conical surfaces, links together by adjusting bolt between the adjustment disk.By adjusting bolt, can be so that two adjustment disks be close, thus by conical surface extruding locking plate disk body, make and press locking plate disk body aperture to dwindle.
As preferably, described tapered sleeve is provided with locking ring outward, and locking ring is provided with lock bolt.By lock bolt, tapered sleeve can be pressed in the reducer output shaft.
Therefore, the moment of torsion of the utility model transmission is large, precision is high, mounting or dismounting are convenient and swift, simple to operate, polarization is good, reduce the processing grade be output axle and mechanical axis, reusable, do not damage matching surface, and the assembly precision of each workpiece when assembling need not too high, simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 2 is side structure schematic diagram of the utility model tapered sleeve, locking ring.
Component, position and numbering among the figure: retarder 1, reducer output shaft 2, mechanical axis 3, positioning straight cover 4, the output shaft conical surface 5, tapered sleeve 6, shrink disk disk body 7, the shrink disk conical surface 8, adjustment disk 9, adjusting bolt 10, locking ring 11, lock bolt 12.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: a kind of set type retarder with shrink disk of this example, such as Fig. 1, Fig. 2, a retarder 1 is arranged, it is characterized in that being provided with in the described retarder reducer output shaft 2, the inner cross-under of reducer output shaft has mechanical axis 3, one end outer cover of reducer output shaft is connected to the shrink disk mechanism that reducer output shaft can be held tightly mechanical axis, shrink disk mechanism comprises and is socketed in shrink disk disk body 7 on the reducer output shaft, the outer surface of shrink disk disk body is provided with symmetrically arranged two sections shrink disk conical surfaces 8, be glued with respectively two adjustment disks 9 on two sections shrink disk conical surfaces, link together by adjusting bolt 10 between the adjustment disk.One end inside of reducer output shaft is provided with positioning straight cover 4, and reducer output shaft the other end inside is provided with the output shaft conical surface 5, and expanded joint has tapered sleeve 6 in the conical surface, and tapered sleeve is provided with locking ring 11 outward, and locking ring is provided with lock bolt 12.Positioning straight cover, tapered sleeve are located at respectively the two ends of mechanical axis.
