Abstract
The utility model discloses an elastic ring connection device for transmission, which belongs to a connection device for transmission arranged between a rotating wheel and a shaft in mechanical transmission. Presently, most of the connection device for transmission adopt a key or an interference fit. Because the connection device for transmission is difficult to mount and dismount, the connection device for transmission is not suitable to be used in equipment which is frequently dismounted. The utility model is composed of a plurality of pairs of an inner and an outer ring. The external surface of the inner ring and the inner surface of the outer ring are provided with conic opening elastic rings and shaft sleeves. The end cover of a shaft is arranged on a rotary shaft. The end cover of the shaft is bolted to realize transmission connection. The elastic ring connection device for transmission has the advantages of simple assembly, convenient dismount and large driving torque. The utility model is suitable to be used in grain processing, mine equipment, etc.
Description
The utility model belongs to transmission joint.
At present being connected between roulette wheel and the rotatingshaft generally adopted key or interference fit, to realize the purpose of transmitting movement, but these Placements are to wheel hole requirement on machining accuracy height, need during assembly and disassembly with wooden mallet or press machine, time-consuming, labor strength is big, and reduces equipment precision, is unsuitable for often adopting on the dismounting equipment.
The purpose of this utility model provides a kind of novel transmission joint, is convenient to installing/dismounting, and saving of work and time alleviates labor strength, uses on the big equipment of frequent dismounting, driving torque being suitable for.
Technical characteristics of the present utility model is, with the axle sleeve of setting-in roulette wheel with some ring outer surface, outer ring inner surface all have the open elastic ring of tapering to be contained on the rotatingshaft in it to being made up of inside and outside ring, and uses bolton behind the ring end in withstanding with hubcap.Outer ring inner surface of its elastic ring and interior ring outer surface are close to, and outer ring outer surface tension shaft cover, interior ring inner surface tightens up rotatingshaft, to realize connecting transmission.
The tapering of the inside and outside ring of elastic ring is between 24 °-34 ° in the utility model, and interior ring tapering and outer shroud tapering differ 1-2 °, are made by spring steel or Bearing Steel.
The utility model has the advantages that and utilize elastic ring, axle sleeve and bolt to replace key to connect or the interference fit connection, simple installation, convenient disassembly.Avoid guaranteeing equipment precision that increase the service life, it is big to be suitable for driving torque, loads and unloads frequent grain processing, uses on the equipment such as mining machinery because hammering damages the phenomenon of machine.
Accompanying drawing 1 is the elastic ring transmission joint figure of flour mill belt pulley.
Accompanying drawing 2 is a ring schematic representation in the elastic ring.
Accompanying drawing 3 is an elastic ring outer shroud schematic representation.
Implementation example: a kind of elastic ring transmission joint that is used for the flour mill belt pulley, assembly relation such as accompanying drawing, its elastic ring 6 is to be made by spring steel, interior ring 9 is that internal diameter is 6.5mm, the outer surface tapering is 29 ° a trip ring, outer shroud 10 is that external diameter is that 9.5mm, internal surface tapering are 28 ° trip ring, be contained on the rotatingshaft 5 after being inlaid in belt pulley 1 on the axle sleeve 8, successively four pairs of elastic rings are inserted on the rotatingshaft 5 then, and add elastic washer 7 at two, three interannulars, ring 9 ends in withstanding with hubcap 4 at last tighten with nut 3.
Claims (3)
1, the transmission joint of a kind of roulette wheel and axle, of the present utility model being characterised in that with the axle sleeve 8 of setting-in roulette wheel 1 and some to forming by inside and outside ring, ring 9 outer surfaces and outer shroud 10 internal surfaces all have the open elastic ring 6 of tapering to be contained on the rotatingshaft 5 in it, and use nut 3 fastening behind ring 9 ends in withstanding with hubcap 4.
2, according to the described transmission joint of claim 1, the tapering of inside and outside ring that it is characterized in that elastic ring is between 24 °～34 °, and the inside and outside ring tapering of every pair of ring differs 1 °～2 °.
3,, it is characterized in that elastic ring is to be made by spring steel or Bearing Steel according to the described transmission joint of claim 1.
