Description

Clip built-in type axle envelope driving component structure

Technical field

The utility model is relevant for a kind of clip built-in type axle envelope driving component structure, especially the shaft seal structure that uses in a kind of rotary machine that is applicable to pumping and so on, the module that it can be assembled into a clip in advance, fast simple when making installation, and comparatively simple structure is arranged.

Background technique

The shaft seal structure that uses in the rotary machine of tradition pumping and so on, it needs the installation personnel by the tool rich experiences, each member is enclosed in one by one in the space of the axis hole of rotary machine and rotatingshaft, and after installing, find to have the seepage situation, after those members need being retrieved its gap of adjustment again, again this member is packed into one by one, because the space of the axis hole of this rotary machine and rotatingshaft is limited, so comparatively difficulty and inconvenience of this installment work.

Application has TaiWan, China to announce " the clamping type gland seal device of rotary machine " patent case No. 459938 before the applicant, it mainly is the axle 71 that is sheathed on rotary machine 70 by axle sleeve 10, be movably set in axle sleeve end cap 11 side edge on the axle sleeve 10 with one first change group 20, be movably set in the place, axis hole 72 ends of rotary machine relative on the axle sleeve 10 70 with one first axle collar 30, be fixedly arranged on rotary machine 70 side butts with an enclosing cover 40 and fix first axle collar 30, be installed on axle sleeve 10 foreign ministers to enclosing cover 40 containing grooves 43 inside with the second change group 50, the end that is installed in axle sleeve 10 axle sleeve end caps 11 far away with second axle collar 60 is located, and with respect to enclosing cover 40 outsides.

Before though this patent case can be applied to rotary machine with this gland seal device, assemble in advance to join in advance and carry out the leakproof test, after guaranteeing that this gland seal device does not in use have the problem that cooling circulation liquid leaks outside, actual device is used on rotary machine again, to avoid gland seal device to be fixed on the rotary machine, the puzzlement of dismounting again if the generation circulating liquid leaks outside.But it is complicated that this gland seal device still shows, and cost is also higher relatively.

Summary of the invention

The utility model main purpose is to improve above-mentioned shortcoming, and so that a kind of clip built-in type axle envelope driving component structure to be provided, it has comparatively simple structure, make this gland seal device be easy to assembling, and cost can reduce.

Clip built-in type axle envelope driving component structure of the present utility model is to establish other end of several positioning holes by sleeve one end to establish ora terminalis, and the outer surface of this sleeve is established a bulge loop, forms several engages keyways on the bulge loop; One compression ring is set in the outer surface of sleeve, and a side of this compression ring is established several driving keys and stretched into engages keyways at sleeve, and is subjected to the engages keyways rotary driving, and this compression ring side is in addition established several grinding tooths; One swivel becket is set in the outer surface of sleeve, establishes to nibble groove and be meshed with the grinding tooth of compression ring; One elastic element is set in sleeve outer surface, the ora terminalis of an end contact sleeve, and other holds the contact compression ring; One seal ring is set in the sleeve outer surface between compression ring and swivel becket.

Clip built-in type axle envelope driving component structure of the present utility model, can make assembly working in the rotary machine outside, and after the test ne-leakage situation, be assembled into again in the enclosing cover of rotary machine, so, can avoid this envelope member to be fixed in the rotatingshaft of rotary machine after, need the puzzlement of dismounting again if fluid seepage takes place, and this simple structure, the assembling also comparatively convenient, cost also can reduce.Each position element of the utility model formation design of modularization that is positioned in advance, dismounting all easily when making assembling or test; In addition, push compression ring, spacer element, liner and swivel becket by elastic element in regular turn by the sleeve bottom edge, above-listed each element is suitably configuration in limited space, makes swivel becket really be close to friction with fixing seat ring, prevents the internal liquid seepage.
