Abstract
The utility model relates to a kind of air preheater guide bearing apparatus.The guide bearing apparatus complex structure using at present, bearing wear is serious, and reduce working life, and meanwhile, the centering of expansion set is installed difficulty, and cannot dismantle.Novel guide bearing apparatus is optimized and redesigns existing structure, parts have been simplified, avoided the loss of metallic material, the utilization ratio that has increased metallic material, has reduced manufacture cost, has reduced bearing wear simultaneously, guaranteed the working life of bearing, and having facilitated on-the-spot installation, dismounting, has improved working efficiency.The utility model forms and comprises: guide end axle (1), described guide end axle sleeve is on adapter sleeve (2), on described adapter sleeve, be enclosed within expansion set (3) upper, it is upper that described guide bearing is enclosed within adapter sleeve (4), and described guide bearing is connected with bearing housing (5).The utility model is for air preheater bearing guiding.
Description
technical field:
the utility model relates to a kind of air preheater guide bearing apparatus.
background technique:
air preheater adopts central shaft driving mode more, and it is using the rotatingshaft of preheater as live axle, and the moment of torsion of drive motor is directly delivered on preheater rotor by speed reducer.Can have guide end axle to drive and two kinds of modes of support end axle driving, common is guide end axle driving mode.This driving mode is that guide bearing is contained in to truss center, center, hot junction, maintains rotor rotational axis, and bearing need bear horizontal load effect.As important support and the lubricating component-guide bearing apparatus of guide bearing, its structure and performance have vital impact to the safety and steady operation of bearing and preheater so.The guide bearing apparatus complex structure using at present, bearing wear is serious, and reduce working life, and meanwhile, the centering of expansion set is installed difficulty, and cannot dismantle.Novel air preheater guide bearing apparatus, by structure optimization, has solved above problem.
the deficiencies in the prior art part:
one, the guide bearing apparatus complex structure using at present, bearing wear is serious, and reduce working life, and meanwhile, the centering of expansion set is installed difficulty, and cannot dismantle.
two, in existing air preheater guide bearing apparatus structure, guide bearing case can slide up and down with rotor thermal expansion distortion, but top pressure ring and lower bearing case are very large to the extruding of bearing and friction, have accelerated the wearing and tearing of bearing, have reduced the working life of bearing.Meanwhile, the design of inner expansion set clamping cannot guarantee the coaxality with rotor center, and installation and removal are all very difficult.
summary of the invention:
this practical novel object is to provide a kind of Novel air preheater guide bearing apparatus, solved existing guide bearing apparatus complex structure, preheater is in service, guide bearing casing is larger to bearing wear, and expansion set is when install in adopting, cannot guarantee and the coaxality of rotor center and the size of pretightening force the series of problems such as installation and removal difficulty simultaneously.
above-mentioned object realizes by following technological scheme:
an air preheater guide bearing apparatus, its composition comprises: guide end axle, described guide end axle sleeve, on adapter sleeve, is enclosed within on expansion set on described adapter sleeve, and described guide bearing is enclosed within on adapter sleeve, and described guide bearing is connected with bearing housing.
beneficial effect of the present invention:
1, the utility model guide bearing apparatus has removed expansion oplate, sliding plate, and the parts such as bearing pressure ring, and inner expanding cover locking mode is improved to outside expanding cover locking.After this structure optimization, guide bearing apparatus structure becomes clear, guide bearing case is directly connected with center, hot junction truss by bolt, in service when preheater, when rotor is heated mushroom deformation, guide bearing case upwards expands with truss, and owing to there is no compression and the frictional force of bearing pressure ring, guide bearing can move by trace in casing, has greatly reduced the degree of wear of bearing, has guaranteed the working life of bearing.Meanwhile, the optimization of expansion set external locking structure, can better guarantee and the coaxality of rotor center when expansion set is installed, how left and right side impacting force does not affect rotor, has avoided the generation of rotor swinging state.And the outside installing/dismounting of expansion set and replacing are all very convenient.
, the utility model guide bearing apparatus is optimized and redesigns existing structure, parts have been simplified, avoided the loss of metallic material, the utilization ratio that has increased metallic material, has reduced manufacture cost, has reduced bearing wear simultaneously, guaranteed the working life of bearing, and having facilitated on-the-spot installation, dismounting, has improved working efficiency.
, the utility model solved emphatically existing guide bearing apparatus complex structure, in use, to guide bearing serious wear, expansion set location and installation difficulty, the problem such as cannot dismantle; Existing guide bearing apparatus is redesigned, make the structure of guide bearing apparatus more reasonable, good through test and practical effect.
accompanying drawing explanation:
accompanying drawing 1 is structural representation of the present utility model.
embodiment:
embodiment 1:
a kind of Novel air preheater guide bearing apparatus, its composition comprises: guide end axle 1, and described guide end axle sleeve, on adapter sleeve 2, is enclosed within on described adapter sleeve on expansion set 3, described guide bearing is enclosed within on adapter sleeve 4, and described guide bearing is connected with bearing housing 5.
Claims (1)
