Description
Technical field
The utility model relates to a kind of guide bearing assembly of rotary type heat exchanger.
Background technique
As shown in Figure 1, existing rotary type heat exchanger guide bearing assembly comprises guide bearing 3, and guide bearing 3 is located in the guide bearing chock 2, and inner ring is fixing by sleeve pipe 4 and guide end axle 1.Sleeve pipe 4 tops are taper 7, compress by tightening cover 5 and some lock bolts 6, closely cooperate with the tapering part 8 on guide end axle 1 top, and the frictional force of fitting surface can guarantee the smooth running of this drive mechanism.When needs overhaul, can after unclamping lock bolt 6, adopt pressing mode to remove sleeve 4 by the hole in the guide end axle 19.But this structure is very high to the machining required precision of the conical surface, could guarantee that the taper fit face has enough area of contact, provides enough frictional force.But the conical surface high-precision processing is very difficult.In case machining accuracy does not reach requirement, situation about will become flexible.When serious, even lock bolt 6 can be cut off guide end axle 1 and sleeve pipe 4 wearing and tearing.Not only influenced the normal operation of equipment, even may make whole system, caused enormous economic loss by forced-stopping machine.
Summary of the invention
The purpose of this utility model provides a kind of phenomenon of as far as possible avoiding lock bolt to be cut off, thereby improves the reliability of heat exchanger itself, prevents because the guide bearing assembly of the undesired system-down that causes of guide bearing work.
In order to achieve the above object, the technical solution of the utility model has provided a kind of rotary type heat exchanger guide bearing assembly, comprise guide bearing chock, guide bearing is located in the guide bearing chock, it is characterized in that: guide bearing connects by sleeve and guide end axle, the power of holding tightly the transmission that produces by tensioner coupling sleeve assembly between guide end axle and the sleeve.
Further, described tensioner assembly comprises the tensioner coupling sleeve of being located between described guide end axle and the sleeve, is equipped with high-strength bolt in the tensioner coupling sleeve, is with interior ring outside the end of guide end axle, outside interior ring, be with outer shroud, separate by high-strength bolt between interior ring and the outer shroud.
The top of described guide end axle is first cylndrical surface, and described sleeve lining is second cylndrical surface.
The utility model adopts a kind of new transmission bind mode, promptly cancels the conical surface and compresses connecting structure, adopts tensioner coupling sleeve (abbreviation ringfeder) to connect between guide end axle and sleeve pipe.When ringfeder uses,, between ring and the axle, produce the huge power of holding tightly between outer shroud and the profile in making by the effect of high-strength bolt; When bearing load, by the combination force of ringfeder and parts and frictional force transmitting torque, axial force or the combined load of the two that produces together.
The utility model has the advantages that: 1, guide end axle and sleeve pipe do not need to reprocess the conical surface, reduce greatly with respect to conical surface with the junction plane machining accuracy of ringfeder, and manufacturing is simple, and cost reduces.2, ringfeder is installed simply, and is easy to adjust, need not to adopt pressuring method, saved special tools such as oil pump, and it is simple that the structure of guide end axle also becomes.3, ringfeder reliability height, intensity is big, long service life.Even the ringfeder overload only loses the connection effect, can be without prejudice by protection equipment.4, ringfeder is a standard piece, and dismounting is simple, has good interchangeability.Even overload damages in using, also can change fast and damage equipment not.

Embodiment
Specify the utility model below in conjunction with embodiment.
Embodiment
As shown in Figures 2 and 3, a kind of rotary type heat exchanger guide bearing assembly that provides for the utility model, comprise guide bearing chock 2, guide bearing 3 is located in the guide bearing chock 2, in guide bearing 3, be provided with guide end axle 10, outside guide end axle 10, be with sleeve 11, be provided with tensioner coupling sleeve 12 between guide end axle 10 and the sleeve 11, be equipped with high-strength bolt 13 in the tensioner coupling sleeve 12, ring 15 in outside the end of guide end axle 10, being with, outside interior ring 15, be with outer shroud 14, separate by high-strength bolt 13 between interior ring 15 and the outer shroud 14.The top of guide end axle 10 is first cylndrical surface 17, and sleeve 11 inwalls are second cylndrical surface 16.
As shown in Figure 4, above-mentioned guide bearing project organization 21 is used for rotor rotary type heat exchanger 18.Characteristics such as rotor rotary type heat exchanger 18 compact structures, heat exchange efficiency height, the life-span is long, operating cost is low are widely used in heat power station, fume environment protection equipment.This heat exchanger generally adopts the vertical layout of main shaft, and a rotor 19 that heat transfer element is housed is arranged, around 20 rotations of heat exchanger central shaft.The gas of different temperatures feeds heat exchanger respectively, and when rotor was in the high-temperature gas, heat-exchanging element absorbed heat, when it changes in the cryogenic gas, and the heat-exchanging element release heat, thus reach the purpose of heat exchange.Supported end axle and block bearing structure are arranged at heat exchanger central shaft 20 bottoms, and top is this guide bearing project organization 21.When rotor 19 rotations, by the combination force between tensioner coupling sleeve 12 and guide end axle 10 and the sleeve 11 and the frictional force transmitting torque that produces together and the combined load of axial force.
