Abstract
The utility model discloses a rolling device for a plate-type heat exchanger moving and pressing plate, belonging to the field of heat exchangers, wherein the rolling device for the plate-type heat exchanger moving and pressing plate provided by the utility model comprises a shaft, rolling wheel frames, bearings, wheel hubs and distance sink tubes, wherein a pair of rolling wheel frames are sleeved on the shaft; a pair of bearings are sleeved on a shaft between the rolling wheel frames; the distance sink tubes are arranged between the rolling wheel frames and the bearings and between the bearings; two ends of the shaft are fastened by a nut and a gasket; and wheel hubs are assembled on outer rings of the pair of bearings; and the bearings and the shaft as well as the wheel hubs are interference fit. According to the rolling device, the assembling of the wheel hubs on the outer rings of the bearings not only plays a role of bearing dustproof effect, but also can prevent abrasion caused by the direct rolling of the bearings, most important is that the contact area of the wheel hubs and a connection fitting is greater than that of the bearings, thus the force endured by the bearings can be distributed uniformly; and the installation of the distance sink tubes not only has a protection effect on the key parts, but also the flexibility of the device is improved.
Description
Technical field
The utility model provides a kind of plate type heat exchanger movable pressure plate to use tourelle, belongs to field of heat exchangers.
Background technique
The plate type heat exchanger movable pressure plate that uses at present with tourelle normally bearing inner ring, outer ring respectively with axle and turning rolls assembling, turning rolls is welded on the movable pressure plate, the rolling through axle drives movable pressure plate and moves.This structure is wanted and can be moved flexibly, must meet the following conditions:
At first, bearing is interference fit with axle and turning rolls.This just has very high requirement for the machining accuracy of axle and turning rolls and bearing cooperation place;
Secondly, will there be higher concentricity in the hole on the two turning rollss installation rear roller frame.
Yet, in the actual production, two turning rollss that contact with bearing and axle two ends, not same operation can machine, and very difficult assurance has identical precision; In addition, two turning rollss are welded on the movable pressure plate both sides, and very difficult assurance has the installation precision that satisfies concentricity requirement; Therefore, machining accuracy and installation precision are difficult to meet the demands, thereby have had a strong impact on the activity flexibility of movable pressure plate.
The model utility content
The purpose of the utility model; Very high to component processing and matching requirements in order to solve existing plate type heat exchanger movable pressure plate exactly with the tourelle works fine; But physical condition is difficult to satisfy the variety of problems of bringing, and provides a kind of New-type plate heat exchanger movable pressure plate to use tourelle.
In order to achieve the above object, the utility model adopts following technological scheme:
A kind of plate type heat exchanger movable pressure plate is used tourelle; Comprise axle, turning rolls, bearing, wheel hub, distance sink tube; Be arranged with a pair of turning rolls on the said axle, be arranged with pair of bearings on the axle between the said turning rolls, be equipped with distance sink tube between said turning rolls and the bearing and between bearing and the bearing; Said axle two ends are fastening with nuts and washers, and said pair of bearings outer ring is equipped with wheel hub.
As preferably, said bearing is interference fit with axle and wheel hub.
The utility model has the following advantages and characteristics owing to adopted above technological scheme:
1, changed the structure that bearing is assemblied in turning rolls, with Bearing Installation top guide bar position in the middle of axle.Its characteristics are that the axle here is that same working procedure processing is accomplished, and can guarantee identical precision, thereby have guaranteed after the two bearings assembling is accomplished identical assembly precision is arranged, and can satisfy the requirement of interference fit simultaneously.
2, assembled a wheel hub at bearing outer ring.This structure can play the dust-tight effect; The wearing and tearing that can avoid bearing directly on top guide bar, to roll bearing outer ring is caused again; Most importantly wheel hub is bigger than the area of contact of bearing and top guide bar with top guide bar, and the power that can bearing be born is disperseed, simultaneously between the two bearings, use distance sink tube between bearing and the turning rolls; Can resist movable pressure plate and bearing caused damage, also play crucial effects for moving flexibly of movable pressure plate because of receiving lateral external forces; With bearing outer ring the wheel hub of assembly relation being arranged, also is that same working procedure processing is accomplished, so satisfying of the machining accuracy here just in time guaranteed assembly precision, makes that bearing outer ring and wheel hub also are interference fit.
3, this equipment is economic, practical.
Description of drawings
Accompanying drawing is used to provide the further understanding to the utility model, and constitutes the part of specification, is used to explain the utility model with the embodiment of the utility model, does not constitute the restriction to the utility model.In the accompanying drawings:
Fig. 1 is the utility model structural representation.
Embodiment
Describe below in conjunction with the preferred embodiment of accompanying drawing, should be appreciated that preferred embodiment described herein only is used for explanation and explains the utility model, and be not used in qualification the utility model the utility model.
As shown in Figure 1, a kind of plate type heat exchanger movable pressure plate is used tourelle, comprises axle 1, turning rolls 2, bearing 3, wheel hub 4, distance sink tube 5; Be arranged with a pair of turning rolls 2 on the axle 1; Be arranged with pair of bearings 3 on the axle 1 between the turning rolls 2, be equipped with distance sink tube 5 between turning rolls 2 and the bearing 3 and between bearing and the bearing, axle 1 two ends are fastening with nuts and washers; The pair of bearings outer ring is equipped with wheel hub 4, and bearing 3 is interference fit with axle 1 and wheel hub 4.
The utility model has changed the structure that bearing is assemblied in turning rolls, with Bearing Installation top guide bar position in the middle of axle.Advantage is that the axle here is that same working procedure processing is accomplished, and not only guaranteeing has identical precision and identical assembly precision, and can satisfy the requirement of interference fit simultaneously.Assembled a wheel hub at bearing outer ring; Can play the effect of bearing dust-tight; The wearing and tearing that can avoid bearing directly on top guide bar, to roll bearing outer ring is caused again; Most importantly big than the area of contact of bearing and top guide bar of wheel hub and top guide bar can be disperseed the power that bearing bears, simultaneously between the two bearings, use distance sink tube between bearing and the turning rolls; Can resist movable pressure plate and bearing caused damage, also play crucial effects for moving flexibly of movable pressure plate because of receiving lateral external forces.With bearing outer ring the wheel hub of assembly relation being arranged, also is that same working procedure processing is accomplished, so satisfying of the machining accuracy here just in time guaranteed assembly precision, satisfies the requirement of bearing outer ring and wheel hub interference fit.The existing structure turning rolls is welded on the movable pressure plate, is difficult to guarantee the concentricity in two holes on the turning rolls, but in this new structure, no matter the concentricity symbol is undesirable, can not exert an influence to moving flexibly of movable pressure plate.Total is to move to drive movable pressure plate through the rolling of wheel hub on top guide bar.
What should explain at last is: the above is merely the mode of execution of explanation the utility model; Be not limited to the utility model; For a person skilled in the art; All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
