Abstract
The utility model discloses a roll which comprises a roller, two flanges and two shaft stubs, and is characterized in that the shaft stubs and the flanges are formed in one piece the two flanges are respectively fixed inside the two ends of the roller which is expanded by heating, and the roller is connected with the two flanges tightly and fixedly after cooling off. The utility model adopts the structure that the flanges and the shaft stubs are formed in one piece, and tight and fixed connection is accomplished between the flanges and the roller through heating assembly, thereby the roller of the utility model has simple structure, fixed connection, good sealing efficacy and reliable function.
Description
Technical field
The utility model relates to a kind of pressure roller, more particularly, relate to a kind ofly be connected firmly, the pressure roller of good seal performance.
Background technique
Existing pressure roller generally comprises a roller, two flanges and two spindle noses, and two flanges are fixedly mounted in respectively on the two ends of roller by welding, and two spindle noses are fixedly mounted on the flange by nut, and like this, spindle nose is connected with roller by flange.
Because the welding of roller and flange, and spindle nose is connected by nut with flange, so the connection that has pressure roller now is not very firm, the sealability between roller and the flange is also bad.
Summary of the invention
The technical problems to be solved in the utility model be on the basis of above-mentioned existing pressure roller, provide a kind of and be connected firmly, the pressure roller of good seal performance.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of pressure roller comprises a roller, two flanges and two spindle noses, and it is characterized in that: above-mentioned spindle nose and flange are one-body molded; Above-mentioned two flanges are installed in respectively in its two end part of roller that add after the thermal expansion, and roller cooling back and flange are closely, be connected securely.
Form an integral body owing to spindle nose and flange are one-body molded, and realize tight, firm being connected by the hot charging mode between flange and the roller, so pressure roller of the present utility model is not only simple in structure, and its be connected firmly, good seal performance, usability is reliable.
As further improvement of the utility model, described flange can further be fixedlyed connected by welding with the joint between the roller.
Adopt after this structure, form an integral body owing to spindle nose and flange are one-body molded, and realize tight, firm being connected by the hot charging mode between flange and the roller, so, pressure roller of the present utility model is not only simple in structure, and its be connected firmly, good seal performance, usability is reliable.
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Description of drawings
Accompanying drawing is the structural representation of the utility model preferred embodiment.
In above-mentioned accompanying drawing: 1 is roller, and 2 is flange, and 3 is spindle nose, and 4 is soldering point.
Embodiment
As shown in drawings, a kind of pressure roller comprises a roller 1, two flanges 2 and two spindle noses 3, and above-mentioned spindle nose 3 is one-body molded with flange 2; Above-mentioned two flanges 2 are installed in respectively in roller 1 its two end part that add after the thermal expansion, and roller 1 cooling back and flange 2 are closely, be connected securely; Above-mentioned flange 2 is further fixedlyed connected by welding with the joint between the roller 1, thereby soldering point 4 is left in the joint between flange 2 and roller 1.
Like this, form an integral body owing to spindle nose 3 and flange 2 are one-body molded, and realize tight, firm being connected by the hot charging mode between flange 2 and the roller 1, further strengthen being connected between flange 2 and the roller 1 by welding again, so, pressure roller of the present utility model is not only simple in structure, and its be connected firmly, good seal performance, usability is reliable.
Claims (2)
1. a pressure roller comprises a roller, two flanges and two spindle noses, and it is characterized in that: above-mentioned spindle nose and flange are one-body molded; Above-mentioned two flanges are installed in respectively in its two end part of roller that add after the thermal expansion, and roller cooling back and flange are closely, be connected securely.
2. pressure roller as claimed in claim 1 is characterized in that: described flange is further fixedlyed connected by welding with the joint between the roller.
