Abstract
The utility model relates to an improved bending roller which comprises a bearing seat with a bearing inside, a roller body, and coaxial shaft rods extended on two ends of the roller body, wherein a thrust bearing is arranged on the shaft rods on two ends, the bearing is a NU2219 bearing, an angle bearing is further arranged on the shaft rod on end, and the angle bearing is a 7217B angle bearing for bearing axial force. The improved bending roller has the advantages that since the EU2219 bearing is adopted, the radial bearing load is big, the improved bending roller can keep better performance in the environment with relatively rough environment, and meanwhile, the 7217B type angle bearing is adopted for bearing the axial force, and the bearing has the advantages of big bearing load, automatic axial positioning and free manual adjustment, the running use circle of the HV742 type bending machine is led to reach 6 months, and the use condition of an old bending machine is greatly improved.
Description
Technical field
The utility model relates to a kind of crimping roller, especially relates to a kind of architecture advances of crimping roller, belongs to textile machine equipment component technical field.
Background technology
In the prior art, the bad phenomenon that a lot of old crimping machine equipment occur in operation process, the obvious shortening of the life cycle that promptly turns round, the crimping machine of HV742 model particularly, the general provision cycle is six months, can not reach now the service time of expection, have in addition be less than one month; Because wearing out, wear and tear and distortion of crimping machine frame changed reliable installation site of crimping roller or artificial adjustment, the crimping roller bearings at both ends is in the decentraction state, can reduce the service life of bearing, more Zao damage bearing.Now the SL02-4920 bearing that uses has been difficult to the effect that reaches desirable, has also shortened the running life cycle of entire equipment.
The utility model content
The utility model purpose is that a kind of running life cycle is provided in order to overcome the deficiencies in the prior art, meets instructions for use, satisfies the improved crimping roller of manufacturing schedule.
For achieving the above object, the technical solution adopted in the utility model is: a kind of improved crimping roller comprises that the bearing block, roll body, the roll body two ends that are provided with bearing in it are extended with coaxial axostylus axostyle; The axostylus axostyle at described roll body two ends is provided with bearing; Described bearing is the NU2219E bearing.
Described
Bearing is installed in the bearing block 1;
Preferably, describedly wherein also be provided with angle bearing on the end axostylus axostyle, described angle bearing is the 7217B angle bearing, and described angle bearing is installed in the bearing block 1, is used for carrying axial force.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: the bearing that adopts the NU2219E model, radially bearing load is big for it, can under the relative rugged environment of service condition, can keep preferable performance, adopt the angle bearing of 7217B model to carry axial force simultaneously, this bearing advantage: bearing load is big, and the automatic axial location does not need artificial adjustment; Make the running life cycle of crimping roller reach six months, improved the service behaviour of HV742 model crimping machine greatly.Concrete parameter relatively sees the following form:
| Bearing designation | The moving Cr (KN) of basic rated load | Limit speed/r.Min-1 (grease) | Operating position |

Description of drawings
Below in conjunction with accompanying drawing technical solutions of the utility model are described further:
Accompanying drawing 1: be the cutaway view of the structure diagram of the improved crimping roller of the utility model;
Wherein: 1, bearing block; 2, roll body; 3, axostylus axostyle; 4, bearing; 5, angle bearing.
The specific embodiment
Described in the utility model a kind of improved crimping roller as shown in Figure 1 comprises that the bearing block 1, roll body 2, the roll body two ends that are provided with bearing in it are extended with coaxial axostylus axostyle 3; The axostylus axostyle 3 at the two ends of described crimping roller is provided with bearing 4; Described bearing 4 is NU 2219E bearings, also is provided with angle bearing 5 on the described axostylus axostyle 3, and described angle bearing 5 is 7217B angle bearings, is used for carrying axial force; Described thrust bearing 4, angle bearing 5 are arranged in the bearing block 1.
Because the utilization of technique scheme, the utility model compared with prior art has following advantage: the bearing that adopts the NU2219E model, radially bearing load is big for it, can under the relative rugged environment of service condition, can keep preferable performance, adopt the 7217B angle bearing to carry axial force simultaneously, this bearing advantage: bearing load is big, and the automatic axial location does not need artificial adjustment; Make the running life cycle of crimping roller reach six months, improved the service behaviour of old crimping machine greatly.
Below only be concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, or any to move mode dull and stereotyped described in the utility model, all drop within the utility model rights protection scope.
