Abstract
The utility model relates to a hot roller bearing cooling device, include: a bearing seat; the rotating main shaft is sleeved in the bearing seat and is rotationally connected with the bearing seat; the cooling jackets are sleeved at two ends of the outer wall of the bearing seat; the cooling jacket includes: an annular pipe body in which a cavity for cooling water to flow is provided; a partition plate disposed in the cavity and adapted to partition the cavity; a water inlet hole and a water outlet hole are formed in the annular pipe body; improve the service temperature of the bearing and prolong the service life. Not only reduces the maintenance cost, but also improves the production efficiency and the market competition rate of products.
Description
Technical Field
The utility model belongs to the technical field of the plastic packaging equipment and specifically relates to bearing cooling in the hot-rolling device.
Background
The hot roller bearing of the existing plastic packaging equipment has no cooling device, the bearing runs in a high-temperature environment for 24 hours for a long time, the service life of the bearing is short, and the bearing at the position has relatively large specification and size, high price and complicated disassembly and replacement. Frequent replacement of the bearings increases maintenance cost, reduces production efficiency, and lowers market competitiveness.
In conclusion, how to cool the bearing and prolong the service life of the bearing becomes a problem which needs to be solved urgently by researchers of the company.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: in order to solve the problem that the service life of a bearing in the conventional hot roller device is shortened in a high-temperature running state, a bearing cooling scheme is provided at present, and the service life of the bearing is prolonged.
In order to solve the technical problem, the utility model discloses a following technical scheme:
the utility model relates to a hot roller bearing cooling device, include: a bearing seat; the rotating main shaft is sleeved in the bearing seat and is rotationally connected with the bearing seat; the cooling jackets are sleeved at two ends of the outer wall of the bearing seat; the cooling jacket includes: an annular pipe body in which a cavity for cooling water to flow is provided; a partition plate disposed in the cavity and adapted to partition the cavity; a water inlet hole and a water outlet hole are formed in the annular pipe body;
the cooling jacket is arranged on a bearing seat corresponding to the outside of the bearing, high-temperature heating oil with the temperature of 120-150 ℃ is introduced into the rotating main shaft, and refrigeration circulating water with the temperature of 10-20 ℃ is introduced into the cooling jacket, so that the bearing is ensured to operate at the working temperature of less than 80 ℃, and the purpose of prolonging the service life of the bearing is achieved;
the cooling jacket comprises an annular pipe body; the refrigeration circulating water enters from the water inlet hole and exits from the water outlet hole, and a loop is formed in the jacket, so that the cooling effect is improved; the annular cavity is partitioned by the partition plate.
The utility model has the advantages that: the utility model relates to a hot-rolling bearing cooling device improves bearing service temperature, increase of service life. Not only reduces the maintenance cost, but also improves the production efficiency and the market competition rate of products.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
FIG. 2 is a schematic view of the cooling jacket of the present invention;
in the figure: 1-rotating main shaft, 2-bearing, 3-cooling jacket, 4-bearing seat, 5-annular tube, 6-partition cavity, 7-clapboard, 8-water inlet and 9-water outlet.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
As shown in fig. 1-2, the present invention is a cooling device for a hot roller bearing, comprising: a bearing seat 4; the rotary main shaft 1 is sleeved in the bearing block 4 and is rotationally connected with the bearing block 4 through a bearing 2; the cooling jackets 3 are sleeved at two ends of the outer wall of the bearing block 4; the cooling jacket 3 includes: an annular tube body 5 in which a cavity 6 for cooling water to flow is provided; a partition 7 disposed in the cavity 6 and adapted to block the cavity 6; a water inlet hole 8 and a water outlet hole 9 are formed in the annular pipe body;
the cooling jacket is arranged on a bearing seat corresponding to the outside of the bearing, high-temperature heating oil with the temperature of 120-150 ℃ is introduced into the rotating main shaft, and refrigeration circulating water with the temperature of 10-20 ℃ is introduced into the cooling jacket, so that the bearing is ensured to operate at the working temperature of less than 80 ℃, and the purpose of prolonging the service life of the bearing is achieved;
the cooling jacket comprises an annular pipe body; the refrigeration circulating water enters from the water inlet hole and exits from the water outlet hole, and a loop is formed in the jacket, so that the cooling effect is improved; the annular cavity is partitioned by the partition plate.
The utility model relates to a hot-rolling bearing cooling device improves bearing service temperature, increase of service life. Not only reduces the maintenance cost, but also improves the production efficiency and the market competition rate of products.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
