Abstract
The utility model provides a bearing cooling device used in the high-temperature environment. A heat radiation centrifugal fan 2 is arranged on a driving axle between a bearing seat and a high-temperature fan; an axial direction air guide holes 4 are arranged in the seat cover 3 of the bearing seat and the shell of the base 5. The air guide hole arranged at the axial direction of the bearing seat is the through hole, and the arrangement of the air guide holes on the cross-section of the bearing seat can be various layouts such as the annular shape, the grid shape, the honeycomb structure, etc. The seat cover 3 and the base 5 of the bearing cooling device can be processed into bar sections according to series; while in use, the section is intercepted according to the required length. The functions of the centrifugal fan and the air guide holes of the bearing cooling device can form a rush of cold air current to reduce the temperature of the bearing; the common bearing can maintain the normal work in the 400 degrees C high-temperature environment.
Description
Technical field
The utility model relates to a kind of cooling unit to the bearing radiating and cooling.Technical background
The maintenance of asphalt highway needs the road pavement heating, and the machinery on maintenance road surface by a high-temperature blower air blast, heats about 400 ℃ hot blast road pavement when work.High-temperature blower, available heatproof is made above 1000 ℃ stainless steel, but its live axle is difficult to process with stainless steel.Simultaneously, bearing and Sealing also are difficult under 400 ℃ of hot environments, continuously running and do not influence its mechanical property.Though on the axle that drives high temperature executive component one end the heat radiation centrifugal blower is housed, that can only have certain thermolysis to the bearing support surface, the heat of bearing support inside is difficult to distribute.
Summary of the invention
The purpose of this utility model is to provide a kind of under 400 ℃ of hot environments, and bearing and axle still can keep a kind of bearing cooling unit of normal mechanical performance.
The technical solution of the utility model is: on the live axle between bearing support and the high-temperature blower, the heat radiation centrifugal blower is installed; In the bearing support shell, axial air-guiding hole is set.
The effect of centrifugal blower and air-guiding hole in the utility model can form one cold airflow and reduce bearing temperature, even general bearing also can be kept proper functioning under 400 ℃ of hot environments.
Description of drawings
Accompanying drawing is the model utility structural drawing.
Embodiment
Introduce the utility model below in conjunction with accompanying drawing.
With reference to accompanying drawing, live axle 1, one termination that is installed in the bearing support is rotated by motor power, and the other end drives high-temperature blower, on the live axle between bearing support and the high-temperature blower, heat radiation centrifugal blower 2 is housed.In the flap 3 and base 5 housings of bearing support, axially air-guiding hole 4 is being set.Air-guiding hole is a through hole axially in bearing support, and the arranging of air-guiding hole on its cross section can be multiple layouts such as ring-type, latticed, cellular structure.Flap 3 of the present utility model and base 5 can be processed into rectangular section bar according to series, during use, intercept according to Len req.
Claims (4)
1, a kind of bearing cooling unit on live axle (1), is equipped with heat radiation centrifugal blower (2), it is characterized in that: in described driving shaft bearing seat housing, axial air-guiding hole (4) is set.
