Abstract
The utility model relates to a kind of axle bed reducing bearing operating temperatures, comprise pedestal, roller and bearing, described pedestal is connected on fixing frame, two cavitys are provided with in described pedestal, a roller is provided with in each cavity, the two ends of described roller are installed on bearing respectively, and described bearing is installed on the inwall of cavity, described roller and rotating shaft synchronous axial system.The utility model structure is simple, adopt the mode of rotating shaft and bearing mediate contact, and be linear contact lay between rotating shaft and roller, thus greatly reduce the heat transmission turning cod, bearing can be run at relatively low temperature, reach protection bearing, reduce the object of high temperature grease consumption, reduce operating cost; Adopt four loading ability of bearing, reduce single bearing capacity, thus reduce the expense of later maintenance.
Description
Technical field
The utility model belongs to technical field of bearings, particularly a kind of axle bed reducing bearing operating temperatures.
Background technique
At present, the rotation of rotating shaft relies on bearing to realize.Rotating shaft coordinates with bearing inner race, and is tending towards geo-stationary, and bearing outer ring is fixed on bearing support, utilizes the revolution of bearing, to reach the object of axis of rotation.
Under worst hot case, the temperature of rotating shaft is relatively high, and bearing should adopt high temperature resistant bearing, and with the use of high temperature resistant lubricating grease.But when practical application, the life-span of high temperature resistant lubricating grease is shorter, as continuous use, consumption is comparatively large, and input cost is higher; As do not added high temperature resistant lubricating grease in time, then very large to the wearing and tearing of bearing, the damage of bearing will be caused in the short time, the long-term stable operation of bearing can not be ensured, add operating cost.
Summary of the invention
The utility model provides a kind of axle bed reducing bearing operating temperatures to reduce rotatingshaft to the heat output of bearing for solving in known technology the technical problem that exists, bearing is made to be in relatively low operating temperature, can for a long time and the object of stable operation to reach bearing, reduce the consumption of material in running simultaneously, finally reach the object reducing operating cost.
The technological scheme that the utility model is taked for the technical problem existed in solution known technology is:
A kind of axle bed reducing bearing operating temperatures, comprise pedestal, roller and bearing, described pedestal is connected on fixing frame, two cavitys are provided with in described pedestal, a roller is provided with in each cavity, the two ends of described roller are installed on bearing respectively, and described bearing is installed on the inwall of cavity, described roller and rotating shaft synchronous axial system.
Described rotating shaft is installed with axle sleeve, and described roller linearly contacts with axle sleeve.
Described roller and the linear surface of contact of axle sleeve are cambered surface.
The outer surface of described roller adopts concave surface, and by two side direction central foveas, the outer surface of described axle sleeve adopts convex surface, by two side direction central protuberance.
Described cavity is divided into upper and lower two-part and is bolted, cavity upper part is positioned at top base, cavity lower part is positioned at bottom base, described cavity upper part and cavity lower part coordinate the cambered surface being formed and coordinate with bearing outside surface, the lower part inwall of described cavity is provided with bearing-type step, and the top of described cavity is divided into unenclosed construction
The advantage that the utility model has and good effect are: the utility model structure is simple, adopt the mode of rotating shaft and bearing mediate contact, and be linear contact lay between axle sleeve and roller, thus greatly reduce the heat transmission turning cod, bearing can be run at relatively low temperature, reach protection bearing, reduce the object of high temperature grease consumption, reduce operating cost; Adopt four loading ability of bearing, reduce single bearing capacity, thus reduce the expense of later maintenance.

Embodiment:
For summary of the invention of the present utility model, Characteristic can be understood further, hereby exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:
Refer to Fig. 1 ~ Fig. 4, a kind of axle bed reducing bearing operating temperatures, comprise pedestal 5, roller 4 and bearing 1, pedestal 5 is connected on fixing frame 6, be provided with two cavitys in pedestal 5, be provided with a roller 4 in each cavity, the two ends of roller 4 are installed on bearing 1 respectively, bearing 1 is installed on the inwall of cavity, roller 4 and rotating shaft 3 synchronous axial system.
Preferably, rotating shaft 3 is installed with axle sleeve 2, roller 4 linearly contacts with axle sleeve 2, can reduce rotating shaft 3 in the course of the work to the heat output of bearing.
Preferably, roller 4 is cambered surface with the linear surface of contact of axle sleeve 2, more preferably, the outer surface of roller 4 adopts concave surface, and by two side direction central foveas, the outer surface of axle sleeve 2 adopts convex surface, by two side direction central protuberance, make rotating shaft 3 in rotary course, due to the gravity of self, reach the object of restriction rotating shaft 3 axial displacement.
Preferably, cavity is divided into upper and lower two-part and is bolted, cavity upper part is positioned at top base, and cavity lower part is positioned at bottom base, and cavity upper part and cavity lower part coordinate the cambered surface being formed and coordinate with bearing 1 outer surface, the lower part inwall of cavity is provided with bearing-type step, for supporting the power of four bearing 1 vertical directions, the top of cavity is divided into unenclosed construction, is bolted upper and lower pedestal, play compression bearing, and the effect of restriction bearing 1 substantially horizontal displacement.
Working procedure of the present utility model is, in the process that rotating shaft 3 is rotated, axle sleeve 2 rotates together with rotating shaft 3, geo-stationary, roller 4 axle sleeve 2 drive next play rotation, between the two for rolling friction, roller 4 is supported on the bearing 1 at two ends, drives bearing inner race to rotate.
Above embodiment is only in order to illustrate that the technical solution of the utility model is not intended to limit, and those of ordinary skill in the field should be appreciated that and still can modify to the embodiment of model utility or carry out equivalent replacement to portion of techniques feature; And not departing from the spirit of technical solutions of the utility model, it all should be encompassed in the technology of the utility model request protection.
