Description
[technical field]
The utility model relates to the technical field of ball bearing, particularly the technical field of heat sinking ball bearing.
[background technique]
The temperature rise of rolling bearing and temperature distribution state directly affect service behaviour and the working life of main shaft-bearing arrangement.Improving constantly of rolling bearing rotating speed and load, then pivot friction heat-dissipating can be caused sharply to increase, if heat can not get distributing timely and effectively, the temperature of Bearing inner will raise extremely.Temperature is too high, and Bearing inner part surface can be caused to burn even mutually glue together, kill and early time discards, consequence is very serious.Therefore, along with improving constantly of main shaft one bearing arrangement rotating speed and load, the heat dissipation problem of rolling bearing has become needs problem demanding prompt solution, is therefore necessary to propose a kind of heat sinking ball bearing.
[model utility content]
The purpose of this utility model solves the problems of the prior art exactly, proposes a kind of heat sinking ball bearing, the heat that pivot friction produces can be dissipated rapidly, ensures the operating temperature of bearing, prevent Bearing inner part and kill, increase working life.
For achieving the above object, the utility model proposes a kind of heat sinking ball bearing, comprise bearing outer ring, bearing inner race, ball, fender bracket, guard circle, described bearing inner race is installed on bearing outer ring inside, described fender bracket is between bearing outer ring and bearing inner race, described fender bracket is provided with several balls, described ball is between bearing outer ring and bearing inner race, described guard circle is installed on bearing outer ring, described guard circle is provided with several thermal vias, described bearing outer ring upper surface is provided with some heat radiation lugs, the outer wall of described bearing outer ring is provided with several fixed grooves.
As preferably, described ball is spheroidal Metal Ball, and the quantity of described ball is 10, and the interval between every two balls is equal, can reduce the friction of Bearing inner, increases the working effect of bearing.
As preferably; be provided with 3 fixed lobes outside described guard circle, 120 degree, described fixed lobe interval is uniformly distributed, and described guard circle is fixed on bearing outer ring by fixed lobe; guard circle is effectively fixed on bearing outer ring, the connection space of protection bearing enclose.
As preferably, described heat radiation lug is that copper sheet is protruding, the quantity of described heat radiation lug is 9, the height of described heat radiation lug is less than the height of bearing outer ring, heat sink conducts heat made of copper is effective, heat diffusion area is large, can be distributed by the heat of Bearing inner fast, ensures the normal working temperature of bearing.
As preferably, described fixed groove is circular groove, and 90 degree, described fixed groove interval is uniformly distributed, and bearing effectively can be fixed on bearing base.
The beneficial effects of the utility model: the utility model by being provided with radiating fin on bearing outer ring, the radiating fin of sheet is distributed in the upper surface of bearing outer ring uniformly, timely heat fricative in bearing can be distributed, prevent the temperature of Bearing inner from too highly causing Bearing inner part surface to be burnt even mutually gluing together, kill and make bearing premature failure, radiating fin adopts copper product, good heat conduction effect, stability of material is good, not easily corrosion, good heat dispersion effectively can increase the working life of bearing.
Feature of the present utility model and advantage will be described in detail by reference to the accompanying drawings by embodiment.
