Abstract
The utility model discloses a water cooling ring of a bearing, belongs to the field of bearing cooling of mechanical equipment and aims at solving a problem that the existing electric eddy current dynamometer bearing adopts natural cooling so that cooling effects are poor, heating is severe and lubricating grease is easy to drain. The water cooling ring of the bearing comprises an outer ring and an inner ring, and a water cooling cavity is arranged between the outer ring and the inner ring. The water cooling ring of the bearing is good in bearing cooling effects, prevents the lubricating grease inside the bearing from draining, enables the bearing to be failure-free and to operate reliably, and mainly applied to the bearing of the electric eddy current dynamometer.
Description
Technical field
The utility model relates to machinery bearing cooling field, is specially a kind of bearing water cooling ring that is used for electric eddy current dynamometer.
Background technique
Existing electric eddy current dynamometer bearing now generally adopts natural cooling.Existing electric eddy current dynamometer bearing generally adopts natural cooling.Along with tested rotating speed of automobile engine progressively improves, its bearing operation linear velocity increases, and it is more serious to generate heat, and causes lubricating grease loss in the bearing, causes damage of bearings.
The model utility content
Adopt natural cooling in order to overcome existing electric eddy current dynamometer bearing, cooling effect is not good, and it is more serious to generate heat, the deficiency that easily causes lubricating grease to run off, the utility model aims to provide a kind of bearing water cooling ring, and this bearing water cooling ring cooling effect is good, reliable.
To achieve these goals, the technological scheme that the utility model adopted is: described bearing water cooling ring, its structural feature be, comprises outer shroud and interior ring, is provided with the water cooling chamber between described outer shroud and the interior ring.
Further, in order to strengthen cooling effect, described outer shroud top is provided with the coolant outlet A that is communicated with the water cooling chamber, and the outer shroud bottom is provided with the cooling water intake B that is communicated with the water cooling chamber.
Described outer shroud is in the same place with interior ring preferred weld.
For the ease of connecting, and form water-cooled and cut the chamber, described in ring be preferably U-loop, and the wall thickness d of ring is preferably 1.5mm～2mm in described.
By said structure, connect by boxing in outer shroud and the U-shaped and to form the water cooling ring, in order to guarantee good heat-conducting, the thick d of U-shaped internal ring wall is 1.5mm～2mm; And be not less than with the installation surface roughness of flange
And ring is an interference fit with the fiting property of flange installation position in described, guarantees that junction plane does not have the gap.Cooling water ring bottom is a cooling water intake, and top is cooling water outlet.
Compared with prior art, the beneficial effects of the utility model are: the utility model makes that the bearing cooling effect is good, has kept the interior lubricating grease of bearing not run off, and the bearing fault-free is reliable.
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
