Heat dissipation bearing applied to tensioning wheel of treadmill

Abstract

The utility model relates to the field of bearings, in particular to a radiating bearing applied to a tensioning wheel of a treadmill, which comprises a tensioning wheel shell, a mounting bearing is limited in the tensioning wheel shell, radiators connected with the tensioning wheel shell are symmetrically arranged at two ends of the mounting bearing, and the radiators are connected with the tensioning wheel shell. The radiator comprises mounting plates which are symmetrically arranged at the two ends of the mounting bearing and connected with the tensioning wheel shell, the mounting plates and the mounting bearing are arranged at intervals, and a plurality of radiating fins are connected to the opposite sides of the two mounting plates; according to the tensioning wheel, heat conduction components such as the installation plate, the heat conduction plate and the cooling fins are arranged on the tensioning wheel shell and the installation bearing, heat generated during overall operation of the tensioning wheel can be rapidly guided out, the heat exchange and heat dissipation effects on the tensioning wheel shell and the installation bearing are achieved, the working temperature of the installation bearing is effectively reduced, and the service life of the tensioning wheel is prolonged. And the service life of the tensioning wheel is prolonged.
