Embodiment Construction

[0007] A tapered roller bearing stamping cage design improvement, the improved design of the tapered roller bearing stamping cage, the design concept is based on not changing the pressure angle of the cage while increasing the diameter of the cage, as long as the distance between the cage and the outer ring raceway The gap between the cages is greater than the radial momentum of the cage. Such a structure can increase the beam width and the number of rollers, thereby increasing the load and life of the bearing. see table 1

Abstract

The invention discloses a design improvement for a stamping holder of a tapered roller bearing. A novel design concept of the stamping holder of the tapered roller bearing is applied, so that the number of bearing rolling bodies is increased, bearing loads are improved, and the service life of a bearing is prolonged. The design improvement has the beneficial effects that by means of the method, the caliber of the holder is enlarged, the beam width of the holder is increased, the number of rollers is increased, and finally the purposes of improving the loads and prolonging the service life are achieved.

Description

technical field [0001] The invention relates to the technical field of bearing manufacture, in particular to an improvement in the design of a tapered roller bearing stamping cage. Background technique [0002] At present, the design of the tapered roller bearing cage is deduced according to the theoretical tangent point and the intersection point of the tapered roller bearing. However, due to the limitation of the beam width of the cage, the number of rolling elements is also limited, resulting in a low load-carrying capacity of the bearing. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improvement in the design of the stamping cage of the tapered roller bearing which improves the load-carrying capacity of the bearing and increases the service life. [0004] The technical solutions adopted are: [0005] The design improvement of a tapered roller bearing stamping cage is to apply a new tapered roller beari...
