Technical Field

[0001] This utility model relates to the field of bell-shaped shell technology, and more specifically, to a sealed bell-shaped shell with a heat dissipation structure. Background Technology

[0002] A universal joint, also known as a universal connector, is a mechanical component that enables power transmission at varying angles. It is used in locations where the direction of the drive shaft needs to be changed. It is the "joint" component of the universal joint transmission device in an automotive drive system. The combination of a universal joint and a drive shaft is called a universal joint transmission device, and the bell housing is an important component of the universal joint.

[0003] In the process of using the existing bell-shaped housing to limit the universal joint, the steel balls on the cage slide and rub against the receiving groove inside the bell-shaped housing, which easily generates a lot of heat. Moreover, the outer shell of the existing bell-shaped housing is mostly in a sealed form, which makes it difficult for the heat inside the bell-shaped housing to dissipate, which can easily affect the durability of the bell-shaped housing and reduce its service life.

The outer surface of the connecting ring is surrounded by a plurality of evenly distributed heat dissipation fins. The connecting ring has a protrusion on the side near the bell-shaped shell body, and a heat dissipation fin two that matches the heat dissipation fins is provided on the protrusion.
