Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Example 1

As shown in fig. 1-2, a differential end cap with good extensibility comprises an end cap body, the end cap body comprises a neck portion 1, a circular table portion 2 and a circular disc portion 3, the neck portion 1, the circular table portion 2 and the circular disc portion 3 are coaxially arranged and integrally formed, the diameter of the neck portion 1 is smaller than that of the circular disc portion 3, one end of the neck portion 1 protrudes out of the front surface of the circular table portion 2, the other end of the neck portion 1 extends to the back surface of the circular table portion, the neck portion 1 is cylindrical and is internally provided with a shaft hole 4, the center surface of the circular table portion 2 is provided with eight through grooves 5, the through grooves 5 can be circular or square, the eight through grooves 5 are uniformly arranged in the circumferential direction by taking the neck portion 1 as the center of the circle, the through grooves 5 can reduce the weight of the whole end cap, the circular disc portion 3 comprises an inner disc portion 7 on the inner side and an outer disc portion 8 on the outer side, the thickness of the inner disc portion 7 is smaller than that of the outer disc portion 8, the through grooves 5 are arranged on the inner disc portion 7, the weight of the whole end cover can be further reduced by setting the thickness of the inner disk part 7 to be thinner than that of the outer disk part 8, as shown in fig. 2, the inner disk part 7 is thinner than that of the outer disk part 8 because a cavity is formed at one side thereof, the outer part of the inner disk part 7 is nearly flush with that of the outer disk part 8, the surface of the disk part 2 is further provided with a plurality of reinforcing ribs 6, the plurality of reinforcing ribs 6 are uniformly and circumferentially arranged at the front of the disk part 3, one end of each reinforcing rib 6 extends to the outer disk part 8, the other end extends to the surface of the disk part 2, one side of the inner disk part 7 is arranged to be flush with the outer disk part 8 for conveniently connecting the reinforcing ribs 6, the reinforcing ribs 6 in the embodiment are welded at the surface of the disk part 3, the welding is more convenient than the ground mode, but the tightness of the connection is poor, for this reason, the reinforcing ribs 6 are arranged at one end of the outer disk part 8 and cover the reinforcing connecting plate 12, the reinforcing connecting plate 12 is coated outside the reinforcing rib 6 like an adhesive tape and welded on the outer disc part 8, the tightness of the connection of the reinforcing rib 6 is improved by additionally welding the reinforcing connecting plate 12, and the reason that the reinforcing connecting plate 12 is selectively additionally welded on the outer disc part 8 is that only the outer disc part 8 has enough area to be welded with the reinforcing connecting plate 12, because the through groove 5 exists on the inner disc part 7, the area which can be used for welding is too small, and the effect of fastening connection which can be played by additionally arranging the reinforcing connecting plate 12 on the inner disc part 7 is limited. The reinforcing ribs 6 and the through grooves 5 are arranged in a staggered mode, one reinforcing rib 6 is welded between every two through grooves 5 on the surface of the disk portion 3, if the reinforcing ribs 6 are arranged through the through grooves 5, the welding part of the reinforcing ribs 6 and the surface of the disk portion 3 is reduced, and the connection tightness of the reinforcing ribs and the through grooves is affected.
