Detailed Description
The embodiment of the utility model discloses an can combine each other under the condition of not spearing.
Referring to fig. 1 to 12, the present invention discloses various end cone assemblies 100, which include a flange 1, an outer cone housing 2, and an inner cone housing 3 located inside the outer cone housing 2. The flange 1 is provided with mounting holes 11. The outer cone housing 2 is provided with an outer cone insertion portion 21 partially inserted into the mounting hole 11.
Referring to fig. 1 to 8, the outer cone insertion portion 21 has an outer cone edge 211 and an outer cone notch 212 formed by recessing from the outer cone edge 211. The inner cone shell 3 is partially exposed in the outer cone gap 212, and the outer cone shell 2 is welded in the flange 1 by filling the outer cone gap 212. The outer tapered edge 211 is located within the flange 1.
