Title:
STEERING ENGINE HOUSING
Document Type and Number:
WIPO Patent Application WO/2018/121731
Kind Code:
A1
Abstract:
Provided is a steering engine housing (100), comprising a housing body (10) and a plurality of rotary shafts (20), wherein the housing body (10) comprises a housing upper cavity and a housing lower cavity; the rotary shafts (20) and the housing body (10) are integrally injection-moulded; and the rotary shafts (20) are arranged on the housing upper cavity. Since the steering engine housing (100) and the rotary shafts (20) are integrally injection-moulded, not only are the rotary shafts (20) and the steering engine body fixed securely, but also the distances between each rotary shaft (20) are better controlled, thus a centre distance of a gear mounted on the rotary shaft (20) achieves stable control, thereby reducing the noise of the steering engine. In addition, the assembly processes can be reduced, and without a high requirement with respect to the machining of the rotary shafts (20) and holes where the rotary shafts (20) are mounted, generation efficiency is further improved, saving on a large amount of manufacturing costs, improving the market competitiveness of a product.
