Bearings are used to determine the relative movement position of the rotating shaft and other parts, and play a supporting or guiding role. Bearings have a wide variety of types and are widely used. They are an important component in contemporary machinery and equipment. The quality of the early modeling design directly affects the quality of the post-processing production. This article uses the domestic well-known 3D CAD/CAM software Zhongwang 3D instance operation application to show readers and friends how to quickly carry out 3D CAD modeling of bearings.

The first step is to design the inner and outer rings of the bearing, use the intelligent constraints and parametric sketches of Zhongwang 3D to design the inner and outer rings (see the figure below), and then rotate:

The first Two-step design of rolling elements: (see the figure below)

The third step uses the rolling elements designed in the previous step to design the support frame. When the parameters of the rolling elements are changed, the support frame is also changed. Associative design reduces design modification actions and greatly improves design efficiency:

The fourth step is to assemble, Zhongwang 3D provides simple and practical assembly functions, which can easily and quickly create assembly relationships:

Through the above bearing modeling demonstration operation, Zhongwang 3D's intelligent constraints, parametric sketch design, and assembly functions can quickly carry out early 3D CAD modeling of bearings. To this end, Zhongwang 3D also provides solutions for a large number of customers with this type of demand. It is worth noting that the 64-bit version of Zhongwang 3D2013sp will be launched soon, which enhances the simple and convenient data conversion, supports point contour functions for lofting, improves the calculation accuracy of the minimum tool length, etc., which greatly improves the design efficiency, so stay tuned.
