Abstract

The invention discloses a new type of rack, which comprises a rack body (3), gear teeth (1) are arranged on the rack body (3), and a bearing ring (2) is arranged in the rack body (3). The beneficial effects of the invention are: the invention has reasonable design and simple structure. The components and proportions of the rack provided by the present invention are moderate, which greatly improves the heat resistance and heat dissipation of the rack, thereby ensuring the normal operation of the rack and prolonging the service life of the rack, and the rack of the present invention does not contain scarce elements Nickel, molybdenum and manganese have low manufacturing costs, and at the same time, the gear has fewer components, which makes the manufacturing process easier and thus reduces the manufacturing cost.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a novel rack. Background technique [0002] A rack is a special gear with teeth distributed on a bar-shaped body. Racks are also divided into straight toothed racks and helical toothed racks, which are paired with straight toothed cylindrical gears and helical toothed cylindrical gears respectively; the tooth profile of the rack is a straight line instead of an involute (for the tooth surface, it is a plane) , which is equivalent to a cylindrical gear with an infinite pitch circle radius. When the rack is working, problems such as broken teeth, deformation, poor lubrication, fast wear, large vibration and high noise are prone to occur. Contents of the invention [0003] In order to solve the current problem, the present invention provides a new type of rack, which includes a rack body, gear teeth are arranged on the rack body, and a bearing ring is arranged in the rack body. Preferabl...
