买一套棋牌app需要多少 www.jbqtck.com.cn 理查德·休伊特和拉爾夫托珀姆于1938年創立的公司。
Richard Hewitt and Ralph Topham founded the company in 1938.
The company was purchased in 1966, by the present owners, and has been run as a family business since then.
Although Hewitt & Topham Ltd possesses a wealth of skill and experience in the general precision engineering fields, the company specialises in the manufacture of custom made gears, including Spur Gears, Single Helical Gears, Double Helical Gears,
Internal and External Involute Splines, Internal and External Straight Splines, Bevel Gears, Spiral Bevel Gears, Worm Gears (also known as worm wheels), Racks, Serrations, Chain Wheels (Sprockets), Ratchets, Gear Grinding, Thread Grinding, and supplies the subcontract and spares market both nationally and internationally. The company prides itself on the quality of its products.
The majority of bevel gearing made is for shafts at right angles to each other, and with the apex of the pitch cones lying at the same point. The size of the tooth diminishes as the cone apex is approached; the contour of the tooth also alters as the tooth size decreases.
Bevel gears feature in a large number of drives including the differential gearing fitted in the rear axle of motorcars, and the drive from the main shaft to the back shaft. They are also used on the drive of many machine tools.
