They have straight teeth and are generally mounted on parallel shafts. They are designed to exchange speed for torque or vice-versa between input and output shafts, dependent on the gear ratios chosen they can step-up \/ down the output speed or torque.\u003cbr\u003e\r\n\u003cstrong\u003eLubrication: \u003c\/strong\u003eIn most cases standard lubrication by oils or greases is acceptable, gears potentially subject to severe weather or chemical exposure should have their lubrication and protection selected specifically for that application. eg: waterproof grease etc.\u003cbr\u003e\r\n\u003cstrong\u003eMaterial: \u003c\/strong\u003eEN8 Steel - a medium strength steel with good tensile strength manufactured to DIN standards. It can be through hardened and is readily machineable in any state.\u003cbr\u003e\r\n\u003cstrong\u003eBenefits: \u003c\/strong\u003eHigh quality, good tensile strength EN8 Steel, pre-bored to H8 tolerance, high quality off the shelf component.\u003cbr\u003e\r\n\u003cstrong\u003eGear Geometry and Diametral Pitch: \u003c\/strong\u003e The reality of gear geometry and DP (modulus) is it can become quite complicated but the rule of thumb is to \u003cstrong\u003eonly use gears of the same DP together\u003c\/strong\u003e.\u003cbr\u003eThe modulus of an imperial gear is a ratio calculated from the ratio of the number of teeth to the standard diametral pitch diameter in inches. Gear DP must be the same between connecting gears in a drive train, bigger DP ratios have fewer teeth and will transfer larger amounts of power, smaller mod ratios will tend to be in faster and quieter applications.\u003c\/p\u003e","brand":"Drive-Flex","offers":[{"title":"Default Title","offer_id":52063558598997,"sku":"SS20DP\/40B-0.5_INCH","price":69.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0979\/1491\/3109\/files\/20dp_imperial_spur_gear_046930a4-25fa-46c4-a462-9af2a3b0985f.jpg?v=1777463875","url":"https:\/\/simplybearings.de\/products\/ss20dp-40b-0-5-inch","provider":"Simply Bearings Ltd - Ball Bearings, Oil Seals, O-rings, V-Belts, SKF","version":"1.0","type":"link"}
