译文：DE'RAN GEAR, INC.是一个唐兰多夫公司。唐兰多夫已经设计和建立齿轮传动装置，自1951年以来，一直活跃在齿轮传动装置设计和建造的^严重的应用。自1951年以来一直保持原来的齿轮箱设计连续生产，仍然是我们^流行的尺寸齿轮传动。他的历史，他的名字命名的操作，在六大洲的超过17万齿轮传动，现在提供了^新的设计，将证明更可靠，比以前的设计。寿命长，服务是我们经过验证的商标。
唐兰多夫操作RANDOLPH制造公司从1951年直到1980年，活跃在直角齿轮传动装置的设计和制造。 1980年，形成一个直角齿轮传动制造商，公司DE'RAN GEAR，专注于螺旋桨齿轮泵驱动器市场。
DE'RAN市政和工业齿轮传动装置均采用螺旋锥齿轮，硬化处理，耐磨寿命长，匹配和重叠集，以确保安静的操作。轴承是精密的滚珠和滚柱式，大小，寿命长，可靠的服务。轴承寿命超过AGMA标准。大轴是刚性定位的传递扭矩的齿轮组和高安全性的因素也不会感到疲劳和断裂。
唐兰多夫开始前风扇冷却齿轮驱动器超过30年。会降低风扇冷却油的温度华氏20度或以上。油的温度的降低，将增加一倍的润滑油的使用寿命。此功能提供的DE'RAN齿轮传动，无需额外费用，为客户提供更持久，更耐用的齿轮传动。风扇冷却的模型J20 - G200B用于在不使用冷却水的情况下为50摄氏度的温度下，以防止过度加热的润滑油。型号G250A - F1200A要求的冷却水。
DE'RAN齿轮传动水平的发动机或电动机驱动时使用的所有类型的立式泵。它们是可在很宽的范围内的比例，以适应发动机转速800 rpm到2600转泵300至3600转的速度。
这些齿轮传动装置中的应用，城市供水和污水泵站，消防，防洪。他们^经常使用的立式涡轮泵提水从地下。
在我们的标准保修DE'RAN GEAR一直是2年。还提供延长保修期计划。
我们期待着帮助您使我们的产品适应您特定的应用。
所有DE'RAN齿轮传动是在美国制造和组装。
原文：DE'RAN GEAR, INC., is a Don Randolph Company. Don Randolph has been designing and building gear drives since 1951, and has remained active in designing and building gear drives for the most severe applications. The original Gear Case Design has remained in continuous production since 1951 and is still our most popular size Gear Drive. With a history of more than 170,000 gear drives that bear his name operating on six continents, he now offers the latest designs that will prove even more reliable than those of previous designs. Long life and service are our proven trademark.
Don Randolph operated RANDOLPH MANUFACTURING COMPANY from 1951 until 1980, active in the design and manufacturing of right angle gear drives. In 1980, DE'RAN GEAR, Inc. was formed as a manufacturer of right angle gear drives, concentrating on the propeller pump gear drive market.
DE'RAN Municipal and Industrial gear drives are constructed with spiral bevel gears, case hardened for long wear life, matched and lapped in sets to assure quiet operation. Bearings are precision ball and roller type, sized to give long life and reliable service. Bearing life exceeds AGMA standards. Shafts are large for rigid positioning of gear set and high safety factors for transmitting torque without fatigue and breakage.
Don Randolph began Fan Cooling of Gear Drives more than 30 years ago. Fan Cooling will reduce the oil temperature by 20 degrees Fahrenheit or more. The reduction in oil temperature will double the life of the lubricating oil. This feature is provided on DE’RAN Gear Drives at no extra charge, to provide longer lasting, more durable Gear Drives. Fan cooling of models J20 - G200B is used to prevent over heating of lubricating oil in temperatures of 50 degrees Celsius without use of cooling water. Models G250A - F1200A Require water cooling.
The DE'RAN gear drive is for use with vertical pumps of all types when driven by horizontal engines or electric motors. They are available in a wide range of ratios to adapt engine speeds of 800 rpm to 2600 rpm to pump speeds of 300 to 3600 rpm.
The applications of these gear drives are for municipal water and sewage pumping, fire fighting and flood control. Their most frequent use is lifting water from underground sources by vertical turbine pumps.
At DE’RAN GEAR our standard warranty has always been 2 years. Extended warranty programs are also available.
We look forward to helping you adapt our product to your specific application.
All DE’RAN Gear Drives are manufactured and assembled in the U.S.A.
