RUSH:GEARS公司。螺旋傘齒輪,人字齒輪作為直角需要高效率的驅動器。他們傳遞運動和動力之間的直角(90°)交叉軸的速度比從1:1(斜角)和1.5:1至6:1(坡口)。

斜面和等比傘形齒輪通常是削減20°壓力角的長期和短期的增編所用的系統,以彌補低的齒數的齒輪和小齒輪的齒削弱。

只有等比傘形齒輪的相同數量的齒,俯仰和壓力角,將一起操作。然而,如差分安排在一組,可以使用兩個以上的等斜角。

傘形齒輪和小齒輪中列出的對,并與不同的節距,壓力角或比率的齒輪是不能互換的??扇〉淖齜ㄊ?,當更換磨損的齒輪,以取代的完整集合,特別是在低比率集。

直齒錐齒形式:除了使用的長期和短期的附錄系統,^全的的RUSH齒輪公司。人字齒輪和錐齒輪的尺寸切割的直齒錐齒形式產生。這種形式有一個本地化的齒軸承,齒輪的齒沿縱向運行,因為本地化的齒面接觸,允許在腳趾或腳跟的牙齒沒有重載的齒輪在裝配和操作過程中的一些調整。

“MOUNTING:當錐齒輪和斜切齒輪安裝軸是很重要的是^的90°的間隔,以消除誤對準斜面或斜切。直齒錐齒形式將允許有輕微的調整,裝配,但不應該被用來克服嚴重不對齊的軸。齒輪應安裝在正確的距離從錐形或頂點中心中使用的輪轂的背面與止推軸承,吸收落后推力在這種類型的負債創建。

安裝距離(“MD”)顯示為每個斜切或錐齒輪的尺寸是其相配的齒輪的中心線的距離從一個齒輪的齒輪輪轂的后端。當正確安裝到這個尺寸,這些齒輪的齒的端部,將彼此齊平。如果安裝的距離過長的齒輪不會完全嚙合,從而允許負載集中的間距線以上,并允許過多的齒隙。當距離過短,齒輪可以結合造成過多的熱量,磨損和破損。

潤滑:適當的潤滑是這種類型的負債以確保更長的使用壽命的齒輪和軸承的必要因素。殘余型純礦物潤滑油推薦用于暴露的資產負債,手或浴潤滑。中等粘度油的封閉式齒輪,氣溫適中,在正常運行結果令人滿意。重型壓力或沖擊載荷應用程序,其中中度至高度需要溫和的極壓(EP)潤滑油。具體的建議可以由工程師在這一領域的許多oilcompanies。

RUSH GEARS inc. BEVEL and MITER GEARS are used as right angle drives where high efficiency is required. They transmit motion and power between right angle (90°) intersecting shafts at speed ratios from 1:1 (Miters) and 1.5:1 to 6:1 (Bevels).

Bevel and Miter Gears are usually cut 20° pressure angle with the long and short addendum system being used to compensate for tooth undercut in gears and pinions having low numbers of teeth.

Only Miter Gears of the same number of teeth, pitch and pressure angle, will operate together. However, more than two like miters may be used in a set such as a differential arrangement.

Bevel Gears and Pinions are listed in pairs and are not interchangeable with gears of a different pitch, pressure angle or ratio. It is advisable when replacing a worn gear to replace the complete set, particularly in low ratio sets.

CONIFLEX TOOTH FORM: In addition to using the long and short addendum system, most all RUSH GEARS inc. miter gears and bevel gear sizes are generated cut with the Coniflex tooth form. This form has a localized tooth bearing running lengthwise along the gear tooth and because of the localization of tooth contact permits some realignment of gears at assembly and during operation without heavy loading at the toe or heel of the tooth.

MOUNTING: When mounting bevel and miter gears it is important that shafts be exactly 90° apart to eliminate mis-alignment of bevel or miter. The Coniflex tooth form will permit a slight adjustment in assembly, but should not be used to overcome severely mis-aligned shafts. Gears should be mounted at the correct distance from the cone or apex center with thrust bearings used in back of the hubs to absorb the backward thrust created in this type of gearing.

The MOUNTING DISTANCE ("MD") dimension shown for each Miter or Bevel Gear is the distance from the back end of the gear hub of one gear to the centerline of its mating gear. When properly mounted to this dimension, the ends of the teeth of these gears will be flush with each other. If the mounting distance is too long the gears will not be fully in mesh, thus permitting the load to be concentrated above the pitch line and allowing excessive backlash. When distance is too short, gears may bind causing excessive heat, wear and breakage.

LUBRICATION: Adequate lubrication is a necessary factor in this type of gearing to insure longer life of gears and bearings. Residual type (straight mineral) oils are recommended for exposed gearing, hand or bath lubricated. Intermediate Viscosity oils for enclosed gearing subject to moderate temperatures should prove satisfactory in normal operation. Heavy duty application, where pressures or shock loads are moderate to high require Mild Extreme Pressure (EP) lubricants. Specific recommendations can be made by engineers of the many oilcompanies in this field.
