Planetary gearbox 1AI · 模型 109421
Technical details The general mechanical transmission consists of a central gear 1 (also called a sun gear), a carrier of satalite, or a lever, satalite (intermediate gear 2) and a gear 3, which is called a ring gear, and is also called a solar gear. The axes of the working body O1, Ok, O3 are located in the central axis of the transmission, while the axis of the intermediate organs O2 is located on the satalite carrier eccentrically. We can bring power to any organ, and take it away from any organ. Planetary gears make up a special group of gears. Unlike ordinary gears, in which all shafts are mounted in the gearbox, planetary gears have the property that at least one shaft is mounted in a movable – rotating member, the so – called “handles”. So, planetary gears are those gears in which at least one main member, in addition to rotating motion around its own axis, also performs rotational motion around another axis. Planetary gears are quite often used, especially in the case when it is necessary to achieve a large transmission ratio, and as small a construction as possible. Planetary gears are divided into two basic groups and they are: Ordinary planetary gears that have a fixed gear in their system Differential gears in which all gears are movable In this case it is a 1AI planetary gear, power is applied to the sun gear, and is removed from the lever. Also, in this case the wreath is fixed. Assignment Design a planetary gearbox based on the given scheme 1AI and prepare complete technical documentation, taking into account the following information: - n1 = 2900 (1/min) – gear 1 speed - n3 = 0 (1/min) – gear 3 speed - P1 = 33 kW – power at the entrance - i0 = -5 – transfer relationship
