冷冻库用齿轮电动机
摘要：
本发明提供一种冷冻库用齿轮电动机，其可直接在冷冻库内运转的同时，运转效率高且能够以低成本大大延长寿命。在使电动机(12)及减速机(14)一体化且在冷冻库内运转的冷冻库用齿轮电动机(10)中，具备至少2种油封：极低温用油封(第1油封)(30)，在该冷冻库内具有能够密封所述减速机(14)的输入轴(16)的温度特性；准低温用(或者常温用)油封(第2油封)(32)，插入于该极低温用油封(30)的减速机内侧，具有低温侧界限温度高于第1油封的温度特性。
摘要（英）：

The invention provides a geared motor for a refrigerator, which can run directly in a refrigerator with high running efficiency, low cost and a greatly prolonged service life. In the geared motor for a refrigerator (10) which integrates a motor (12) and a speed reducer (14) and runs in a refrigerator, at least two oil seals are included: an oil seal for extremely-low temperatures (the first oil seal) (30), which has a temperature characteristic that can seal the input shaft (16) of the speed reducer (14) in the refrigerator; an oil seal for quasi-low temperatures (or normal temperatures) (the second oil seal) (32), which is inserted into the inner side of the speed reducer of the oil seal for extremely-low temperatures (30) and has a temperature characteristic that the critical temperature at the lower temperature side is higher than that of the first oil seal.
