An air conditioner and its fan component bearing cover waterproof sealing structure

Abstract

The invention discloses an air conditioner and blower fan assembly bearing cap waterproof sealing structure thereof, for solving the problem of water penetration in a bearing chamber. By using the air conditioner and the blower fan assembly bearing cap waterproof sealing structure thereof, even if water is accumulated at a bearing cap, under the sealing effect of a double-layer O-shaped ring, the waterproof effect is exhibited, it is ensured that the inside of the bearing chamber is dry and dustproof, bearings can be prevented from being rusted, the reliability of the bearings is improved, and the operation safety and reliability of a modular dynamo-electric machine are improved; besides, clamps are arranged at the inner layer of the bearing cap, clamping grooves are arranged at the inner circular surface of a motor end cap, and when the bearing cap is forcefully pressed downwards, the clamps and the clamping grooves closely cooperate with each other, and thus a conventional screw screwing mode is replaced; and such a design of the bearing cap and the clamps replaces a bolt pretightening design, arrangement of a tightening moment is unnecessary, boring and tapping at the end cap are unnecessary, anti-loosening measures are reduced, the assembling is simpler and more reliable, and the man hours are greatly reduced.

Description

technical field [0001] The invention relates to the technical field of waterproof sealing of a motor bearing chamber, in particular to a waterproof sealing structure of a bearing cover of an air conditioner and a fan assembly thereof. Background technique [0002] The modular machine is mostly used outdoors, so it is easy to form water accumulation at the end cover of the motor. If there is no sealing measure, the water accumulation can easily enter the bearing chamber, which will not only affect the normal operation of the bearing, but also easily produce rust over time, which will damage the bearing. It is extremely harmful. [0003] Existing structures can refer to figure 1 As shown, the motor in the module machine is installed vertically, that is, it is installed vertically on the ground. There is no seal at the end cover 14 of the motor, and the bearing cover 11 at the end of the bearing 12 is fixed by bolts 13; during use, rainwater will gather at the end of the motor...

AI Technical Summary

Problems solved by technology

[0005] In view of this, the present invention provides a waterproof and sealing structure for the bearing cover of the fan assembly, which solves the problem of the water inlet seal of the motor bearing chamber, prevents the bearing from rusting, ensures that the inside of the bearing chamber is dry and dustproof, and is beneficial to improving the reliability of the bearing.
