Thrust bearing with gear
Technical Field
The utility model relates to an air conditioner technical field, in particular to take gear thrust bearing.
Background
The field of cylindrical cabinet machines mainly depends on a wind deflector to swing left and right at present to control the wind outlet direction; however, the swing angle is very small (about only 15 degrees swing left and right, and the air volume is rapidly reduced when the air swings left and right beyond the angle) by the left and right swing of the air deflector, the cylindrical cabinet blows by the cross-flow fan, the vertical size of the cross-flow fan is long, so that a user sits at home, the cross-flow fan of the cylindrical cabinet blows directly to the human body, and the user who blows cold by cold is shaken by the dead and the body is uncomfortable.
A thrust bearing is also adopted by a part of the cylindrical cabinet machine to drive a small part of air outlets at the top of the cylindrical air conditioner to rotate (an evaporator, a motor, a cross-flow fan, an air duct and the like cannot rotate), and other parts still swing at a small angle left and right by an air guide plate of the air outlet, so that the problem that cold air is over against the air blowing of a user cannot be solved; the cylindrical cabinet machine adopts a thrust bearing, the gear and the bearing are separately designed, and the weight of a rotating part of the bearing is only 2-4 kg because only a small part of air outlets at the top of the cylindrical air conditioner are driven, so that the adopted thrust bearing has small load and the plastic deformation is not large.
Based on this, a thrust bearing with a gear, which has a stable structure and a large bearing load, is urgently needed.

Detailed Description
It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
Example 1
Referring to FIGS. 1-3: the thrust bearing with the gear comprises a bearing base 1 and a rotating assembly 2 installed on the bearing base, wherein a gear ring 21 is circumferentially arranged on the rotating assembly 2.
The gear ring in the circumferential direction of the rotating assembly drives the rotating assembly to rotate, so that the load of the rotating body borne by the rotating assembly can be improved, and the rotating assembly is more stable in rotation.
In a specific example, the rotating assembly 2 includes an inner ring 22 and rolling steel balls 23, the inner ring 22 is rotatably mounted on the bearing base 1, a rotating gap is provided between the inner ring 22 and the bearing base 1, and a plurality of rolling steel balls 23 are provided in the rotating gap; the inner side of the inner ring 22 is circumferentially provided with a gear ring 21.
The friction force of the rotating assembly during rotation is reduced by rolling the steel balls, and the rotating efficiency is improved.
In a specific example, the bearing device further comprises an inner ring fixing frame 3, the inner ring fixing frame 3 is installed on the bearing base 1, an inner ring 22 and rolling steel balls 23 are arranged between the inner ring fixing frame 3 and the bearing base 1 in a limiting rotation mode, the bearing device further comprises a rolling steel ball retainer 4, each rolling steel ball 23 corresponds to a sliding groove or a rotating hole in the installation position of the inner ring 22 and the installation position of the bearing base 1, and a plurality of steel ball limiting through holes 41 matched with the rolling steel balls 23 are formed in the rolling steel ball retainer 4.
The inner ring can be well prevented from being separated when rotating through the inner ring fixing frame. The rolling steel ball retainer can better keep the rolling steel balls to rotate in respective rotating holes or sliding grooves, prevent the balls from colliding with each other, cause energy loss and reduce the rotating rate.
Preferably, the bottom of the steel ball limiting through hole 41 is slightly smaller than the diameter of the rolling steel ball 23, the top of the steel ball limiting through hole 41 is slightly larger than the diameter of the rolling steel ball 23, and the depth of the steel ball limiting through hole 41 is smaller than the diameter of the rolling steel ball 23.

Preferably, the inner ring fixing frame 3, the bearing base 1 and the inner ring 22 are all provided with a plurality of reinforcing ribs which are uniformly distributed along the circumferential direction.
The strength of the structure is improved by the uniformly distributed reinforcing ribs.
Specifically, screw through holes which are correspondingly matched are formed between the inner ring fixing frame 3 and the bearing base 1 along the circumferential direction.
The inner ring fixing frame and the bearing base can be detachably and fixedly installed through installing screws in the screw through holes.
