Description
Technical field:
The utility model relates to a kind of mechanical structure preventing dust from directly entering bearing, and it belongs to centrifugal fan technical field.
Background technique:
In existing centrifugal fan, in blower fan normal course of operation, air-flow can enter main frame inside by the gap below impeller, a large amount of dust is deposited on bearing by drag effects near bearing, long term accumulation lower bearing very easily damages, greatly reduce the working life of bearing, also reduce the safety reliability of machine.
Therefore, necessary the deficiency solving prior art is improved to prior art.
Model utility content:
The utility model provides a kind of mechanical structure preventing dust from directly entering bearing to solve above-mentioned prior art Problems existing.
The technological scheme that the utility model adopts has: a kind of mechanical structure preventing dust from directly entering bearing, it comprises rotor, support, sensor, bearing, bearing gland and the bearing bracket being provided with mounting hole, described bearing bracket is fixedly connected on support, bearing is arranged in mounting hole, rotor bearing is in bearing, and the upper end of rotor stretches in outside support by mounting hole, bearing gland is fixedly connected on bearing bracket, and bearing is pressed in mounting hole, described mounting hole comprises assembly department and dustproof part, described bearing is placed in assembly department, rotor upper end stretches in outside support by dustproof part, the inwall of described dustproof part is provided with jagged dustproof groove.
Further, the diameter of described assembly department is greater than the diameter of dustproof part.
The utility model has following beneficial effect: the utility model structure is simple, effectively can prevent dust from entering on bearing, considerably increase the working life of bearing in normal course of operation.
Accompanying drawing illustrates:
Fig. 1 is structural drawing of the present utility model.
Fig. 2 is the partial enlargement structural drawing of the utility model middle (center) bearing on bearing bracket.
Wherein:
1-rotor; 2-support; 3-bearing bracket; 4-sensor; 5-bearing; 6-bearing gland; 7-first screw; 8-second screw; 31-mounting hole; 310-assembly department; 311-dustproof part; 312-dustproof groove.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further described.
Please refer to Fig. 1 and Fig. 2, the mechanical structure that the utility model prevents dust from directly entering bearing comprises rotor 1, support 2, sensor 4, bearing 5, bearing gland 6 and is provided with the bearing bracket 3 of mounting hole 31, bearing bracket 3 is fixedly connected on support 2 by the second screw 8, bearing 5 is arranged in the mounting hole 31 on bearing bracket 3, rotor 1 is supported in bearing 5, and the upper end of rotor 1 stretches in outside support 2 by mounting hole 31, bearing gland 6 is fixedly connected on bearing bracket 3 by the first screw 7, and is pressed in mounting hole 31 by bearing 5.
Mounting hole 31 in the utility model comprises assembly department 310 and dustproof part 311, and wherein the diameter of assembly department 310 is greater than the diameter of dustproof part 311.Bearing 5 is placed in assembly department 310, the upper end of rotor 1 stretches in outside support 2 by dustproof part 311, the utility model is entered on bearing 5 by mounting hole 31 for preventing dust, thus affects the working life of bearing 5, and the inwall of dustproof part 311 is provided with jagged dustproof groove 312.
The above is only preferred implementation of the present utility model; should be understood that; for those skilled in the art, can also make some improvement under the prerequisite not departing from the utility model principle, these improvement also should be considered as protection domain of the present utility model.
