Abstract

The utility model provides a bracket assembly of an engine fan. The bracket assembly comprises a casing, wherein a bracket shaft is arranged in the casing, both ends of the bracket shaft extend out of the casing, one end of the bracket shaft is provided with a driving gear, and the other end of the bracket shaft is provided with a fan hub. An engine drives the driving gear to rotate, and the driving gear drives the fan hub and a cooling fan arranged on the fan hub to rotate through the bracket shaft. Compared with the prior art, the gear transmission is adopted for the bracket assembly, so as to solve the problems of the prior art that the noise is high by using a belt to drive the fan, the requirement on the space of a front wheel during installation is high, and the engine overheat is caused by insufficient air exhaust amount of the fan due to belt slipping. The bracket assembly has the advantages that the structure is simple, the installation is convenient, the running is stable and reliable, and the noise is low.

Description

A kind of engine blower bracket assembly
Technical field
The utility model relates to a kind of motor, especially a kind of engine blower bracket assembly.
Background technique
At present, cooling fan commonly used on motor is directly to be driven by engine crankshaft belt pulley, so the rate of skidding of belt and the working order of train directly affect rotating speed and the exhaust air rate of fan.When automobile moves under the environment of high load, the low speed of a motor vehicle, high temperature, belt pulley wheel train working condition very severe, and belt slippage might appear, the timely cooled engine of the exhaust air rate of fan at this moment, and " overheated " phenomenon may appear in motor.In addition, this structural type of belt drives cooling fan, higher to relatively narrow and small front end wheel train spatial requirement, be difficult for arranging.The existing deficiency of prior art that Here it is.
Summary of the invention
The technical problems to be solved in the utility model is exactly for the existing deficiency of prior art, and a kind of smooth running, reliable engine blower bracket assembly are provided.
This programme is achieved by the following technical measures: this engine blower bracket assembly comprises housing, is provided with bracket axle in described housing, and housing is stretched out at the two ends of bracket axle, and an end of bracket axle is equipped with actuation gear, the other end is equipped with fan hub.
The two ends of above-mentioned housing are provided with the through hole corresponding with bracket axle, are provided with the lining with housing and bracket axle coupling in through hole.Alleviate the wearing and tearing of bracket axle and housing by lining.
Be provided with oilhole on above-mentioned lining, lubricant oil is lubricated bracket axle by oilhole, reduces the fatigue wear of bracket axle.
Be provided with oil sealing between the end of above-mentioned housing and fan hub, come sealing lubricating oil by oil sealing.
The said fans wheel hub is fixedly connected with bracket axle by fixing bolt, guarantees the stability of bracket axle.
The beneficial effect of this programme can be learnt according to the narration to such scheme, in this engine blower bracket assembly, is provided with bracket axle in its housing, and housing is stretched out at the two ends of bracket axle, and an end of bracket axle is equipped with actuation gear, the other end is equipped with fan hub.The driven by engine actuation gear rotates, actuation gear drives fan hub by bracket axle and the cooling fan that is installed on fan hub rotates, than prior art, after this bracket assembly adopts gear transmission, avoided problem in the available technology adopting belt drive fan, the problem includes: noise is large, and fan exhaust quantity not sufficient that belt slippage cause high to the front end wheel train spatial requirement and the problem of the engine overheat that causes when installing.This bracket assembly is simple in structure, and is easy for installation, and smooth running is reliable, and noise is low.This shows, the utility model compared with prior art has substantive distinguishing features and progress, and the beneficial effect of its enforcement is also apparent.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
In figure, 1 is actuation gear, and 2 is housing, and 3 is bracket axle, and 4 is lining, and 5 is fixing bolt, and 6 is fan hub, and 7 is oil sealing, and 8 is through hole.
Embodiment
For clearly demonstrating the technical characterstic of this programme, below by embodiment, and in conjunction with its accompanying drawing, this programme is set forth.
A kind of engine blower bracket assembly, as shown in Figure 1, it comprises housing 2, be provided with bracket axle 3 in described housing 2, the two ends of housing 2 are provided with the through hole corresponding with bracket axle 38, the through hole 8 on housing 2 is stretched out at the two ends of bracket axle 3, is provided with the lining 4 that mates with housing 2 and bracket axle 3 in through hole 8, is provided with the oilhole that passes through for lubricant oil on lining 4.One end of bracket axle 3 is installed with actuation gear 1, the other end is fixedly connected with fan hub 6 by fixing bolt 5, be bolted on fan hub 6 cooling fan is installed, be provided with oil sealing 7 between the end of housing 2 and fan hub 6, be used for sealing lubricating oil.
During use, actuation gear 1 in this bracket assembly of engine-driving rotates, when actuation gear 1 rotates, synchronously rotate by bracket axle 3 drive fan hub 6 and cooling fan, carry out cooling by cooling fan to motor, after adopting the driving structure of gear drive, can guarantee fan steadily, operation reliably, can carry out in time motor, effectively cooling.In running, lubricant oil enters between lining 4 and bracket axle 3 by oilhole, so that bracket axle 3 is lubricated.
Can pass through existing techniques in realizing without the technical characteristics of describing in the utility model, not repeat them here.
