Abstract
The utility model relates to a fan provided with an elastic coupling assembly, comprising a fan, a driving shaft connection disc with a shaft sleeve arranged on the driving shaft and a fan securing member. The utility model is characterized in that the fan securing member comprises a ring backing positioned on the driving shaft connection disc, a rubber ring with a circumferential groove on the rim and positioned between the ring backing and a central revolving drum of the fan, a ring pressure disc arranged on the front of the central revolving drum of the fan, and a construction bolt passing through the ring pressure disc, the ring backing and a construction bolt screwed on the driving shaft connection disc, a fan clip is arranged inside the rubber ring notch and the two sides of the rubber ring are pressed by the ring pressure disc and the ring backing respectively. The fan has the advantages of changing a fixed coupling to an elastic coupling, effectively reducing noise, particularly effective during the high-speed operation of generator. Moreover, a large and uniform force-receiving face of the elastic coupling makes the bolt of the fixed fan receive uniform force and prevents it from breakage, thereby greatly improves the reliability and security of the connection and elongates the service life of the fan.
Description
Technical field
The utility model belongs to fan, particularly relates to a kind of fan that the resilient connection assembly is housed.
Background technique
In the cooling system of vehicle motor, fan is a vitals, be to change hub and change a plurality of blades that the hub outer periphery arranges along the center by the center to constitute, be fixed on the live axle by the live axle tie-plate that has axle sleeve and the fan fixing member that are installed on the live axle when mounted, what generally adopt on truck and tractor at present is to use nylon, the flexible fan of injection moldings such as Reinforced Polypropylene, hub is changeed at its center and blade is injection molded into one, for example, what adopt on Perkins Engines is exactly this fan, it is simple in structure, be about to circular metal fan tie-plate and be injection-moulded in the geometrical center that hub is changeed at the center, fan is by the center hole location of fan tie-plate, be evenly equipped with one group of bolt hole on the fan tie-plate, bolt directly passes the fan tie-plate and links as the live axle tie-plate of live axle coupling during installation, and it is fixed on the live axle.Though the fan of said structure has the advantage that cost is low, connect simple and easy accessibility, but because it is a rigid joint with connecting of live axle, position and angle that aft-fan is installed are promptly fixing, if there are deviation in position or angle, then can make fan when high speed rotating, cause the deformable blade inequality, increase noise, and influence wind direction, thereby reduction cooling effect, also may cause the screw unbalance stress of fan attachment in addition, make bolt failure, increase the risk that connects inefficacy, can not guarantee that fan turns round safely and reliably.
Summary of the invention
The utility model can effectively reduce fan noise for the technical problem that exists in the solution known technology provides a kind of, improve the safe and reliable fan that the resilient connection assembly is housed of running.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of fan that the resilient connection assembly is housed, by the flexible fan of injection moulding, live axle tie-plate and fan fixing member that the center on the live axle of being installed in has axle sleeve constitute, described fan fixing member is by the annular backing plate that is installed on the live axle tie-plate, the center that is installed in annular backing plate and fan is changeed outer rim between the hub and is had rubber ring around groove, the annular platen of hub front is changeed at the center that is installed in fan, and pass the construction bolt that described annular platen and annular backing plate be screwedly mounted on the live axle tie-plate successively and form, described fan is installed in the rubber ring annular groove, and the rubber ring both sides are compressed by annular platen and backing plate respectively.
Advantage and the good effect that the utlity model has are: because the utility model adopts annular backing plate, outer rim has the rubber ring around groove, annular platen and construction bolt are formed coupling assembly as fan fixing member, changed the connecting mode of fan, come the two-way center that compresses fan to change hub and live axle tie-plate by the resiliently deformable of rubber ring, form the equally distributed stress surface of symmetry, the change rigid joint is resilient connection, make fan can automatically correct in the running because processing or the fan that causes when installing and the coaxiality deviation of live axle, thereby reduced because the vibration that this deviation caused, reduced noise effectively, also given full play to the radiating effect of fan, especially effect is obvious when high engine speeds turns round, in addition, because this resilient connection stress surface is big and even, make the bolt strained even of fan attachment, avoid the damage of bolt, improved the reliability and the Security that connect greatly, the working life of also having improved fan.The utility model can be widely used in the cooling system of vehicle motor.
