Description
Technical field
The utility model relates to a kind of engine fan pulley assembly.
Background technique
The drive pulley that tradition is commonly used has flat tyre wheel, vee-pulley, synchronous pulley, multi-wedge belt pulley etc. multiple.Various transmission scheme respectively has pluses and minuses, and certain structures is simple, but it is large to be subject to noise, and the factors such as efficiency is low, and limit speed is low affect, and application area is subject to certain restrictions.
Summary of the invention
Problem to be solved in the utility model is to provide the dynamo belt wheel assembly that a kind of structure is simple, easy to maintenance, limit speed is high, noise is low, the life-span is long, transmission efficiency is high.
The technological scheme that the utility model provides is: a kind of fan belt wheel assembly, the belt pulley comprising central axle sleeve, be located at the bearing on central shaft and be sheathed on bearing, described bearing is two groups, two groups of bearings are sheathed on central shaft respectively, belt pulley, central shaft and two groups of bearings surround an annular space, central shaft is the hollow shaft with inner chamber, central shaft is radially provided with vent, on the central shaft axis body of vent between two groups of bearings, the inner chamber of vent one end UNICOM hollow shaft, the other end UNICOM annular space.
Central shaft of the present utility model is arranged with end ring, and the radial outer end of end ring is embedded on belt pulley.
The utility model is simple for structure, easy to maintenance, limit speed is high, noise is low, the life-span is long, transmission efficiency is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
See Fig. 1, the utility model comprises the belt pulley 1 for transmitting kinetic energy, for the central shaft 2 of fast pulley assembly, for guaranteeing bearing 3 and the bearing 4 of belt pulley smooth rotation, guarantees belt pulley and bearing unit adeciduate back-up ring 5 at work.Belt pulley, central shaft and two groups of bearings surround an annular space 6, and central shaft 2 is for having the hollow shaft of inner chamber.Central shaft 2 is radially provided with vent 2-1, on the central shaft axis body of vent 2-1 between two groups of bearings 3 and bearing 4, the inner chamber 7 of vent 2-1 one end UNICOM hollow shaft 2, the other end UNICOM annular space 6.
The utility model structure is simple, vent 2-1 can guarantee exocoel air circulation in assembly, can ensure that the amount of heat produced in motor and bearing operation process can excrete again by chamber internal and external pressure balance in time, effectively can extend the life-span of bearing and correlated parts.
The utility model is inserted in engine blower bracket holes by central shaft 2, and lock onto on motor with a bolt passing central shaft hole by the utility model assembly, and this Placement is simple and reliable, easy to maintenance, and design is unique.In using process, motor two groups of belts are wrapped in transferring power on race 1-1 and 1-2 respectively; Engine blower is installed on belt pulley end face 1-3.
The utility model belt pulley can adopt the wear resisting cast iron of the high trade mark
,race adopts the multiple wedge slot that can extend belt working life, guarantee stable drive, effectively avoid belt slippage, is provided with the rolling bearing with high-quality performance and carries out with engine support the fan shaft that is connected in pulley centers hole.Belt pulley end face has setting circle boss for installing engine blower and one group of tapped hole.Belt pulley has two groups of grooves, on it, correspondence is wrapped two groups of multi-rib-belts, makes belt pulley have follower and driving wheel two kinds of functions concurrently: not only accepted kinetic energy that power transmits and driven fan turns but also to downstream part transmitting torque.
Claims (2)
