Description
Technical field
The utility model belongs to the belt pulley field, and is especially relevant with a kind of single-way belt pulley of automobile generator with clutch effect.
Background technique
Along with the lifting with rotating speed that improves constantly of generator power, for preventing skidding, single-way belt pulley of automobile generator is just applied on automobile.The flute profile of automobile current generator belt pulley progressively develops into wedge shape by triangle; This is in operation generator and has only obtained good performance; When traditional automobile current generator belt pulley occurs quickening or slows down at motor; It also slows down synchronously along with motor or quickens, and can produce bigger impulsive load, accelerates the wearing and tearing of belt or belt pulley; Belt pulley in the past; Its fixing mode all is that belt pulley is enclosed within on the rotor shaft of generator (what have locatees with semicircle chain point); Fix with hexagon nut then; The disabler that makes generator appears easily that integral body is skidded and in belt pulley, and therefore, traditional automobile current generator belt pulley can not satisfy the automobile industry requirement of high speed development on function.
The model utility content
The purpose of the utility model is need bear bigger load when the engine retard and be prone to the defective of whole skidding and do not have impulsive load when a kind of the deceleration is provided and produce, be difficult for producing the whole automobile tension wheel shaft bearing that skids and have the clutch effect in order to overcome existing single-way belt pulley of automobile generator.For this reason, the utility model adopts following technological scheme:
A kind of single-way belt pulley of automobile generator comprises belt pulley, evenly is provided with the ring wedge groove that several cooperate with belt on the belt pulley; It is characterized in that: described single-way belt pulley of automobile generator also comprises unilateral bearing and mandrel, and the unilateral bearing outer ring is inlaid in the corresponding mounting hole of said belt pulley, and the unilateral bearing inner ring is fitted with mandrel; Make unilateral bearing and described being integrally formed of belt pulley structure, this structure plays the effect of clutch, and the rotor shaft of mandrel and generator is fixed together; Engine shaft is connected through belt transmission with described belt pulley; When motor quickened, the outer ring was moved towards at a high speed synchronously, and the inside and outside circle of unilateral bearing does not have relative rotation; This moment, described single-way belt pulley of automobile generator was in bonding state, and the engine drives generator rotor shaft quickens rotation; When engine retard; The outer ring is moved towards low speed synchronously, and inner ring still continues to run up by inertia, promptly is higher than the outer ring rotating speed; Residual quantity has appearred in rotating speed between the inside and outside circle; The Internal and external cycle of unilateral bearing just has relative rotation, and this moment, described single-way belt pulley of automobile generator was in slipping state, decelerates to and outer ring speed together until inner ring.
As to technique scheme replenish and perfect, the utility model also comprises following technical characteristics:
Described mandrel internal surface is provided with one section screw thread, can through this screw thread with the direct rotational fixation of described single-way belt pulley of automobile generator at generator rotor shaft, the nut of screwing on is again fixed described single-way belt pulley of automobile generator.
Described single-way belt pulley of automobile generator also comprises some standard rolling bearings; Standard rolling bearing is sleeved between mandrel and the belt pulley; This standard rolling bearing is divided equally in the unilateral bearing both sides, reduces the radial and axial load of unilateral bearing, also reduces the wearing and tearing to unilateral bearing simultaneously.
Described standard rolling bearing can be two.
Described unilateral bearing comprises unilateral bearing inner ring, unilateral bearing outer ring, needle roller, retainer and spring; Spring one end is inlaid in the groove of retainer; Needle roller places between spring and the retainer; Retainer is inlaid in to be justified in the unilateral bearing outer ring on the draw-in groove, and retainer and unilateral bearing inner ring are through the needle roller socket.
Described standard rolling bearing can be for being embedded with the deep groove ball bearing of Sealing on the groove of inner ring and outer ring, this deep groove ball bearing can prevent effectively that impurity etc. from getting in the unilateral bearing working life of having improved unilateral bearing.
The beneficial effect that uses the utility model to reach: the utility model is not prone to belt pulley integral body and skids: with nut with the belt pulley rotational fixation on rotor shaft, belt pulley just can not produce slide relative with rotor shaft; Effect with clutch: the moment before engine stop working; Engine crankshaft has an of short duration positive and negative direction swing; And the rotor of generator still can keep former direction to rotate at this moment, thereby has avoided the magnetic coil in the rotor to cause damage because of receiving forward and reverse impact; When reducing engine retard belt pulley the impulsive load that will bear: in the car running process; As motor occurs and quicken suddenly or slow down; Can between driving belt and belt pulley, form an of short duration buffering course; Reduced impact, reached the effect of protection driving belt and belt pulley, prolonged the service time of driving belt and belt pulley effectively belt pulley.
