Description
Technical field
The present invention relates to one-way belt sheave, the Ratcheting one-way belt pulley that specifically a kind of unidirectional delivery power reverse on medium-to-high grade automobile current generator is skidded.
Background technique
One-way belt sheave has the function of unidirectional delivery moment, and its internal structure is equivalent to an overrunning clutch.When it adopts roller meshing engagement structure, because roller is in engagement all the time under the effect of spring thrust, belt pulley when oppositely skidding because the effect of surface friction drag can produce higher temperature, cause spring to generate heat and follow the string, grease dries up, the disabler of belt pulley unidirectional delivery moment.Therefore to the surface roughness requirements at roller engagement position, concentricity requirement is all very high, and this position is made up of the circular arc of different curvature radius, and the mode of grinding can not be adopted to improve surface roughness, directly must ensure surface roughness when extrusion moulding, therefore difficulty is higher.
Summary of the invention
The present invention is directed to the problems referred to above, the Ratcheting one-way belt pulley of a kind of reliable operation, long service life is provided.
According to technological scheme of the present invention: a kind of Ratcheting one-way belt pulley, comprise belt pulley, block bearing and mandrel connecting sleeve, described belt pulley is bearing on described mandrel connecting sleeve by two described block bearings, between described belt pulley and described mandrel connecting sleeve, ratchet mechanism is installed, described ratchet mechanism comprises fixed ratchet wheel cover, adjustable ratchet wheel case, spring and spring seat bowl, the end face that described fixed ratchet wheel cover is relative with described adjustable ratchet wheel case is provided with the hook tooth matched, described fixed ratchet wheel cover is fixed on the inwall of described belt pulley, the axial sliding fit of described adjustable ratchet wheel case is on described mandrel connecting sleeve, described spring seat bowl is fixed on the outside of described adjustable ratchet wheel case, described spring fitting is between described adjustable ratchet wheel case and described spring seat bowl, under the thrust of described spring, described adjustable ratchet wheel case and described fixed ratchet wheel cover are in engagement.
Described adjustable ratchet wheel case is arranged on described mandrel connecting sleeve by spline.
Described ratchet mechanism is between two described block bearings.
The outer wall of described belt pulley is provided with anti-avulsion step.
Technique effect of the present invention is: the present invention is provided with the engagement type ratchet mechanism of plane between belt pulley and mandrel connecting sleeve, and carry-over moment when belt pulley rotates forward can not produce skidding friction phenomenon; When belt pulley surmounts running, hook tooth is thrown off voluntarily, and ratchet both ends of the surface have the phenomenon of slight friction, substantially do not produce heat, effectively can improve the working life of one-way belt sheave.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is further described.
In Fig. 1, comprise belt pulley 1, fixed ratchet wheel cover 2, adjustable ratchet wheel case 3, spring 4, spring seat bowl 5, block bearing 6, mandrel connecting sleeve 7, anti-avulsion step 8 etc.
As shown in Figure 1, the present invention is a kind of Ratcheting one-way belt pulley, comprises belt pulley 1, block bearing 6 and mandrel connecting sleeve 7, and belt pulley 1 is bearing on mandrel connecting sleeve 7 by two block bearings 6.Between belt pulley 1 and mandrel connecting sleeve 7, be provided with ratchet mechanism, ratchet mechanism is between two block bearings 6.
Ratchet mechanism comprises fixed ratchet wheel cover 2, adjustable ratchet wheel case 3, spring 4 and spring seat bowl 5.The end face that fixed ratchet wheel cover 2 is relative with adjustable ratchet wheel case 3 is provided with the hook tooth matched, forms the engagement type ratchet of plane.Fixed ratchet wheel cover 2 is fixed on the inwall of belt pulley 1, and adjustable ratchet wheel case 3 axial sliding fit, can axial motion on mandrel connecting sleeve 7, and such as adjustable ratchet wheel case 3 is arranged on mandrel connecting sleeve 7 by spline.Spring seat bowl 5 is fixed on the outside of adjustable ratchet wheel case 3, and spring 4 is arranged between adjustable ratchet wheel case 3 and spring seat bowl 5, and under the thrust of spring 4, adjustable ratchet wheel case 3 and fixed ratchet wheel overlap 2 and be in engagement.
The outer wall of belt pulley 1 being also provided with anti-avulsion step 8, effectively preventing belt pulley 1 from deviating from when running up.
Working principle of the present invention is as follows: the present invention is provided with the engagement type ratchet mechanism of plane between belt pulley 1 and mandrel connecting sleeve 7, under the effect of spring thrust, forward moment is transmitted in two hook tooth engagements, when belt pulley antiport, hook tooth is thrown off, thus realizes the function of unidirectional delivery moment.
Both ends of the surface ratchet of the present invention is in engagement all the time under the effect of spring 4 thrust, can the reliably carry-over moment when belt pulley 1 rotates forward, and can not produce skidding friction phenomenon; When belt pulley 1 surmounts running, hook tooth is thrown off voluntarily, not carry-over moment.When end ratchet is thrown off, both ends of the surface have the phenomenon of slight friction, therefore belt pulley does not in use produce heat substantially, this is obtained for improvement to the working environment of the block bearing 6 at the lubricant grease of the inside and two ends, effectively can improve the working life of one-way belt sheave.
Component of the present invention are few, and structure is simple, assembles also simple.
