Abstract
The utility model discloses a bearing type speed adjuster which is suitable for a medium internal combustion machine set and a small-size or miniature internal combustion machine provided with small size, simple structure and low cost. The utility model mainly comprises a base, a fly ball or a fly hammer, a guide shaft sleeve, a rolling bearing and crown bar screw bolt shaft sleeve nuts. The utility model has the advantages of convenient maintains and low cost without purpose-made devices for sealing, lubricating and cooling.
Description
The utility model bearing type speed regulator, the speed regulator that is specially adapted to the small-sized or micro internal combustion engine group that volume is little, simple in structure, cost is low also can be used for the speed regulator of medium-sized internal combustion unit.
In the small-sized or micro internal combustion engine group of domestic production at present, only be used to the following small-sized or minitype gasoline unit of 50CC of planting mechanically, because the characteristics of himself, so be unsuitable for assembling traditional speed regulator, so the following small-sized or minitype gasoline unit of nearly all 50CC does not have arrangements for speed regulation.
The purpose of this utility model provides a kind of bearing type speed regulator of novelty, adopts dry type ball bearing mode flyball or flyball machinery centrifugal governor, and volume is little, simple in structure, cost is low, reliable performance, and is convenient for installation and maintenance.
The utility model bearing type speed regulator takes following mode to realize: bearing type speed regulator main structure has pedestal, flyball or flyball are housed on the pedestal, have several trough on the pedestal, part is used to adorn the plurality of fixed screw, another part is used to adorn several flyballs, flyball is contained in the base seat groove, if adopt flyball then several fixedly flying hammer brackets are housed on the pedestal, is used to install flyball.Flyball and flyball are used to produce centrifugal thrust when pedestal rotates.The pedestal the other end is a guideway, contains grease in the guideway and does oil storage fat chamber, and pedestal and guideway are processed into one.Sliding sleeve is equipped with in the pedestal outside, band inner taper one end matches with flyball or flyball, the other end has installed additional the garden pin has been housed between rolling bearing, sliding sleeve and the pedestal, be used for the location and guarantee slide block and pedestal run-in synchronism, temperature puts push rod bolt sleeve nut is housed in the rolling bearing hole of being equipped with, push rod bolt sleeve nut is equipped with roll adjustment push rod bolt in the push rod bolt sleeve nut, adopt nut and spring washer location.
The bearing type speed regulator is because of having installed a rolling bearing additional on its sliding sleeve parts, transmit the transmission push rod of feedback signal amount power so making contacts with it, part relatively rotates the rubbing contact transmission by traditional mechanical centrifugal speed governor, becomes the Contact Transmission that present nothing relatively rotates friction.So the bearing speed regulator need not resemble and work in the sealing grease chamber that is immersed in and cooling lubricated for it traditional speed regulator that performance simple in structure is reliable, volume is little, the life-span is long so its package unit has, convenient for installation and maintenance, advantages such as cost is low, so be particularly useful for speed regulator, equally also can be used for the speed regulator of medium-sized internal combustion unit as the small-sized or micro internal combustion engine group that volume is little, simple in structure, cost is low.
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is a bearing type governor structure schematic representation.
With reference to accompanying drawing bearing type speed regulator main structure pedestal (1) is arranged, have several trough on the pedestal, flyball (7) is housed in the groove, the pedestal the other end is guideway (9), contain lubricant grease (10) in the guideway, pedestal (1) is processed into one with guideway.Sliding sleeve (2) is equipped with in the pedestal outside, sliding sleeve one end has inner taper and matches with flyball (7) or flyball, the sliding sleeve the other end is equipped with rolling bearing (8), push rod bolt sleeve nut is housed in the rolling bearing hole, roll adjustment push rod bolt (4) is housed in the push rod bolt sleeve nut, can adopts nut and spring washer location.The garden pin is housed between sliding sleeve (2) and the pedestal (1) is used for the two synchronous rotation of location assurance mutually.
Bearing or speed regulator, but be that flyball (or flying piece) base component, bearing or sliding sleeve parts etc. by inner chamber double as oil storage fat chamber are constituted.When installing and using, flyball (or flyball) base component can directly be fixed on the power output spindle unit of internal combustion unit or other and main shaft rotate on proportional parts with screw (or alternate manner), after fixing, an end of base component inner chamber quilt and its fixing end face airtight (grease of chamber can within it).Refill to put the sliding sleeve parts that single face has sealing cover (rolling) bearing are housed, the other end opening of base component is just blocked by the monolateral sealing cover bearing that has on the sliding sleeve parts like this, if its inner chamber has poured into an amount of grease, then when its work, Castor Oil bearing on the one hand infilters the grease in gap between base component and the sliding sleeve parts on the other hand, also can be when mutual axial motion is done in its work, be lubricated, further improve its operating conditions.Transmit the transmission post rod parts of feedback signal amount of power like this, be in contact with one another with it by the bearing on the bearing type speed regulator, when internal combustion engine, just can partly pass through the Contact Transmission of pivoting friction each other by the main body part of the mechanical centrifugal speed governor of traditional flyball (or flyball) (to call traditional speed regulator in the following text) and the transmission push rod of transmission feedback signal amount of power, transmit the feedback signal amount of power of axially reciprocating, become the Contact Transmission of the no pivoting friction of apparatus of the present invention, transmit the feedback power signal amount of axially reciprocating.The present invention just need not traditional speed regulator like this the sort ofly reduces friction, generates heat during for its work and the lubricating cooling oil chamber of the special sealing that increases the service life.So bearing type speed regulator of the present invention is more reliable, convenient for installation and maintenance and cost is low than little, the simple in structure performance of traditional speed regulator volume.So it is particularly suitable for the low small-sized or micro internal combustion engine group of little, the simple in structure cost of volume, also can be used for medium-sized internal combustion unit.
Bearing type speed regulator of the present utility model now successfully is used on the generator set of forming with homemade 40CC petrol engine, 40 yuan of its a complete set of cost less thaies, and shared volume is not as good as 1/4th of traditional speed regulator.
Claims (2)
