Description
(1) technical field
The present invention relates to a kind of reinforcement instrument, specifically a kind of booster that increases moment of torsion.
(2) background technology
At present, existing threaded fastener spanner mainly contains common wrench.Can only carry out fastening to the small-sized threaded fastener of some routines or dismounting, inapplicable bigger threaded fastener.Need the securing member that lashing force is big or get rusty for some, adopt some aids such as extension bar and sleeve usually, help the way of the lengthening spanner arm of force to come fastening and dismounting.Some producer and unit adopt hydraulic test, but hydraulic test has shortcomings such as construction inconvenience, price height.At number of patent application is that disclosed " box spanner booster " also has this function in 96226254.4 the utility model patent file, its structure adopts the small Tooth Number Difference Planetary Transmission structural group to become planetary driving device, planetary gear set is contained in the eccentric axial portion of driving shaft, with excessively be connected by crosshead shoe between output shaft, driving shaft rotates, planetary gear on the driving shaft eccentric axial portion is meshed with the tooth of shell, planetary gear rotates and passes to output shaft by crosshead shoe, reach the purpose that increases moment of torsion, but its complex structure, the bearing life of eccentric shaft is short, and driving-chain is longer, and planetary gear processing is complicated, and cost is higher relatively.
(3) summary of the invention
The object of the present invention is to provide a kind of compact conformation, weight little, output torque is big, is fit to multiple spanner transposing, helps the type Wedge booster of the installation and removal of main equipment.
The object of the present invention is achieved like this: it comprises shell and the end cap that covers on shell, fixing internal tooth central gear in the enclosure, off-centre operation generator, type wedge frame with internal tooth central gear coaxial arrangement also are set in the enclosure, have the five equilibrium groove on the type wedge frame, the type wedge is set in the five equilibrium groove, power shaft and off-centre operation generator connect firmly, and output shaft and type wedge frame connect firmly.
The present invention can also comprise some architectural features like this:
1, is connected with the counter-force support on the shell.
2, be provided with bearing between power shaft and end cap and the type wedge frame.
3, the tooth curve of type wedge overcoil and internal tooth central gear is the tooth curve of phase conjugate.
Type Wedge booster of the present invention can make threaded fastener spanner reinforcement, is widely used to be applicable to that big machinery and motor vehicles threaded fastener carry out fastening or dismounting, has compact conformation, and weight is little, and output torque is big, is fit to advantages such as multiple spanner transposing.Novel structure compactness of the present invention adopts the Oscillating Tooth Gear Reducer principle to save the mechanism of small teeth number difference planet gear transmission, and the type wedge of moving through is directly exported by type wedge frame, simplify the structure, make the axial and radial dimension of transmission device all very little, dwindled volume, alleviated weight.The mutual interference of internal gear pair wheel between cog has been avoided in multiple tooth engagement, can make the type wedge contact bearing capacity height, transmission efficiency height with centre tooth simultaneously.The Continuous Contact form of Oscillating Tooth Gear Reducer conjugate tooth profile has been avoided engaging-in impact of nibbling out, the stable drive noiseless.The processing technology of basic building block is uncomplicated, need not increase special equipment.
(4) description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is that the A of Fig. 1 is to view.
(5) specific embodiment
For example the present invention is done description in more detail below in conjunction with accompanying drawing:
In conjunction with Fig. 1 and Fig. 2, the composition of type Wedge booster of the present invention comprises end cap 1, type wedge frame 2, bearing 3, power shaft 4, type wedge 5, internal tooth central gear 6, counter-force support 7, interchangeable spanner 9, output shaft 10, off-centre operation generator 11 and shell 12.Off-centre operation generator 11, type wedge frame 2 and internal tooth central gear 6 coaxial arrangement.Type wedge frame 2 is the members with five equilibrium groove, connects firmly with output shaft 10, and type wedge frame 2 is placed on internal tooth central gear 6 the insides.Internal tooth central gear 6 is fixed on the housing 12.Type wedge 5 rotates around fixed axis, and various wedge is moved by certain characteristics of motion in the gathering sill of type wedge frame 2, and all models wedge contacts with internal tooth central gear 6 simultaneously, and 1/2 type wedge participation engagement can be arranged at most.The tooth curve of type wedge 5 overcoils and internal tooth central gear 6 is the tooth curve of phase conjugate.
The operation principle of patent of the present invention is: based on Oscillating Tooth Gear Reducer (transmission of mobile tooth and small tooth difference planet gear) mechanism, can increase the moment of torsion of output shaft by the transmission of type wedge central gear, can also increase input torque by the effect of counter-force support in the use.The type Wedge booster is made up of three basic building blocks: off-centre operation generator 11, oscillating tooth gear, internal tooth central gear 6.Oscillating tooth gear is made up of type wedge 5 and type wedge frame 2.End cap 1 and shell 12 and assemble power shaft 4 and output shaft 10 in it, wherein bearing 3 and the bearing 8 in power shaft 4 and the end cap 1 cooperates, type wedge transmission group is contained in the eccentric axial portion of power shaft 4, internal tooth central gear 6 is fixed on the housing 12, retarded motion is directly exported by type wedge frame 2 by type wedge 5, three basic building blocks of composing type wedge transmission---off-centre operation generator 11, type wedge frame 2 and internal tooth central gear 6 coaxial arrangement, type wedge frame 2 is placed on internal tooth central gear 6 the insides, type wedge frame 2 is the members with five equilibrium groove, connects firmly with output shaft 10.Type wedge 5 rotates around fixed axis, and various wedge is moved by certain characteristics of motion in the gathering sill of type wedge frame 2.The all models wedge contacts with internal tooth central gear 6 simultaneously, and 1/2 type wedge participation engagement can be arranged at most.
Need cooperate spanner during use, after the driving force input, power shaft 4 clockwise rotates with constant angular velocity ω 1, it drives off-centre operation generator 11, its set center B is rotated around fixed center O, because off-centre operation generator 11 radial dimensions change, generator 11 produces radial thrust, force the type wedge 5 that meshes with central wheel of internal teeth 6 flank profils, move along type wedge frame 2 uniform radially guide grooves.Meanwhile, type wedge 5 is because of being subjected to the constraint of type wedge frame 2, central wheel of internal teeth 6, in the process of moving along central wheel of internal teeth 6 flank profils, repulsive-type maglev wedge frame 2 rotates with constant angular velocity ω 2, be that output shaft rotates with constant angular velocity ω 2, thereby interchangeable spanner 9 cooperates spanner double thread securing member to dismantle, so the type Wedge booster has been realized the effect of reinforcement.In the process of transmission, the type wedge 5 with the engagement of central wheel of internal teeth 6 inoperative flank profils under type wedge frame 2 repulsions, sequentially turns back to the job initiation position of type wedge, has finished its working cycles.Each type wedge can only promote driven member type wedge frame 2 changes certain angle, and the continuous motion of transmission in the type Wedge booster is to realize by taking over job of various wedge.Interchangeable spanner 9 can be changed the box spanner that is fit to according to working condition requirement.
