Abstract
The present invention can connect the Synchronous Transmission that two axles make axis parallel but decentraction.Therefore her requirement to concentricity is no longer harsh to also thinner than hairline.She has cut down noise, eliminates bounce, greatly reduces manufacture difficulty, especially the assembling of the super-huge bent axle of more than 100 tons of quality.Trunnion always can be with overstriking to big as the movement locus of crank arm；The frictional resistance that overstriking is increased is cut down with roller bearing replacement bearing watt, and the inner ring of bearing is directly processed on trunnion；Bearing had not only easily started but also energy-conservation than bearing liner；Present invention performance most special in addition to ease of assembly is the least bit error that digestion makes, so size of longitudinal direction can be very short at this, pivot pin can punch from journal surface and insert.Furthermore, the level that we make concentricity is very high, and the present invention is inside not required to work substantially, therefore the fit clearance of pivot pin almost can be close to 0.
Description
Technical field
For the connection of vuilt-up crankshaft, vuilt-up crankshaft has applied for patent of invention, the patent No. 201710091211.4.
Background technology
Existing universal joint can not meet real universal adjustment.
The content of the invention
Respectively increase a swivel between universal joint and two spindle noses being connected.
Specific embodiment
The support of universal-joint crossed joint is set into entitled yoke；One end of two yoke connection spindle nose is all changed a social system
Into as the structure of connection crossed joint one end, it is double end yoke that this is named；Two groups of axial lines of device to hole of each double end yoke
Axial line that is parallel and intersecting at the double end yoke；Two spindle noses of axle, vertical central lines of original dress yoke are respectively bored into one to lead to
Hole, with two pivot pins respectively by double-headed shaft bolt on the spindle nose of above-mentioned two holes drilled through, crossed joint is still connected by originally,
The order of connection：Spindle nose, double end yoke, crossed joint, double end yoke, spindle nose, and require the axial line energy of two axles and two double end yokes
Any 2 millimeters can be separated with the extended line in a line, two axle axial lines to parallel again；Above-mentioned hole requires with the fit clearance of pivot pin
Can rotate without loosening, pivot pin need to be blocked with jump ring, must not come off.
Social benefit
The present invention can connect the Synchronous Transmission that two axles make axis parallel but decentraction.Therefore her requirement to concentricity is not
It is harsh to also thinner than hairline again.She has cut down noise, eliminates bounce, equal to the intensity that increased part, substantially reduces
The assembling of the super-huge bent axle of manufacture difficulty, especially more than 100 tons of quality.In order to save space, the trunnion that will be cut off digs
Sky installs the present invention, hollows out rear overstriking trunnion and makes up its intensity, and horizontal space leeway herein is big, and trunnion can add always
Slightly arrive big as the movement locus of crank arm；The frictional resistance that overstriking is increased is cut down with roller bearing replacement bearing watt, axle
The inner ring for holding directly is processed on trunnion；Bearing had not only easily started but also energy-conservation than bearing liner；The present invention is except ease of assembly
Outer most special performance is the least bit error that digestion makes, so size of longitudinal direction can be very short at this, pivot pin can be from axle journal
Surface punching insertion；In a word, local its difficulty of above-mentioned design change and less, and the difficulty that reduces elsewhere and performance
Improve but very big；Though increased some weight herein, the reinforcement needed for bent axle original " awkward " can be reduced；For total
It, the overall weight of engine will not increase, and power ratio can increase；On the totally unnecessary load of cutting force that pivot pin bears
The heart a, transfer loader shakes on the road jolted and has shaken the more than ten years, and pivot pin who met slight universal joint broke one
Root nail can just bear the body weight of people, by calculating, by experiment.Furthermore, we have made the level of concentricity
It is of the invention to be inside not required to work substantially through very high, therefore the fit clearance of pivot pin almost can be close to " 0 ".So far I
Such big country just made 14 axles altogether, friend's " be stricken with anxiety and fear and earned a nose sweat " in this let us Dalian." sea
Most urgent strengthening the army is required for many super-huge bent axles to foreign strategy " now in addition to super-huge cargo ship, can light group with the present invention
Fill 500 tons of bent axles of weight.
Claims (1)
1. one kind hundred million is to section, it is characterised in that：The support of universal-joint crossed joint is set into entitled yoke；By two yoke
The one end for connecting spindle nose is all changed system into as the structure of connection crossed joint one end, and it is double end yoke that this is named；Each double-headed shaft
The two groups of axis parallels of device to hole pitched and the axial line for intersecting at the double end yoke；By two axles of axle of original dress yoke
Head, vertical central lines respectively bore a through hole, with two pivot pins respectively by double-headed shaft bolt on the spindle nose of above-mentioned two holes drilled through, ten
Byte is still connected by originally, the order of connection：Spindle nose, double end yoke, crossed joint, double end yoke, spindle nose, and require two axles and
The axial line of two double end yokes any can separate 2 millimeters to parallel again with the extended line in a line, two axle axial lines；Above-mentioned hole
Fit clearance requirement with pivot pin can be rotated without loosening, and pivot pin need to be blocked with jump ring, must not come off.
