Description
Technical field
The present invention relates to a kind of mechanized equipment field, particularly relate to a kind of hydraulic steering gear adopting cross piece coupling arrangement eliminating the radial additional load of coupling.
Background technique
Coupling is widely used in the transmission field such as machinery, hydraulic pressure, and two axles (driving shaft and driven shaft) that it is used to connect different institutions make it jointly to rotate with the mechanical parts of transmitting torque.Current rigid coupling major part adopts fixed and movable coupling two halves flanged shaft to the close-connected mode transferring power of merging, and this connecting mode often makes coupling be subject to force unbalance due to reasons such as making and installation error and part deformations.Therefore, in actual transmission, coupling is except transmitting torque, can produce radial additional load toward contact to output shaft, thus causes coupling shaft to be out of shape or link vibration, finally affects the normal work of machinery.
Summary of the invention
In order to overcome prior art above shortcomings, the invention provides a kind of hydraulic steering gear adopting cross piece coupling arrangement eliminating the radial additional load of coupling.This invention can eliminate the radial additional load that coupling produces axle by force unbalance, has the advantages such as simple, the easy for installation and maintenance cost of manufacture is low.
The technical solution adopted for the present invention to solve the technical problems is: a kind of hydraulic steering gear adopting cross piece coupling arrangement eliminating the radial additional load of coupling, be made up of half-coupling I, bearing pin I, screw I, hydraulic steering gear adopting cross piece, liquid plastics I, half-coupling II, pin shaft II, screw II, pin shaft III, screw III, liquid plastics II, bearing pin IV and screw IV, described hydraulic steering gear adopting cross piece is arranged between half-coupling I and half-coupling II.The end face of described hydraulic steering gear adopting cross piece adjacent teeth processes two orthogonal, mutual disconnected through holes, article two, the axis of through hole is by the center of hydraulic steering gear adopting cross piece, two short-bore perpendicular to described through-bore axis are processed respectively relative to two sides of tooth at hydraulic steering gear adopting cross piece, bearing pin I, II, III, IV is arranged in described short-bore by Spielpassung, liquid plastics I, II is encapsulated in described two through holes, and with four the port screwing hermetics of screw I, II, III, IV by described two through holes.
When active coupling rotates, it touches the sector closing on bearing pin at first can produce pressure to bearing pin, bearing pin extruding liquid plastics, and then the bearing pin of opposite side is extruded by liquid plastics, opposite side bearing pin is ejected another sector of rear extruding half-coupling, thus make two of half-coupling sectors simultaneously stressed all the time, an overall structure transmitting torque.The symmetric design of hydraulic steering gear adopting cross piece can meet the operating mode of reciprocating rotation.
The invention has the beneficial effects as follows: the hydraulic steering gear adopting cross piece coupling arrangement adopting encapsulation liquid plastics, no matter make to be one-way rotation or reciprocally swinging, coupling each position when transmission is synchronously stressed all the time, eliminate the radial additional load that coupling produces axle by force unbalance, an overall structure transmitting torque, thus avoid the adverse consequencess such as coupling shaft distortion or link vibration, ensure that the connection of machinery is reliable.Kit required for the present invention is few, it is simple, easy for installation to manufacture, and maintenance cost is low, and application area is wider.

Embodiment
Below by embodiment, and by reference to the accompanying drawings, technical solution of the present invention is described in further detail.
Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, eliminate a hydraulic steering gear adopting cross piece coupling arrangement for the radial additional load of coupling, be made up of half-coupling I 1, bearing pin I 2, screw I 3, hydraulic steering gear adopting cross piece 4, liquid plastics I 5, half-coupling II 6, pin shaft II 7, screw II 8, pin shaft III 9, screw III 10, liquid plastics II 11, bearing pin IV 12, screw IV 13.Described hydraulic steering gear adopting cross piece 4 is arranged between half-coupling I 1 and half-coupling II 6, and the end face of described hydraulic steering gear adopting cross piece 4 adjacent teeth processes two orthogonal, mutual disconnected through holes, and the axis of described two through holes passes through the center of hydraulic steering gear adopting cross piece 4.Two short-bore perpendicular to described through-bore axis are processed respectively in the bi-side of the relative tooth of hydraulic steering gear adopting cross piece 4.Bearing pin I 2, pin shaft II 7, pin shaft III 9, bearing pin IV 12 are arranged in described short-bore by Spielpassung, liquid plastics I 5, liquid plastics II 11 is encapsulated in described two through holes, and with screw I 3, screw II 8, screw III 10, screw IV 13 by four port screwing hermetics of described two through holes.
When half-coupling I 1 rotates clockwise, its sector produces pressure to bearing pin I 2, make bearing pin I 2 generation along the displacement of own axes, the displacement of bearing pin I 2 makes liquid plastics I 5 flowing occur and transfer the pressure in pin shaft II 7, contacts after pin shaft II 7 is ejected with another sector of half-coupling I 1.When half-coupling I 1 rotates counterclockwise, its sector produces pressure to pin shaft III 9, pin shaft III 9 is made to produce displacement along own axes, the displacement of pin shaft III 9 makes liquid plastics II 11 flowing occur and transfer the pressure on bearing pin IV 12, contacts after bearing pin IV 12 is ejected with another sector of half-coupling I 1.By two bearing pin-liquid plastics-bearing pin transmission channels of hydraulic steering gear adopting cross piece 4, power is always synchronously delivered to another sector by the stressed at first sector of half-coupling I 1.No matter half-coupling I 1 is one-way rotation or reciprocally swinging, this hydraulic steering gear adopting cross piece connection set ensures that two sectors of half-coupling are simultaneously stressed all the time, the additional load be delivered on axle is zero, an overall structure transmitting torque, effectively prevent the radial additional load that coupling produces axle by force unbalance.
