Abstract
The invention discloses a pure torsion rod device which comprises a main speed reducer. Two connecting bases are connected with the bottom of the main speed reducer, each connecting base is connected with a connecting rod through a pin roll and a knuckle bearing, each connecting rod is connected with one end of a crank through each pin roll and each knuckle bearing, the other end of each crank and a support are in clearance fit, and the supports are fixed on a foundation. The pure torsion rod device is characterized in that the other ends of the two cranks are installed at the two ends of a torsion rod in a sleeved mode respectively to fix the torsion rod. Counter torque produced by output torque of the main speed reducer produces tension and pressure on the connecting bases and the connecting rods, the torsion and the pressure are converted into torque on the torsion rod through the cranks, and the function of balancing the torque of the main speed reducer and the function of buffering impact load can be finally achieved. The pure torsion rod device improves the stress and the deformation state of the torsion rod, and is long in service life, high in reliability, convenient to adjust, disassemble and maintain, low in cost, and applicable to heavy equipment and other equipment provided with flexible transmission devices.
Description
Technical field
The invention belongs to the mechanical transmissioning technology field.Be applicable to the occasion that jumbo and miscellaneous equipment adopt flexible gearing.
Technical background
The crucial flexible member torsion bar of existing torsion bar device acts on when being subjected to moment of flexure, moment of torsion and shearing, and torsion bar is three-dimensional stress state during work under the effect of external force.Design has to adopt high performance material, larger safety coefficient, strict manufacturing requirement, thereby has caused that cost is high, weight is large.Especially from material, process, be assembled to transportation, installation, using all will be everywhere carefully, watch out for constantly, small defective in use all easily rapidly diffusion cause the torsion bar fracture, even cause the substantial equipment accident.
Summary of the invention
The object of the present invention is to provide a kind of pure torsion lever arrangement,
To achieve these goals, by the following technical solutions:
A kind of pure torsion lever arrangement, comprise main reducing gear, the bottom of main reducing gear is connected with respectively two connecting bases, each connecting base is connected with connecting rod by bearing pin and joint shaft bearing, each connecting rod connects a cranked end by bearing pin and joint shaft bearing, and the other end of crank and bearing adopt Spielpassung, and bearing is fixed on the basis, it is characterized in that: the other end of two cranks is set in the torsion bar two ends, and torsion bar is fixed.
The present invention adopts torsion bar as balance and buffer element, by the torsional deflection slowly-releasing load of torsion bar, and torsion bar not by bending stress and shearing stress, has improved the reliability of torsion bar device.
In the use, two connecting rods that link to each other with transmission device main reducing gear shaft axis both sides are subject to draws, pressure, produces moment of torsion by crank at torsion bar, and the torque reaction of torsion bar has realized and the output torque balance in transmission device.When load change that transmission device bears, torsion bar produces the variation of corresponding torsional deflection slowly-releasing load, thereby has cut down spike load, has realized the flexible support effect of transmission device.The pure torsion lever arrangement links to each other with basis and transmission device with bolt, and inner non-standard parts machining manufacturing is simple, and the standard piece buying is convenient and swift, easy accessibility, and repair and maintenance is simple, and cost is low.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the sectional drawing of A-A among Fig. 2.
Among the figure, the 1st, connecting base, the 2nd, connecting rod, the 3rd, crank, the 4th, joint shaft bearing, the 5th, bearing pin, the 6th, torsion bar, the 7th, bearing, the 8th, basis.
Embodiment
The present invention will be further described below in conjunction with the drawings and specific embodiments.
As shown in Figure 1 to Figure 3, when connecting base 1 and connecting rod 2 are subject to External Force Acting, pressure is transferred to moment of torsion on the torsion bar 6 through crank 3, torsion bar 6 produces torsional deflections and realizes the balance of transmission device output torque and the slowly-releasing of load change.The simple assembling of Placement is easy to maintenance between crank 3 and the torsion bar 6.The pure torsion lever arrangement adopts the bolt group to link to each other with transmission device and basis, inner non-standard parts machining manufacturing is simple, the standard piece buying is convenient and swift, easy accessibility, repair and maintenance is simple, torsion bar only bears torsional interaction, is different from existing torsion bar device and also will bears additional moment of flexure and shearing force.
Pure torsion lever arrangement of the present invention has the structure uniqueness, and the characteristics that power transmission is simple and direct are applicable to heavy type, the large-scale flexible transmission device of the industries such as machinery, mine, metallurgy, building materials, the energy.
