Description

A kind of self-lubricating type shock resistance resistant to corrosion railway car transom

Technical field

The utility model relates to oscillating bearing railway car transom, especially relates to a kind of self-lubricating type shock resistance resistant to corrosion railway car transom.

Background technology

Be unable to do without locomotive hook between rail locomotive point of connection and delay node, it is a swing point of connection that hook delays node.But the swing point of connection of routine cannot meet the requirements such as sealing, self-lubricating, withstanding corrosion, Self-aligning, shock resistance.Along with social progress, the high speed development of locomotive, such conventional train node cannot meet the demand of innovative design and complex working condition, and require more and more higher at current linked vector graph, need hook to delay point of connection and possess service life and the safe reliability that sealing, self-lubricating, withstanding corrosion, Self-aligning, shock resistance etc. require to improve rail locomotive hinged node.

Chinese patent CN202703609U discloses a kind of monorail train carriage connecting device, comprise the draw bar of the carriage chassis connecting bogie truck and the second compartment be arranged on the first compartment, first end and the described bogie truck of described draw bar are that ball-and-socket hinge style is connected, and the second end and the described carriage chassis of described draw bar are that hinge type is connected.Can reduce the barycenter in compartment, and structure is simple, is convenient to safeguard.

Summary of the invention

The purpose of this utility model is to be provided for transom two ends, can realize being connected component opposing oscillatory certain angle, can meet and bob and weave in the middle of point of connection, realize buffering bring all directions to bring impulsive force, and have a kind of self-lubricating type shock resistance resistant to corrosion railway car transom of longer service life and non-maintaining function.

The utility model is provided with left plain radial bearing outer ring, right plain radial bearing outer ring, plain radial bearing inner ring, left inside circle seal ring, right inside circle seal ring, outer ring seal ring, solid lubricant, bolt;

Described left plain radial bearing outer ring and right plain radial bearing outer ring are by bolted, the medial surface of left plain radial bearing outer ring and right plain radial bearing outer ring and the lateral surface mating spherical surfaces of plain radial bearing inner ring, plain radial bearing inner ring and left plain radial bearing outer ring and right plain radial bearing outer ring can relative slidings, rotate and swing, left inside circle seal ring and right inside circle seal ring are tightly placed on plain radial bearing inner ring, and on the lateral surface of plain radial bearing inner ring, fill solid lubricant, outer ring seal ring is tightly placed on left inside circle seal ring, form a shock resistance withstanding corrosion sealing and delay point of connection to cardioid oscillating bearing rail train carriage hook.

The beneficial effects of the utility model are:

1, plain radial bearing outer ring and plain radial bearing inner ring fitting surface are that sphere can relative sliding, have Self-aligning function, can bear alternating overload, impact load and static overload.When plain radial bearing outer ring is fixed, the component of colluding with can being connected with this end of permanent seat be connected with the mandrel other end realizes circumference all directions and rotates and swing certain angle.Effectively can realize stress relief, eliminate the impulsive force that the component of complex space bears, train hook delays and rocks required length among a small circle and can easily give oscillating bearing to balance.Enable train hook delay suffered impulsive force actv. balance dispersion, the stability that available protecting train hook is slow, better protection train safe is stable to travel.

2, seal ring can adopt ageing-resistant, withstanding corrosion, the seal ring that fire-resistant, good springiness, leak tightness are strong, and can completely cut off extraneous moist, corrosive deposit, the environment such as sand and dust operating mode, prevent bearing be oxidized, under meeting bad working environments, increase substantially the service life that train hook delays.

3, plain radial bearing and seal ring are applied to hook and delay above connection structure by the utility model, and using oscillating bearing as rotation core, real implementation space three received strength and hook delay switching performance.Efficiently solve spatial rotational and the three-dimensional power transmission requirement of some point of connection in Complicated Spatial Structure, meet different working condition requirement.

Detailed description of the invention

See Fig. 1 ~ 3, the utility model embodiment is provided with left plain radial bearing outer ring 11, right plain radial bearing outer ring 12, plain radial bearing inner ring 2, left inside circle seal ring 51, right inside circle seal ring 52, outer ring seal ring 6, solid lubricant 3, bolt 4;

Described left plain radial bearing outer ring 11 and right plain radial bearing outer ring 12 fastening by bolt 4, the medial surface of left plain radial bearing outer ring 11 and right plain radial bearing outer ring 12 and the lateral surface mating spherical surfaces of plain radial bearing inner ring 2, plain radial bearing inner ring 2 and left plain radial bearing outer ring 11 and right plain radial bearing outer ring 12 can relative slidings, rotate and swing, left inside circle seal ring 51 and right inside circle seal ring 52 are tightly placed on plain radial bearing inner ring 2, and on the lateral surface of plain radial bearing inner ring 2, fill solid lubricant 3, outer ring seal ring 6 is tightly placed on left inside circle seal ring 51, form a shock resistance withstanding corrosion sealing and delay point of connection to cardioid oscillating bearing rail train carriage hook.

Because the fitting surface of described plain radial bearing outer ring and plain radial bearing inner ring is sphere, therefore there is Self-aligning effect and heavily loaded function.Plain radial bearing outer ring and plain radial bearing inner ring relative sliding, plain radial bearing inner ring can rotate arbitrarily, adopts 4Cr13 stainless steel to cardioid oscillating bearing; Solid lubricant inlaid; Special sealing member; The features such as dustproof and waterproof withstanding corrosion can be played, make the utility model still can have very long service life and non-maintaining function under rugged environment operating mode.

Because the utility model is a kind of closed type self-lubricating type shock resistance erosion resisting railway car transom, seal ring is tightly placed on plain radial bearing inner ring, solid lubricant is filled in plain radial bearing inner ring sphere, form a sealing self-lubricating plain radial bearing type railway car connection structure, wherein solid lubricant is embedded in plain radial bearing inner ring sphere, also can freely rotate under mainly meeting shock resistance, not locking, the Related Technical Issues such as non-maintaining.
