Abstract
The utility model discloses a rotating axle bushing of a saddle support for a heavy duty car. The rotating axle bushing of the saddle support has high load-carrying properties and comprises two unit bushing parts which are made of nylon materials and connected in series. Each unit bushing part is a cylinder-shaped part; a plurality of lubrication grooves are arranged on the inside wall of each bushing part and are in ring array with the axis as the center. One end of the lubrication groove extends to one end face of the bushing to form an open month; the other end of the lubrication groove ends on the inside wall of the bushing part; and the two unit bushing parts are connected in series with the ends of the two bushing parts at the open mouths of the lubrication grooves opposite to each other. The outline of the wall of each lubrication groove is U-shaped, and the straight parts of the U-shape are parallel to the axis. The number of the lubrication grooves is 4.
Description
Technical field
The utility model relates to a kind of heavy-duty car and uses the saddle bearing, is specifically related to a kind of heavy-duty car with saddle bearing rotating shaft lining.
Background technique
In the existing technology, use heavy special-purpose saddle on the heavily loaded tractor, the special-purpose saddle of this heavy type is because structural deficiency has caused saddle spoilage on tractor higher always.Recent development new heavy special-purpose saddle.The former saddle of design object CBR of this saddle assembly exceeds about 10 tons.Because the saddle bearing bears the part axle load of whole saddle assembly and trailer, belongs to the high-mechanic parts, in the special-purpose saddle of heavy-duty car in the past, bearing rotating shaft lining spoilage is higher.
As shown in Figure 1, the lining 1 of former bearing bearing pin 3 outsides is nitrile butadiene rubber cover 2 combinations of φ 30 steel bushing axles and 5mm.Its shortcoming is that the part kind is more, and machining error accumulative total is big, and surface of contact is difficult for cooperating; Nitrile butadiene rubber cover thickness is little, is merely 5mm, and amount of deformation is few, and impact toughness is low, and nitrile butadiene rubber is a kind of common oil resistant rubber, and intensity and elasticity are lower, and wear resistance is general, and static friction coefficient is big (be 0.6-0.9), so easy in torsional fracture under the high-mechanic environment.
Summary of the invention
The technical problem that the utility model will solve provides a kind of heavy-duty car with high-mechanic performance with saddle bearing rotating shaft lining.
In order to solve the problems of the technologies described above, the technological scheme of the utility model is:
A kind of heavy-duty car comprises the unit sleeve member of two series connection of being processed by nylon material with saddle bearing rotating shaft lining, and single sleeve member is a cylindrical tubular member, and the sleeve member inwall has some oil grooves, and oil groove is the center annular array with the axis.
Further, an end of said oil groove extends to an end face of said sleeve member, forms opening, and the other end ends at this sleeve member inwall; Two unit sleeve member are connected with the relative mode of the sleeve member end of oil groove opening.
Again further, the profile line of said oil groove cell wall takes the shape of the letter U, and U-shaped straight section portion is parallel to axis.
Further, the quantity of said oil groove is 4.
The utility model adopts two unit sleeve member strings to be loaded in the bearing rotating shaft, and is simple in structure.Sleeve member material selection nylon material, because the intensity of nylon material and rigidity are high, impact toughness is good, self-lubricating property is good, and on the sleeve member inwall, is provided with oil groove, forms convenient lubricating status, further improves its greasy property.Therefore, the utlity model has the high-mechanic performance, guarantee that lining can reach the load bearing requirements of saddle assembly to it.
Description of drawings
Below in conjunction with accompanying drawing the embodiment of the utility model is done further detailed explanation:
Fig. 1 is the structural representation of lining in the existing technology.
Fig. 2 is the perspective view of the single sleeve member of the utility model.
Fig. 3 is the plan view of Fig. 2.
Fig. 4 is the sectional view of Fig. 3.
Among the figure: 1 lining, 2 nitrile butadiene rubber covers, 3 bearing bearing pins, 4 oil grooves, 5 sleeve member.
Embodiment
Shown in Fig. 2 to 4, heavy-duty car comprises the unit sleeve member 5 of two series connection of being processed by nylon material with saddle bearing rotating shaft lining.Single sleeve member 5 is a cylindrical tubular member, and sleeve member 5 inwalls have some oil grooves 4, and oil groove 4 is the center annular array with the axis.
As further detailed description, an end of said oil groove 4 extends to an end face of said sleeve member 5, forms opening, and the other end ends at this sleeve member inwall.Two unit sleeve member 5 are connected with the relative mode of sleeve member end of oil groove 4 openings.
As further detailed description, the profile line of said oil groove 4 cell walls takes the shape of the letter U, and U-shaped straight section portion is parallel to axis.
As further detailed description, the quantity of said oil groove 4 is 4.Oil groove 4 openings of two unit sleeve member 5 circumferentially stagger 45 °.
The utility model effectively solves existing technology saddle bearing spoilage problem of higher on tractor, and makes that the seat structure transition is mild, span is big, bearing capacity is big.
