Abstract
The utility model relates to a side-direction roller bearing for large-tonnage. The side-direction roller bearing comprises a side roller and a side roller shaft. The side-direction roller bearing is characterized in that the side roller is installed on the side roller shaft in sleeved mode, and rolling needles or rolling columns are installed between the middle of an inner hole of the side roller and the side roller shaft; and thrust bearings are installed between the end portions of the inner hole of the side roller and the side roller shaft, housing washers of the thrust bearings are tightly attached to the end faces of the side roller, and shaft washers of the thrust bearing rings are in interference fit with the side roller shaft. A plurality of groups of rolling needles or rolling columns are installed between the side roller and the side roller shaft, and large radial load can be borne; and the thrust bearings are used at two axial ends of the bearing, the shaft washers which are designed specially are supplemented, and the requirement that the bearing needs to bear a certain amount of axial force is met. Double-layer elastic rings are used on joints of the shaft washers and the side roller, a certain sealing property is kept, and simultaneously, the shaft washers are prevented from falling apart relative to the bearing. The side-direction roller bearing is reliable and stable in structure and capable of being suitable for the large-tonnage.
Description
Technical field
The utility model relates to a kind of bearing, particularly a kind of large-tonnage side direction roller bearing.
Background technique
Fork truck refer to the member pallet cargo load and unload, the various wheeled carrying vehicle of stacking and short distance transportation, weight transport operation, being widely used in the each department of national economies such as station, harbour, airport, factory, warehouse, is the high-efficiency appliance of mechanized handling, stacking and short distance transportation.The vehicle frame sidesway of fork truck need to use side direction roller bearing, and in use owing to be subject to axial force, serious wear between side wheel and the side roller brackets easily causes stuck phenomenon for it, and working life is low.
Number of patent application 200920314140.0 discloses a kind of side wheel bearing, and it comprises mandrel, is set with the outer ring at mandrel, establish needle roller between mandrel and the outer ring, establish thrust ring at the needle roller two ends, thrust ring is by the snap ring axial restraint, and the seal ring that is socketed on the mandrel is established in the end of outer ring.Although this structure utilizes thrust ring and snap ring to the outer ring axial limiting, improve the axial bearing capacity of bearing, its axial bearing capacity is limited, can't be applicable to the large-tonnage fork truck, uses to be subject to narrow limitation.
Summary of the invention
The technical problems to be solved in the utility model provides the reliable large-tonnage of a kind of structural stability side direction roller bearing.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of large-tonnage side direction roller bearing, comprise side wheel, sidewinder wheel shaft, its innovative point is: described side wheel is sleeved on and sidewinders on the wheel shaft, side wheel endoporus middle part and sidewinder needle roller or roller are set between the wheel shaft; The coaxial diameter that arranges in side wheel endoporus two ends is greater than the thrust-bearing mounting hole of endoporus, thrust-bearing mounting hole and sidewinder and be provided with thrust-bearing between the wheel shaft, the seat ring of described thrust-bearing is close to the rib that forms between thrust-bearing mounting hole and the endoporus, the blowout patche of thrust-bearing with sidewinder the wheel shaft interference fit.
Further, the joint of described blowout patche and side wheel endoporus is provided with the Double-layer elastic circle.
Further, described blowout patche with sidewinder wheel shaft by realizing over-surplus fit structure at both joints pressure injection rubber.
Further, described blowout patche stretches out the exterior edge face of side wheel at axial position.
The utility model has the advantage of: side wheel and sidewinder between the wheel shaft many group needle rollers or rollers are installed, can bear larger radial load; Thrust-bearing is used at axial two ends at bearing, is aided with custom-designed blowout patche, satisfies the demand that the bearing needs bear certain axial force.The Double-layer elastic circle is used in the joint of blowout patche and side wheel, keeping certain sealability while, can prevent that again the relative bearing of blowout patche from falling apart, and reliable in structure, stable can be applicable to large-tonnage side direction roller bearing.
Blowout patche with sidewinder wheel shaft by realizing over-surplus fit structure at both joints pressure injection rubber, good seal performance, blowout patche exceeds the side wheel end face at axial position, is beneficial to the side wheel rotation behind the general assembly.
Description of drawings
Fig. 1 is the utility model large-tonnage side direction roller bearing structural representation.
Embodiment
As shown in Figure 1, comprise side wheel 1, sidewinder wheel shaft 2, needle roller 3, seat ring 4, blowout patche 5, thrust needle roller and retainer assembly 6.
Above-mentioned side wheel 1 is sleeved on and sidewinders on the wheel shaft 2, the endoporus of side wheel 1 middle part and sidewinder needle roller 3 or roller are set between the wheel shaft 2.Needle roller 3 or roller have many groups, between the adjacent needle roller group spacer ring can be set as requested, or not establish spacer ring.
Side wheel 1 endoporus two ends arrange diameter greater than the thrust-bearing mounting hole of endoporus, thrust-bearing mounting hole and sidewinder between the wheel shaft 2 and be provided with thrust-bearing, and thrust-bearing adopts thrust needle roller and the retainer assembly 6 of standard, perhaps thrust ball and retainer assembly.The seat ring 4 of thrust-bearing is close to the rib that forms between thrust-bearing mounting hole and the endoporus.The blowout patche 5 of thrust-bearing with sidewinder wheel shaft 2 interference fit, blowout patche 5 with sidewinder wheel shaft by realizing over-surplus fit structures at both joint pressure injection rubber 8, blowout patche 5 stretches out the exterior edge face of side wheel 1 at axial position.
Joint at blowout patche 5 and side wheel 1 endoporus is provided with Double-layer elastic circle 7, the Double-layer elastic structure that this Double-layer elastic circle can be integrally bending, the individual layer elastic ring that also can adopt two openings to stagger.
Claims (4)
1. a large-tonnage side direction roller bearing comprises side wheel, sidewinders wheel shaft, it is characterized in that: described side wheel is sleeved on and sidewinders on the wheel shaft, side wheel endoporus middle part and sidewinder needle roller or roller are set between the wheel shaft; The coaxial diameter that arranges in side wheel endoporus two ends is greater than the thrust-bearing mounting hole of endoporus, thrust-bearing mounting hole and sidewinder and be provided with thrust-bearing between the wheel shaft, the seat ring of described thrust-bearing is close to the rib that forms between thrust-bearing mounting hole and the endoporus, the blowout patche of thrust-bearing with sidewinder the wheel shaft interference fit.
