Abstract
The utility model relates to a side roller bearing, in particular to a side roller bearing which is applicable to a forklift mast or a fork arm carrier, which comprises a mandrel, wherein an outer ring is sleeved on the mandrel, a roller pin is arranged between the mandrel and the outer ring, a stop ring is respectively arranged at two sides of the roller pin, the stop rings are fixed in the axial direction through a snap ring, and a gasket ring which is sleeved on the mandrel is arranged on the end part of the outer ring. The utility model mainly provides a side roller bearing with small appearance size, good axial bearing capacity and long service life. The side roller bearing solves the technical problems of the prior art that the side roller bearing has large appearance size, large installation space and easy invalidation.
Description
Technical field
The utility model relates to a kind of roller bearing, relates in particular to a kind of side wheel bearing that is applicable on forklift door frame or the goods shelf.
Background technique
Existing bearing is by fixed block; movement parts and rolling element three parts are formed; generally can only finish rotatablely moving of single direction; the roller bearing of using on the door frame of fork truck and the goods shelf has vertical roller bearing and side wheel bearing at present; vertically roller bearing mostly is the radial inflow rolling bearing; the side wheel bearing mostly is the axle sleeve type sliding bearing; during use; vertically roller bearing and side direction roller bearing are installed respectively; common fork truck separate sides roller bearing or do not have axial carrying capacity; boundary dimension is very big; be unfavorable for installing; make the structure of door frame very complicated, need on door frame, open a groove, bearing is sunken in the groove; and in use door frame whenever makes a round trip and will produce once vibration, and bearing was lost efficacy in advance.Existing structure as shown in Figure 1, it is to be made of mandrel 1, outer ring 2 and deep groove ball bearing 7, is socketed with outer ring 2 on mandrel 1, between mandrel 1 and outer ring 2 deep groove ball bearing 7 is set.This structural entity profile is bigger, and required installing space is also just bigger, and axial carrying capacity is not strong.
Summary of the invention
It is little that the utility model has mainly provided a kind of boundary dimension, and axial carrying capacity is good, the side wheel bearing of bearing long service life; The boundary dimension that solves existing in prior technology side wheel bearing is big, and installation footprint is big, easily the technical problem that lost efficacy.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: a kind of side wheel bearing, comprise mandrel, on described mandrel, be socketed with the outer ring, be provided with needle roller between described mandrel and the outer ring, be provided with the thrust circle in the both sides of needle roller, described thrust circle is by the snap ring axial restraint, and the end of described outer ring is provided with the seal ring that is socketed on the mandrel.Between mandrel and outer ring, select reinforced needle roller structure, the load of side wheel bearing is improved more than five times, and boundary dimension also reduced more than 1/5, made door frame to slot, eliminated the vibrations that whenever make a round trip and produce.Simultaneously the thrust circle is set, and fixes, well improved the axial carrying capacity of bearing with snap ring at the two ends of needle roller.
As preferably, described mandrel is provided with groove, and described snap ring is connected in the groove.Utilize groove that snap ring is fixed, simple in structure, easy for installation, the physical dimension compactness.
As preferably, the external diameter of described thrust circle is greater than the external diameter of described snap ring, and the external diameter of described thrust circle is less than the external diameter of described seal ring.Seal ring is used for grease sealing in bearing, prevents that simultaneously impurity from entering, so its external diameter is maximum, and the thrust circle is used for needle roller is fixed, and the width of annular thrust circle is less than the diameter of needle roller, and snap ring is used for the thrust circle is fixed.
As preferably, the diameter of described mandrel is 18～20mm, and the external diameter of described outer ring is 40mm～45mm.After adopting the needle roller structure, the overall dimensions of bearing reduces, and is convenient to install, and saves the space.
Therefore, a kind of side wheel bearing of the present utility model has following advantage: select reinforced needle roller structure between mandrel and outer ring, improved the bearing capacity of side wheel bearing, reduced boundary dimension simultaneously, door frame need not be slotted, eliminated the vibrations that every back and forth movement once produces; Fix at the two ends of needle roller employing activity back-up ring and snap ring, improved the axial carrying capacity of bearing.
Description of drawings:
Fig. 1 is the schematic representation of original a kind of side wheel bearing.
Fig. 2 is the schematic representation of a kind of side wheel bearing of the present utility model.
The concrete thing mode of implementing:
Below by embodiment, and in conjunction with the accompanying drawings, the technological scheme of model utility is described in further detail.
Embodiment:
As shown in Figure 2, a kind of side roll bearing, comprise mandrel 1, the diameter of mandrel 1 is 20mm, being socketed with external diameter on mandrel 1 is the outer ring 2 of 42mm, the needle roller 3 of P6 * 18 is installed between mandrel 1 and outer ring 2, in the both sides of needle roller 3 thrust circle 4 is installed, thrust circle 4 is socketed on the mandrel 1, the width of the thrust circle 4 of annular utilizes snap ring 5 that thrust circle 4 is fixed thrust circle 4 outside less than the diameter of needle roller 3, thereby needle roller 3 is fixed by two ends, assurance needle roller 3 can not gone here and there back and forth, has improved the bearing load ability.Snap ring 5 is able in the groove on the mandrel 1 thrust circle 4 is fixed by being connected to, and the external diameter of snap ring 5 is less than the external diameter of thrust circle 4.Seal ring 6 sealings are adopted in 2 end in the outer ring, and seal ring 6 is socketed on the mandrel 1, and the external diameter of seal ring 6 is greater than the external diameter of thrust circle 4, and seal ring 6 is connected on the convex shoulder of outer ring 2.
Specific embodiment described herein only is that design of the present utility model is illustrated.The utility model person of ordinary skill in the field can make various modifications or replenishes or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
