Abstract
The utility model discloses a siamesed metal core MC nylon wheel which belongs to the technical field of the guide rail component, which comprises a wheel core which is made of the metal material and an outer ring which is made of the MC nylon material, wherein the center of the wheel core is provided with a bearing installation hole, a bearing is arranged inside the bearing installation hole, the periphery of the wheel core is provided with a plurality of axial grooves, two sides of the wheel core are also provided with a flange in the radial direction, and the outer ring is integrally cast outside the wheel core. The outer ring is cast outside the wheel core, so the abrasion caused by the direct contact between the pure MC nylon wheel and the bearing can be avoided, and the slip phenomenon can be prevented; unfavorable influence on the bearing and the integral mechanism caused by the little increment or drop of the temperature of the MC nylon wheel can be overcome; the vibration which is produced by the shaking of the nylon wheel can be prevented, the transmission precision is high, and the running service life of the integral mechanism can be improved. The siamesed metal core MC nylon wheel can be applied to the guide rail components which are used in the mechanical fields such as the elevator, the hoisting machinery and the like.
Description
Technical field
The utility model relates to the guide assembly that uses in the mechanical fields such as elevator, elevator machinery, particularly a kind of roller.
Background technology
In elevator, elevator machinery industry, existing a large amount of MC nylon borrows that adopt are made the MC nylon wheel, and this nylon wheel directly is connected outside the wheel shaft by bearing.Because MC nylon is plastic material, and bearing is a metallic material, and the structure of nylon wheel does not have other parts and strengthened and improve, and the property difference that can not desirable satisfy between MC nylon and the bearing in practice concerns.Causing between wheel body and the bearing skidding appears, bearing rocks, in addition, MC nylon is the rising of temperature or expansion or the contraction that reduction produces because of self characteristics, harmful effect to bearing and the generation of whole mechanism, loosening or move about the precision and the service life of influence transmission in the hole as bearing.
The utility model content
The purpose of this utility model provides and a kind ofly can ensure MC nylon wheel transmission precision, the integrated metal coil MC nylon wheel that increases the service life.
The purpose of this utility model is achieved in that integrated metal coil MC nylon wheel, comprise core wheel of making by metallic material and the outer ring of making by the MC nylon material, the core wheel center is provided with bearing mounting hole, bearing is installed in the bearing mounting hole, the periphery of core wheel is provided with some axial notches, the core wheel both sides also are provided with the flange of radial direction, and the outer ring one is watered and cast from outside the core wheel.
This device casts in the outer ring outside the core wheel, because the periphery of core wheel is provided with some axial notches, behind the casting outer ring, the MC nylon of outer ring will embed in the axial notch, when rotating, can not skid between outer ring and the core wheel; Because the core wheel both sides also are provided with the flange of radial direction, behind the casting outer ring, in the axial direction, can axial motion between outer ring and the core wheel; This device has been avoided simple MC nylon wheel and bearing direct contact and the wearing and tearing that produce, skidding; Overcome the MC nylon wheel because of self with the low harmful effect that bearing and whole mechanism are produced of gradient of temperature, loosening or move about in the hole as bearing; Stablized bearing, avoided it to rock and the vibration that produces, its transmission accuracy height can improve the operation life of whole mechanism.In the guide assembly that this device can be used for using in the mechanical fields such as elevator, elevator machinery.
For making things convenient for the installation of bearing, can adopt following structure, one: the bearing mounting hole of described core wheel is that the middle part diameter is little, the stepped hole that the both sides diameter is big, and two bearings are fit into the bearing mounting hole from both sides respectively; Its two: described bearing mounting hole is isometrical hole, is provided with two grooves in isometrical hole, is provided with jump ring in the groove, and two bearings is fit into the bearing mounting hole from both sides respectively, and conflicts respectively on the jump ring end face; In this scheme, for strengthening load-carrying capacity, be provided with the isometrical core retainer plate of internal diameter and bearing inner ring hole between the two bearings, can bear bigger axial force.
