Abstract
A metal wheel sleeved with high-strength MC nylon relates to a transmission component used in the mechanical field of elevators, cranes and the like, and particularly relates to a high-speed transmission wheel. The metal wheel comprises a wheel core made of metal materials and a nylon outer ring made of MC nylon materials, the wheel core is concentrically disposed inside the nylon outer ring, a bearing mounting hole is disposed at the center of the wheel core and is a constant-diameter hole, at least one bearing is mounted inside the bearing mounting hole, two outer ring grooves are radially disposed inside the nylon outer ring, two first axial movement preventive devices are respectively arranged inside the two outer ring grooves and respectively disposed on two sides of the wheel core, and a recess and a boss which match with each other are disposed between the wheel core and the nylon outer ring. During rotating, the metal wheel can not skid due to the recess and the boss which match with each other between the nylon outer ring and the wheel core. Besides, the metal wheel stabilizes the bearings, avoids vibrating due to shaking of the bearings, is high in transmission precision, and can increase integral operation speed and prolong service life.
Description
Technical field
The utility model relates to the transmitting assemblies that uses in the mechanical fields such as elevator, Hoisting Machinery, particularly a kind of high speed drive wheel.
Background technique
In elevator, Hoisting Machinery industry, existing a large amount of MC nylon materials 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 working life of influence transmission in the hole as bearing.
The model utility content
The purpose of this utility model provides a kind of high-strength MC nylon wheel of metallic sheath that can ensure MC nylon wheel transmission precision, satisfy at a high speed, increase the service life.
The purpose of this utility model is achieved in that the high-strength MC nylon wheel of metallic sheath, comprise core wheel of making by metallic material and the nylon outer ring of making by the MC nylon material, described core wheel is arranged in the nylon outer ring with one heart, the center of core wheel is provided with bearing mounting hole, described bearing mounting hole is isometrical hole, and at least one bearing is installed in the bearing mounting hole; Two outer ring grooves radially are set in the described nylon outer ring, the first anti-axial motion device is set respectively in two outer ring grooves, described two first anti-axial motion devices are separately positioned on the both sides of core wheel, setting matches between described core wheel and the nylon outer ring concavo-convex.
This device carries out spun casting with metallic sheath and nylon outer ring with the form of integral body and forms, because the periphery of core wheel is provided with rule or irregular groove, in the spun casting process, fill this groove by nylon material, to reach fixing purpose, when rotating, can not skid between nylon outer ring and the core wheel.This device also can be packed metallic sheath in the nylon wheel center hole into the form of combination, because the periphery of core wheel is provided with groove or boss, the MC nylon of nylon outer ring is provided with boss or groove, and core wheel and nylon outer ring are tightened mutually, when rotating, can not skid between nylon outer ring and the core wheel.Because the core wheel both sides axial motion device of also having set up defences, in the axial direction, can axial motion between nylon outer ring and the core wheel; This device has avoided simple MC nylon wheel directly to contact with bearing 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, under at fast state, bearing is loosening or move about in the hole; Stablized bearing, avoided it to rock and the vibration that produces, its transmission accuracy height can improve the motion speed and the life-span of whole mechanism.In the transmitting assemblies that this device can be used for using in the mechanical fields such as elevator, Hoisting Machinery.
Described bearing mounting hole is isometrical hole, two core wheel grooves radially are set in described core wheel, the second anti-axial motion device is set respectively in two core wheel grooves, and described each the first anti-axial motion device and the second anti-axial motion device are separately positioned on corresponding bearing both sides.
The described first anti-axial motion device is a jump ring.
The described second anti-axial motion device is a jump ring.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is an another kind of structural representation of the present utility model.
Wherein, 1 nylon outer ring, 2 core wheels, 3 bearings, 4 bearing mounting holes, 5 grooves, 6 boss, 7 first jump rings, 8 outer ring grooves, 9 second jump rings, 10 core wheel grooves.
Embodiment
As shown in Figure 1, for metal inlaying in a kind of disjunctor overlaps high-strength MC nylon wheel, the core wheel 2 that metallic material is made and carry out spun casting with the form of integral body by the nylon outer ring 1 that the MC nylon material is made, core wheel 2 is arranged in the nylon outer ring 1 with one heart, core wheel 2 outer rule or the irregular grooves 5 of being provided with, the boss 6 that is formed by nylon material in the spun casting process is filled this groove 5.The center of core wheel 2 is provided with bearing mounting hole 4, and bearing mounting hole 4 is isometrical hole, and two bearings 3 are installed in the bearing mounting hole 4.Radially be provided with in the nylon outer ring 1 in 8, two outer ring grooves 8 of two outer ring grooves first jump ring 7 is set respectively.Radially be provided with in core wheel 2 in 10, two core wheel grooves 10 of two core wheel grooves second jump ring 9 is set respectively, each first jump ring 7 and second jump ring 9 are separately positioned on corresponding bearing 3 both sides.
As shown in Figure 2, for combined metal overlaps high-strength MC nylon wheel, comprise the core wheel 2 made by metallic material ' and the nylon outer ring 1 of making by the MC nylon material ', core wheel 2 ' be arranged on one heart nylon outer ring 1 ' in, core wheel 2 ' be provided with outward groove 5 ', the boss 6 of nylon outer ring 1 ' interior setting and groove 5 ' match ', this device is packed metallic sheath in the nylon wheel center hole into the form of combination.Core wheel 2 ' the center be provided with bearing mounting hole 4 ', bearing mounting hole 4 ' be isometrical hole, bearing mounting hole 4 ' in be equipped with two bearings 3 '.Nylon outer ring 1 ' interior radially be provided with two outer ring grooves 8 ', two outer ring grooves 8 ' interior be provided with respectively first jump ring 7 '.Core wheel 2 ' interior radially be provided with two core wheel grooves 10 ', two core wheel grooves 10 ' interior be provided with respectively second jump ring 9 ', the corresponding bearing 3 ' both sides of each first jump ring 7 ' and second jump ring 9 ' be separately positioned on.
