Abstract

The utility model is in order to disclose a kind of escalator handrail aluminium core idler pulley wheel, and the wheel rim and bearing being mainly made up of aluminium core, nylon material are constituted；Wheel rim is set on the outer circumference surface of aluminium core；Have in aluminium core and be provided with a circle groove on the hole wall in the middle part of the through hole that an appearance roller bearing is passed through, aluminium core；Bearing is located in groove；Four T-shaped holes are provided with the cell wall of groove, this four T-shaped holes make angularly circumference array around the axle center of aluminium core；A T-shaped nail is fitted with each T-shaped hole；The insertion end of T-shaped nail can tightly link together wheel rim with aluminium core from being passed on the outer circumference surface of aluminium core and being inserted in wheel rim, peeled off even if wheel rim is dry and cracked from aluminium core, T-shaped nail can also limit wheel rim in displacement axially and radially, it is ensured that the operation stability of handrail.

Description

Escalator handrail aluminium core idler pulley wheel

Technical field

The utility model is related to elevator accessory technical field, in particular to escalator handrail aluminium core idler pulley wheel.

Background technology

It is to be run using friction pulley with handrail interband frictional force drives handrail mostly in commercial escalator.It is used to Form that cornerite between handrail and friction pulley and being run to handrail play the guiding role is upper and lower idler pulley wheel.Idler pulley wheel is relative to rub The depth of parallelism for wiping wheel decides that can it decide handrail lip and friction pulley by handrail by correct orientation guiding friction pulley Whether side, which produces, is mutually wiped and damages handrail.

Aluminium core idler pulley wheel is the more commonly used roller in elevator industry.The rubber layer of aluminium core outer layer covers can increase roller Wearability and bearing capacity, reduction operation noise；But, plastic cement is directly connected with aluminium core, easily occur it is dry and cracked, once it is dry and cracked, With aluminium core axial direction, diametrically displacement will occur for plastic cement, influence the operation stability of handrail.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of escalator handrail aluminium core idler pulley wheel, even if plastic cement Dry and cracked stripping occurs for layer, and with aluminium core axial direction, diametrically displacement will not also occur for plastic cement.

To reach above-mentioned purpose, the technical solution of the utility model is as follows：

Escalator handrail aluminium core idler pulley wheel, the wheel rim and bearing being mainly made up of aluminium core, nylon material is constituted；The wheel Snare is located on the outer circumference surface of the aluminium core；Have in the aluminium core in the middle part of the through hole that an appearance roller bearing is passed through, the aluminium core Hole wall on be provided with a circle groove；The bearing is located in the groove；

Four T-shaped holes are provided with the cell wall of the groove, this four T-shaped holes make angularly Circle-Array around the axle center of aluminium core Row；A T-shaped nail is fitted with each T-shaped hole；The insertion end of the T-shaped nail is worn from the outer circumference surface of the aluminium core Go out and be inserted in the wheel rim.

It is further that there are four circle deep-slotted chip breakers on the outer circumference surface of the aluminium core, the wheel rim correspondence deep-slotted chip breaker Place is convex with the arc being inserted in deep-slotted chip breaker, and the groove face of the deep-slotted chip breaker convex surface convex with the arc fits.

It is further that the aluminium core is respectively arranged a mounting groove for being used to install collar in the both sides of groove.

Compared with prior art, technological merit of the present utility model is：1. four T-shaped nails being inserted in wheel rim will can take turns Circle tightly links together with aluminium core, is peeled off even if wheel rim is dry and cracked from aluminium core, T-shaped nail can also limit wheel rim in axial direction and footpath To displacement, it is ensured that the operation stability of handrail；2. deep-slotted chip breaker preferably consolidates aluminium core and wheel rim with the convex cooperation of arc Surely link together, during roller is run, also protect aluminium core and the secure fit of wheel rim, prevent wheel rim Displacement, improves the service life of aluminium core.

Brief description of the drawings

, below will be to needed for embodiment description in order to illustrate more clearly of the technical scheme in the utility model embodiment The accompanying drawing to be used is briefly described.

Fig. 1 is the sectional view of the aluminium core idler pulley wheel disclosed in embodiment；

Fig. 2 is that the T-shaped disclosed in embodiment follows closely the schematic view of the mounting position in aluminium core；

Fig. 3 is the aluminium core sectional view disclosed in embodiment；

Fig. 4 is the enlarged diagram at A in Fig. 1.

Embodiment

Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is carried out Clearly and completely describe.

The present embodiment is referring to accompanying drawing 1-4.

Escalator handrail aluminium core idler pulley wheel, the wheel rim 2 and bearing 3 being mainly made up of aluminium core 1, nylon material is constituted；Wheel Snare is located on the outer circumference surface of aluminium core；Have in aluminium core and set on the hole wall in the middle part of the through hole 4 that an appearance roller bearing is passed through, aluminium core There is a circle groove 5；Bearing is located in groove.Four T-shaped holes 6 are provided with the cell wall of groove, axle of this four T-shaped holes around aluminium core The heart makees angularly circumference array；A T-shaped nail 7 is fitted with each T-shaped hole；Excircle of the insertion end of T-shaped nail from aluminium core Pass and be inserted in wheel rim on face, so wheel rim can tightly be linked together with aluminium core, even if wheel rim is done from aluminium core Stripping is split, T-shaped nail can also limit wheel rim in displacement axially and radially, it is ensured that the operation stability of handrail.

Having on the outer circumference surface of aluminium core at four circle deep-slotted chip breakers 8, wheel rim correspondence deep-slotted chip breaker has the arc being inserted in deep-slotted chip breaker Shape convex 9, the convex surface that the groove face of deep-slotted chip breaker is convex with arc fits.Deep-slotted chip breaker is with the convex cooperation of arc preferably by aluminium core and wheel rim It is fixed together, during roller is run, also protects aluminium core and the secure fit of wheel rim, prevent wheel rim from sending out Raw displacement, improves the service life of aluminium core.

It is further that aluminium core is respectively arranged a mounting groove 10 for being used to install collar in the both sides of groove.

A variety of modifications to these embodiments will be apparent for those skilled in the art, herein Defined General Principle can be real in other embodiments in the case where not departing from spirit or scope of the present utility model It is existing.Therefore, the utility model is not intended to be limited to the embodiments shown herein, and be to fit to it is disclosed herein The principle most wide scope consistent with features of novelty.
