Abstract
The utility model relates to a kind of integral type roll wheel assembly.The utility model comprises: a metal roller outer ring; A plurality of balls, are located in described roller outer ring by ball retainer; One metal roller inner ring, is arranged in described roller outer ring, and makes a plurality of described balls between described roller outer ring and described roller inner ring; The outer ring outer wall of described roller is equipped with groove, is provided with the coating member that composite material is made in described groove.By the enforcement to technical solutions of the utility model, can obtain following technique effect: less number of components makes the raw MAT'L loss minimizings such as fabrication processing shortening, iron and steel, whole workpiece process consuming time less; Less number of components makes equipped Risk Reduction not in place, and has reduced Mismachining tolerance accumulation, thereby has improved the overall precision of roll wheel assembly.
Description
Technical field
The utility model relates to a kind of elevator parts, relates in particular to a kind of integral type roll wheel assembly.
Background technology
Elevator is a kind of vertical conveyor that electrical motor is power of take, and elevator conventionally dress is had case shape car, for tier building, takes advantage of people or carrying goods.Door strap is one of critical component in elevator device, and is installed on roll wheel assembly on door strap its crucial subassembly especially.The roll wheel assembly using on existing door strap is because parts are more, there is relatively more, the whole workpiece processing of the raw MAT'L loss such as length, the iron and steel defect such as large consuming time of fabrication processing, and the accumulation Mismachining tolerance that has equipped risk not in place between a plurality of parts and certainly exist.
Summary of the invention
For existing roll wheel assembly, close the problems referred to above that exist, the main purpose of the technical scheme that the utility model provides is: a kind of processing and good integral type roll wheel assembly of precision of being easy to is provided.
To achieve these goals, the utility model has adopted following technical scheme:
An integral type roll wheel assembly, wherein, comprising:
One metal roller outer ring;
A plurality of balls, are located in described roller outer ring by ball retainer;
One metal roller inner ring, is arranged in described roller outer ring, and makes a plurality of described balls between described roller outer ring and described roller inner ring;
The outer ring outer wall of described roller is equipped with groove, is provided with the coating member that composite material is made in described groove.
On the other hand of the present utility model, also comprise Step Shaft, described Step Shaft is arranged in described roller inner ring.
On the other hand of the present utility model, also comprise Step Shaft, described roller inner ring is mainly formed by a stepped portion of described Step Shaft.
On the other hand of the present utility model, described roller outer ring is made by bearing steel.
On the other hand of the present utility model, described composite material is polyurethane.
By the enforcement to technical solutions of the utility model, can obtain following technique effect:
1, less number of components makes the raw MAT'L loss minimizings such as fabrication processing shortening, iron and steel, whole workpiece process consuming time less;
2, less number of components makes equipped Risk Reduction not in place, and has reduced Mismachining tolerance accumulation, thereby has improved the overall precision of roll wheel assembly.
Accompanying drawing explanation
Fig. 1 is the cross-sectional view of integral type roll wheel assembly of the present utility model;
Fig. 2 is the cross-sectional view that the Step Shaft of integral type roll wheel assembly of the present utility model forms the embodiment of roller inner ring.
The specific embodiment
By specific embodiment, the technical solution of the utility model is described below, with the conflict free prerequisite of utility model object of the present utility model under, embodiment and the technical characterictic in embodiment hereinafter mentioned can combine mutually.
As shown in Figure 1-2, the utility model provides a kind of integral type roll wheel assembly, wherein, comprising:
One metal roller outer ring 1;
A plurality of balls 3, are located in roller outer ring 1 by ball retainer;
One metal roller inner ring 2, is arranged in roller outer ring 1, and makes a plurality of balls 3 between roller outer ring 1 and roller inner ring 2;
The outer wall of roller outer ring 1 is equipped with groove, is provided with the coating member 4 that composite material is made in groove.
Existing roll wheel assembly is riveted on a deep groove ball bearing in one roller outer ring conventionally, because adopting the round steel pipe of carbon structural steel material conventionally, roller outer ring manufacture craft carries out turning, ground finish, to meet the matching requirements of subsequent deep trench ball-bearing casing, and follow-up roller outer ring also needs to carry out corresponding pressure riveted joint assembling with deep groove ball bearing, relatively the raw MAT'L loss such as length, iron and steel is more, whole workpiece processing is consuming time greatly to cause technological process.
And, when follow-up roller outer ring and deep groove ball bearing pressure riveted joint assembling, there is certain risk equipped not in place and the accumulation Mismachining tolerance certainly existing, while causing roller real work, there is relatively large coaxiality error, run-out error in desired deep groove ball bearing inner ring and roller outer ring.
In the technical solution adopted in the utility model, deep groove ball bearing outer ring in conventional roll wheel assembly, roller outer ring are united two into one, minimizing in number of parts has brought the effective minimizing in operation, and the processing homogeneous phase of the processing of former roller outer ring its inner ring of part, its inner ring of former deep groove ball bearing outer ring should be cancelled; And the pressure staking process of original deep groove ball bearing assembly and roller outer ring is cancelled.
Because the structure of integral type is cancelled the pressure staking process of original bearing assembly and roller outer ring, corresponding, assembling equivalent risk not in place, assembly accumulation error that its original staking process brings have all obtained good elimination.
In a kind of embodiment of the present utility model, also comprise Step Shaft 5, Step Shaft 5 is arranged at (this embodiment is not in shown in figure) in roller inner ring 2.Step Shaft 5 is for being connected to roll wheel assembly the door strap 6 of elevator.
In a kind of preferably embodiment, as shown in Figure 2, roller inner ring 2 can be mainly formed by a stepped portion of Step Shaft 5.Thereby further deep groove ball bearing inner ring 2 of the prior art is cancelled, further reduced operation, and further improved overall precision.
In a kind of embodiment of the present utility model, roller outer ring 1 can be made by bearing steel.
In a kind of embodiment of the present utility model, composite material is polyurethane.
The above embodiments are only that part of the present utility model embodies; can not contain of the present utility model whole; on the basis of above-described embodiment and accompanying drawing; those skilled in the art can obtain more embodiment under the prerequisite of not paying creative work, so these are not paid the embodiment obtaining under the prerequisite of creative work and all should be included in protection domain of the present utility model.
