Abstract
Drive device for a traction mechanism, a rail (1) for a traction mechanism (2), having a carrier (3) and a sliding layer (4) arranged on the carrier (3), wherein the sliding layer (4) is arranged on a plane (5) of the carrier (3) facing the traction mechanism (2), both the carrier (3) and the sliding layer (4) are made of plastic and are connected to one another in a material-fit manner, wherein the material-fit connection (6) is produced by means of laser transmission welding.
Description
Technical field
The present invention relates to the haulage gear slide rail of traction mechanism drive, this slide rail has
Seat and the sliding layer that is arranged on this bearing, the most not only bearing but also sliding layer all material fit
(stoffschl ü ssig) be connected to each other.
Background technology
From the slide rail of mentioned kind known in document EP 1 338 828 A1.Slide rail is used in the publication
Pressure casting method manufactures.Not only bearing, and sliding layer is made the most together in a two-piece type mold
Make.It is first turned on the first sprue-way within this mold, so that support material can flow into.
After of short duration cooling stage, mold is the most drawn apart from one another so that the second sprue-way is opened.According to phase
, there is a free space along bearing side in the mold pulled open mutually.Therefore, of short duration cold
But after the stage, the material of sliding layer injects the space of release by the second sprue-way.Due to this two
Plant material and there is identical fusing point, therefore the material of gliding mass is connected with the material of bearing.With this side
The slide rail of formula manufacture needs multiple working procedure and cooling stage.Further, it is necessary to be that the two component (props up
Seat and sliding layer) use identical plastics, or at least use the plastics with identical fusing point,
To prevent the crack in articulamentum during cooling stage.
Summary of the invention
The task of the present invention is, it is provided that a kind of with low cost, simple and add with few operation
The slide rail of work.
According to the present invention, task is solved by following manner, i.e. this sliding layer is saturating by means of laser
Penetrate welding material to be arranged in ordinatedly on bearing.
By laser transmission welding known in DE 100 04 538 A1 of applicant BLZ, thus here
As long as making brief elaboration:
Major part thermoplastic (as long as they are not furnished with absorbent filler) swashs for specific
Optical wavelength all has high transparency.This makes the transmission welding of thermoplastic plastics be possibly realized.
Here, the parts to laser beam transmission are placed on another with moulding that absorbent material is filled
On material parts, and welded by the irradiation of laser beam.This laser beam transparent top saturating
The cover layer penetrated, and arrive on the absorbability plastic parts of bottom.The latter is melted in surface,
The fused mass being consequently formed extends, and superincumbent joint partner at infiltration.Passed by heat
Leading and heat radiation, transmission layer is melted equally.Then, the borderline region between described two-layer
In, there is hot transposition process in strand, and therefore constitutes melting welding connection.Here, can pass through
Laser beam produces weld seam to the relative motion of workpiece.
The principal advantages of the laser transmission welding of thermoplastic plastics is that processing speed is high, this be because of
It is transported to joint place with the light velocity for engaging the melted required energy of partner.At this moment, only produce
Raw little fusing volume, this brings the few delay engaging partner.Particularly with high-power two poles
Pipe laser instrument provides compact and with low cost lasing light emitter, and this brings less operation and safeguards into
This.
It is that bearing and sliding layer can have different according to the special benefits of the slide rail of the present invention
Material, such as, bearing PA66 or the PA46 with GF35 (glass fiber reinforcement), and
The sliding layer plastics mixed with lubricating additive.Accordingly, can be for the function selecting of each component
Best plastics on cost, and without making each joint partner consistent.When the present invention embodies,
The suggestion cheap strip material of use cost is as sliding layer.Therefore have only to welding process it
Before or cut off strip material afterwards.Accordingly, because processing speed is high during transmission welding, can make
Make the slide rail of high number of packages, the most integrally implement and meet bearing simultaneously and sliding layer
Functional requirement.This according to the slide rail of the present invention in save extra installment work, such as exist
Press from both sides or plug sliding layer on guide rail, and this is necessary in two-piece type slide rail.Equally, save
Go the extrusion process manufacturing single type slide rail utilizing different plastics of high consumption.
Accompanying drawing explanation
The present invention is shown in fig 1 and 2, is described in detail subsequently.
Illustrate:
The side view of Fig. 1 slide rail；With
The schematic section diagram of Fig. 2 slide rail.
Detailed description of the invention
Fig. 1 and 2 illustrates the slide rail 1 of the haulage gear 2 of traction mechanism drive in other words
The cross section of this slide rail is shown at Fig. 2.Slide rail 1 has bearing 3 and is arranged on bearing 3
Sliding layer 4.Sliding layer 4 is arranged in the plane 5 towards haulage gear 2 of bearing 3.Slide
Layer 4 and bearing 3 are connected to each other by the connection 6 of material fit.The connection 6 of this material fit
Manufacture in plane 5 by means of laser transmission welding.Here, laser beam 7 penetrates opaque
Sliding layer 4 and arriving at absorbability bearing 3, or arrive bearing towards sliding layer 4 times
In the plane 5 of side.The latter is melted in surface, and the fused mass being consequently formed extends and soaks
The downside of profit sliding layer 4.By laser beam 7, the relative motion of slide rail 1 is produced weld seam, enter
And thus produce the connection 6 of the material fit between bearing 3 and sliding layer 4.
