Abstract
A kind of tensioning wheel, including wheel (1), tensioner arm (2), the bearing (3) being fitted in wheel (1), one end of described tensioner arm (2) sets and is affixed equipped interior installation anchor ring (4) with bearing inner race (3.1) lower end surface, and one end of described tensioner arm (2) also sets up top mounting surface (5.1) and is affixed equipped outer installation bulge loop (5) with wheel inner ring (6) lower end surface.Tensioning wheel can be to being partly also carried out dust-proof treatment effectively to extend whole service life under wheel.
Description
Technical field
The utility model is related to tensioning wheel sealing and dustproof technical field.
Background technology
At present, relatively conventional tensioning wheel typically sets up separately in the top of its wheel and puts dust cap to play wheel in dust-proof work
With.And dust-proof treatment typically then is not carried out for part under wheel, the dust cap for causing the lower part of wheel bearing to carry
Upper accumulation dust, so as to influence the normal service life of tensioning wheel.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of to being partly also carried out dust-proof treatment under wheel with effective
Extend the tensioning wheel of whole service life.
Technical solution of the present utility model is to provide a kind of tensioning wheel, including wheel, tensioner arm, is fitted to wheel
In bearing, one end of described tensioner arm sets and is affixed equipped interior installation anchor ring with bearing inner race lower end surface, described
One end of tensioner arm also sets up top mounting surface and is affixed equipped outer installation bulge loop with wheel inner ring lower end surface.
The loss of weight annular groove of indent is set between described interior installation anchor ring and outer installation bulge loop.
Described interior installation anchor ring is directly vertical with the center flange of tensioner arm to be connected, and center flange can be to entering from center
The dust for entering plays further iris action.
Transition anchor ring is set between described interior installation anchor ring and loss of weight annular groove, and transition anchor ring can reduce interior installation after setting
The working (finishing) area of anchor ring.
Tensioning wheel of the present utility model, under the dual setting of interior installation anchor ring and outer installation bulge loop, can play to dust
Dual barrier is acted on, and be effectively prevent dust and is entered from wheel bottom, and guaranteeing role is served to tensioning wheel life-time dilatation.
Brief description of the drawings
Fig. 1 be tensioning wheel of the present utility model a kind of embodiment in tensioner arm, wheel, bearing it is equipped after structural representation
Figure.
Fig. 2 is tensioner arm, wheel, the exploded structural representation of bearing in Fig. 1.
As shown in the figure：1 wheel, 2 tensioner arms, 2.1 center flanges, 3 bearings, 3.1 bearing inner races install anchor ring, outside 5 in 4
Bulge loop, 5.1 top mounting surfaces, 6 wheel inner rings, 7 loss of weight annular grooves, 8 transition anchor rings are installed.
Specific embodiment
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings.
As illustrated, a kind of specific embodiment of tensioning wheel of the present utility model：Including wheel 1, tensioner arm 2, it is fitted to
Bearing 3 in wheel 1.One end of described tensioner arm 2 sets and is affixed equipped interior mounting ring with the lower end surface of bearing inner race 3.1
Face 4.One end of described tensioner arm 2 also sets up top mounting surface 5.1, and to be affixed equipped outer installation with the lower end surface of wheel inner ring 6 convex
Ring 5.
More specifically, in this embodiment, described bearing and wheel integrated injection molding.
In this embodiment, wherein the interior center flange 2.1 for installing anchor ring 4 and tensioner arm 2 is direct vertical is connected.
As the improvement project of the present embodiment, subtracting for indent is set between described interior installation anchor ring 4 and outer installation bulge loop 5
Weight annular groove 7.And also set up transition anchor ring 8 between described interior installation anchor ring 4 and loss of weight annular groove 7.
Tensioning wheel of the present utility model, using the lower surface and the lower surface of wheel inner ring of bearing itself inner ring, in tensioning
The mounting surface for mutually being mounted with above-mentioned lower surface and being matched is set on arm, dust-proof effect is played so as to mount matching by face face.
The dual setting of mounting surface, dust-proof effect highly significant.
