Abstract
The utility model discloses a double-should type rubber apron wheel driving wheel, comprising a rubber apron wheel, an apron wheel iron core and a driving gear wheel. The two sides of the driving gear wheel are provided with a supporting piece for supporting the rubber apron wheel. An outer cylinder face of the supporting piece and a basic circle of the driving gear wheel are in the same axis. The utility model improves the forced condition of the apron wheel and the driving wheel, eliminates the apron wheel linear speed fluctuation and reduces the early abrasion of the apron wheel iron core and the driving gear wheel.
Description
Technical field
The utility model relates to a kind of caterpillar drive.
Background technology
Traditional rubber belt track drive wheel is the one chip zigzag structure, and this mechanism has continued to use the drive mechanism of metal track, and its advantage is simple in structure, easy to make, but shortcoming also clearly, that is:
1. the linear velocity of crawler belt can produce fluctuation in transmitting movement, has increased the additional impact of movement parts such as gear, axle, and the further speed-raising of continuously tracked vehicle is restricted.
Since bogie wheel, guide wheel and drive wheel not on same transmission cross section, the stressing conditions of rubber belt track inner structure worsens, and is the major cause that produces improper mill inefficacy of rubber belt track and drive wheel infantile failure.
Summary of the invention
The purpose of this utility model is: a kind of both shoulders formula rubber belt track drive wheel is provided, respectively increase a slice supporting slice in the drive wheel two sides exactly, improve the stressing conditions of crawler belt and drive wheel, eliminate the fluctuation of crawler belt linear velocity, reduce the premature wear of crawler belt iron core and driven wheel.
The technical solution of the utility model is: a kind of both shoulders formula rubber belt track drive wheel, comprise rubber belt track, crawler belt iron core, driven wheel, the both sides of described driven wheel are provided with the supporting slice of lifting rubber belt track, and the external cylindrical surface of this supporting slice is coaxial with the basic circle of driven wheel.
The further technical scheme of the utility model is: a kind of both shoulders formula rubber belt track drive wheel, comprise rubber belt track, crawler belt iron core, driven wheel, the both sides of described driven wheel are provided with the supporting slice of lifting rubber belt track, and the external cylindrical surface of this supporting slice is coaxial with the basic circle of driven wheel; The supporting slice of described driven wheel both sides is symmetrical arranged, and is ψ shape with cross section after driven wheel combines.
Two supporting slices in the technique scheme are fixed on the both sides of driven wheel with pin, perhaps with the moulding of driven wheel integral production.
The utility model has the advantages that:
1. the utility model makes the crawler belt iron core contact stressed with driven wheel tooth root arc surface list cross section, become three cross sections and prop up holding capacity jointly, the stressing conditions of rubber belt track and driven wheel is greatly improved, the transmission of moment of torsion also becomes flank and the coefficient moment of torsion transfer mode of bogie wheel friction by the flank transmission, the contact stress of flank reduces, and the premature wear situation will be improved greatly.
2. because the utility model is first before the crawler belt iron core contact with the blade teeth root contacts with supporting slice, make crawler belt change the process of circular motion over to from straight-line motion, become smoothly soft, the fluctuation disappearance of crawler belt linear velocity.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Wherein: 1 rubber belt track; 2 crawler belt iron cores; 3 driven wheels; 4 supporting slices; 5 pins.
The specific embodiment
Embodiment: as shown in Figure 1, a kind of both shoulders formula rubber belt track drive wheel, comprise rubber belt track (1), crawler belt iron core (2), driven wheel (3), the both sides of described driven wheel (3) are provided with the supporting slice (4) of lifting rubber belt track (1), supporting slice (4) is symmetrical arranged, be ψ shape with the cross section after driven wheel (3) combines, the external cylindrical surface of supporting slice (4) is coaxial with the basic circle of driven wheel (3).Two supporting slices (4) are fixed on the both sides of driven wheel (3) with pin (5), also can with driven wheel (3) integral production moulding.
The utility model makes the single cross section of crawler belt iron core (2) and driven wheel (3) tooth root circle cambered surface contact stressed, become three cross sections and prop up holding capacity jointly, the stressing conditions of rubber belt track (1) and driven wheel (3) is greatly improved, the transmission of moment of torsion also becomes flank and the coefficient moment of torsion transfer mode of bogie wheel friction by the flank transmission, the contact stress of flank reduces, and the premature wear situation will be improved greatly.
Because the utility model is after driven wheel (3) both sides have increased supporting slice (4), before being contacted with the blade teeth root, crawler belt iron core (2) contacts with supporting slice (4) earlier, make rubber belt track (1) change the process of circular motion over to from straight-line motion, become smoothly soft, the fluctuation of crawler belt linear velocity disappears.
The utility model can be applicable to field machine, construction machinery and equipment and the military machinery of rubber caterpillar type.
Claims (4)
1. both shoulders formula rubber belt track drive wheel, comprise rubber belt track (1), crawler belt iron core (2), driven wheel (3), it is characterized in that: the both sides of described driven wheel (3) are provided with the supporting slice (4) of lifting rubber belt track (1), and the external cylindrical surface of this supporting slice (4) is coaxial with the basic circle of driven wheel (3).
2. both shoulders formula rubber belt track drive wheel according to claim 1 is characterized in that: the supporting slice (4) of described driven wheel (3) both sides is symmetrical arranged, and is ψ shape with cross section after driven wheel (3) combines.
3. both shoulders formula rubber belt track drive wheel according to claim 1 and 2 is characterized in that: described two supporting slices (4) are fixed on the both sides of driven wheel (3) with pin (5).
4. both shoulders formula rubber belt track drive wheel according to claim 1 and 2 is characterized in that: described two supporting slices (4) and driven wheel (3) integral production moulding.
