Abstract
The utility model discloses a belt tensionern of taper connection type automobile, which consists of a shell, a tension arm, a torsion spring, a loop strain clamp, a spring sleeve, a sliding bearing, a front wheel, a pulley, a tension wheel, a bearing, a torsion bolt and a dust cap. The utility model is characterized in that: the tension arm is a cone body that is sleeved by a sliding bearing. The outer wall of the cone hole of the shell is sleeved joint with the spring sleeve, the loop strain clamp and the torsion spring. Support tips on both ends of the torsion spring are inserted respectively in the shell and in a positioning hole on sidewall of the tension arm. The tension arm can produce variational damping force when twisting so as to maintain the tension of the tension wheel to the belt within a fixed range. The utility model has the advantages of compact structure, stable performance and long service life, and is convenient to be assembled and positioned.
Description
The utility model belongs to a kind of improvement of automobile belt stretcher.
The automobile belt stretcher is an important component part of automotive engine, it mainly acts on is the drive belt of devices such as tensioning automobile engine crankshaft belt pulley driving automobile water pump, power assistance pump for steering, electrical generator, air conditioning pump, so that devices such as auto pump, power assistance pump for steering, electrical generator, air conditioning pump keep normal operation.Though traditional automobile fixed type tensioner is simple in structure, and following shortcoming is arranged:
1, fixed type tensioner installation site is fixed, and the tensile force of belt is depended on the installation site of tensioner, so have relatively high expectations in the installation site.
The tension wheel control position was fixed when 2, the fixed type tensioner was worked, automobile when starting, speedup, reduction of speed, turning because change in torque, the belt girth can produce elongation and shorten, this will produce the variation to belt tension of tension wheel neck bearing bearing capacity and tensioner, influences the service life of tension wheel and belt and correlated parts thereof.
3, after belt used a period of time, elongation gradually, and the fixed type tensioner can automatically regulating so tension wheel will reduce the tensile force of belt, produced skidding.
The purpose of this utility model provide a kind of can be in vehicle traveling process tension wheel automatically regulating position, tensile force is in the constant scope, and easy for installation, the tapering coupling type automatic belt tightener device of long service life.
The utility model comprises the bearing (10) and the tension wheel (9) of housing (1), tensioner arm (2), tensioner arm (2) lower end.It in the tensioner arm (2) cone (2 '), tapered sleeve type plain bearing (6) is arranged on the cone (2 '), protruding key in this plain bearing (6) taper hole is captiveed joint with tensioner arm (2) male cone (strobilus masculinus) positioning groove, taper hole bearing fit with housing (1), the taper hole outer wall of housing (1) is pocketed springs sleeve (5) successively, kink tension chuck (4) and torsion spring (3), the fixing feet at torsion spring (3) two ends is inserted into respectively in the knock hole of housing (1) and tensioner arm (2) sidewall.Housing (1) passes through tapering mode pulley (8) and the connection of front-wheel (7) riveted in the die cavity of housing (1) right-hand member with tensioner arm (2), and tensioner arm (2) and housing (1) can be turned round automatically.The outside of bearing (10) is provided with through reversing the fixing cover of dust (12) of screw (11).
Be provided with torsion spring (3), kink tension chuck (4) and spring spool (5) in the utility model housing, tension wheel (9) can be changed and the automatically regulating position with strap length when running car, tensile force is in the constant scope, can guarantee tensioner and relevant apparatus normal operation and effective service life of improving them.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model front view.
Accompanying drawing 3 is that the L of Fig. 2 is to view.
Accompanying drawing 4 is that the K of Fig. 2 is to view.
Further describe the utility model below in conjunction with accompanying drawing 1,2 and embodiment.
The utility model is fixed on the engine body when using, housing (1) and the available fine aluminum alloy casting of tensioner arm (2), and tensioner arm (2) is an integral body with cone (2 '), the outer wall of cone (2 ') axially has a positioning groove at least.
Plain bearing (6) can be made of modified nylon materials, and it is by protruding key in the internal taper hole and the positioning groove heavy keying fit on the cone (2 '), and its male cone (strobilus masculinus) and housing (1) internal taper hole bearing fit has reduced the contact wear between housing (1) and the tensioner arm (2).
Pulley (8) and front-wheel (7) are arranged in the die cavity of housing (1) right-hand member.Pulley (8) can be made by modification of nylon, to reduce the wearing and tearing between part.The right-hand member of cone (2 ') and front-wheel (7) riveted joint, housing (1) and tensioner arm (2) have been realized reliable connection by the tapering mode, the tension wheel (9) that makes tensioner arm (2) arm end is realized the automatically regulating of tension wheel (9) position with the revolution of (00) axial line.
Torsion spring (3) is the high strength torsion spring, and the fixing feet at its two ends is installed in respectively in the knock hole of housing (1) and tensioner arm (2) sidewall (referring to accompanying drawing 3,4), makes it be in powerful twisting states.The torsion of torsion spring (3) inwardly shrinks spring inside diameter, produces and holds power tightly, and the power of holding tightly is strained chuck (4) through kink, makes spring spool (5) hold the friction force that the face of cylinder on the housing (1) changes tightly.Spring spool (5) adopts modification of nylon to make, and the friction force that tensioner arm (2) is produced when reversing forms the dumping force in the whole device, and dumping force changes with tensioner arm corner size, and tension wheel is remained within certain steady state value the tensile force of belt.
Claims (3)
1, tapering coupling type automobile automatic belt tightener device, comprise housing (1), tensioner arm (2), the bearing (10) of tensioner arm (2) lower end and tension wheel (9), it is characterized by in the tensioner arm (2) is a cone (2 '), tapered sleeve type plain bearing (6) is arranged on the cone (2 '), protruding key in this plain bearing (6) internal taper hole is captiveed joint with tensioner arm (2) male cone (strobilus masculinus) positioning groove, taper hole bearing fit with housing (1), the taper hole outer wall of housing (1) is pocketed springs sleeve (5) successively, kink tension chuck (4) and torsion spring (3), the fixing feet at torsion spring (3) two ends is inserted into respectively in the knock hole of housing (1) and tensioner arm (2) sidewall.
2, by the described tapering coupling type of claim 1 automobile automatic belt tightener device, it is characterized by housing (1) and pass through tapering mode pulley (8) and the connection of front-wheel (7) riveted in the die cavity of housing (1) right-hand member, tensioner arm (2) and housing (1) can be turned round automatically with tensioner arm (2).
