Abstract
The utility model discloses a column connection type automobile automatic belt stretcher, which comprises a casing body, a stretching arm, a torsional spring, a kink stretching chuck, a spring bushing, a sliding bearing, a locating axle, a front wheel, a sliding wheel, a stretching pulley, a bearing, a torsional screw, and a dust cover, etc. The utility model is characterized in that the stretching arm and the casing body adopt the column small clearance matching type riveting way through the locating axle and three layers of compound sliding bearings, making the stretching pulley at the end of the stretching arm revolve with the (OO) axial line, and thereby realize the automatic adjusting of the position of the stretching pulley. When the stretcher of the utility model works, the radial bearing capacity is large, the utility model eliminates the inclination phenomena of the stretching arm and the stretching pulley, without the stretching pulley deviation being away from the belt center, reduces vibration with stable work, and prolongs the service life.
Description
The utility model belongs to a kind of improvement that is used for the automatic belt tightener device of motor car engine.
The main effect of automobile automatic belt tightener device is the drivign belt of devices such as tensioning automobile engine crankshaft belt pulley driving automobile water pump, power assistance pump for steering, generator, air conditioning pump, so that devices such as auto pump, power assistance pump for steering, generator, air conditioning pump keep proper functioning.Existing tapering coupling type automobile belt tightener utilizes cone to connect, and its major defect is: during work, the tapering bind mode is the bearing capacity deficiency radially, cause the stretcher vibration big, Idle wheel tilts, and Idle wheel departs from the belt center, makes belt shortening in working life.
The purpose of this utility model provides a kind of working stability, and radially bearing capacity is big during Idle wheel work, the automobile automatic belt tightener device of long service life.Can reduce the matching gap between tension arms (2) and the housing (1), eliminate tension arms (2) and Idle wheel (10) and tilt to cause Idle wheel to depart from the belt center, reduce oscillation phenomenon.
The utility model comprises housing (1), tension arms (2), positioning shaft (7), is positioned at the Idle wheel (10) of tension arms (2) arm end, front-wheel (8) and pulley (9) in the bearing (11) and reverse screw (12), housing (1) right-hand member die cavity.The shaft hole inner wall that it is characterized by housing (1) is provided with the sliding bearing (6) that adopts the little Spielpassung of cylindrical hole with positioning shaft (7), outer wall is pocketed springs sleeve (5) successively, kink tension chuck (4) and torsion spring (3), fastening foot 3a, the 3b at torsion spring (3) two ends is inserted into respectively in the positioning hole 2 ' of housing (1) positioning hole 1 ' and tension arms (2) sidewall.Positioning shaft (7) left end and the riveted joint of tension arms (2) endoporus, right-hand member and front-wheel (8) riveted joint.Positioning shaft (7) adopts little Spielpassung with sliding bearing (6), and centering is reliable, and radially bearing capacity is big, and operating mode is stable, can effectively prevent the stressed inclination of Idle wheel, improves working life.
Accompanying drawing 1 is the utility model structural representation.
Accompanying drawing 2 is the utility model plan 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 drawings and Examples.
Referring to accompanying drawing 1, the endoporus of housing (1) is provided with sliding bearing (6), positioning shaft (7) make by High Strength Steel and the axis hole of housing of packing into (1) and tension arms (2) in, left end and tension arms (2) endoporus, right-hand member and front-wheel (8) riveted joint.Positioning shaft (7) and sliding bearing (6) are little Spielpassung, clump and make the Idle wheel (10) of tension arms (2) arm end realize the automatic adjusting of Idle wheel position with (OO) shaft axis revolution.Sliding bearing (6) is the 3-layer composite material bearing, and internal layer is the PTFE plastic layer, and the middle level is the steel plate layer, and skin is a copper alloy layer.The axis hole outer wall pocketed springs sleeve (5) of housing (1), the left end suit kink tension chuck (4) of spring spool (5), torsion spring (3) internal diameter is sleeved on the kink tension chuck (4), there is a sole 5 ' outer ring of spring spool [5], the fastening foot 3b of torsion spring (3) is pressed on the sole 5 ', and be inserted in the positioning hole 2 ', another fastening foot 3a of torsion spring (3) is inserted into the rhombus positioning hole 1 ' interior (referring to accompanying drawing 3,4) of housing [1] sidewall.Torsion spring (3) is the high strength torsion spring, and it is 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, the frictional force that the cylndrical surface that makes spring spool (5) hold housing (1) tightly changes.Spring spool (5) adopts modification of nylon to make, the frictional force that produces when reversing at tension arms (2) forms the damping force in the whole device, damping force is with the variation of tension arms corner size, Idle wheel is remained within certain steady state value the tension force of belt, and the position of the Idle wheel (10) of tension arms (2) arm end is regulated automatically.Housing (1) is provided with three positioning holes, so that fix with engine body.Be provided with nylon pulley (9) and metal front-wheel (8) in housing (1) the right-hand member die cavity, Idle wheel (10) is positioned at the lower end of tension arms (2), is made by high-strength abrasion-proof nylon, and passes through bearing (11) and reverse screw (12) and tension arms (2) connection.Bearing (11) outside is provided with dust cover (13).
Claims (3)
1, cylinder coupling type automatic belt tightener device comprises housing (1), tension arms (2), positioning shaft (7), be positioned at the Idle wheel (10) of tension arms (2) arm end, bearing (11) and reverse screw (12), front-wheel (8) and pulley (9) in housing (1) the right-hand member die cavity, the shaft hole inner wall that it is characterized by housing (1) is provided with the sliding bearing (6) that adopts cylindrical hole to cooperate with positioning shaft (7), outer wall is pocketed springs sleeve (5) successively, kink tension chuck (4) and torsion spring (3), the fastening foot 3a at torsion spring (3) two ends, 3b is inserted into respectively in the positioning hole 2 ' of housing (1) positioning hole 1 ' and tension arms (2) sidewall.Positioning shaft (7) left end and the riveted joint of tension arms (2) endoporus, right-hand member and front-wheel (8) riveted joint.
2,, it is characterized by between housing (1) tension arms (2) and adopt the little gap of cylindrical hole pattern to cooperate by positioning shaft (7) sliding bearing (6) by the described cylinder coupling type of claim 1 automatic belt tightener device.
