Technical field
The utility model relates to mechanical tensioner, more relates to the mechanical tensioner of the chain transmission system for internal-combustion engine.
Background technique
In the chain transmission system of internal-combustion engine, mechanical tensioner is in order to tension chain thus reduce the vibration of chain in internal combustion engine operation process.Shown in Fig. 1 and Fig. 2 is a kind of mechanical tensioner 1 of present application, it spring element 12 comprising guide chain plate 10 and be arranged on guide chain plate 10.Guide chain plate 10 has the main body portion of tabular, the tensioned portion 103 being positioned at main body portion side and the assembly department 102 be spaced apart with tensioned portion 103.Spring element 12 is arranged on outside the assembly department 102 on guide chain plate 10, and it has first end 121 and the second end 122.Described the second end 122 is fixed on a pin that internal-combustion engine is arranged, described first end 121 rely on the clamping part 101 that the main body portion of guide chain plate 10 is arranged fix.Described clamping part 101 is provided separately with described tensioned portion 103 and towards described tensioned portion 103, forms one between the two and install gap in order to install the first end 121 of described spring element 12.
In the working procedure of mechanical tensioner 1, described tensioned portion 103 is resisted against on chain in order to provide tension force.Spring element 12 is in tensioning state, and the first end 121 of spring element 12 is directly resisted against tensioned portion 103 towards on the side of assembly department 103.Produce because chain transmission system has vibration in the course of the work, these vibration passing depart from clamping part 101 to causing the first end 121 of spring element 12 during mechanical tensioner 1 from described installation gap, and this will directly cause the inefficacy of mechanical tensioner 1.
Therefore, need to provide a kind of new mechanical tensioner to solve this technical problem.
Model utility content
Therefore, the purpose of this utility model is to provide a kind of mechanical tensioner of improvement, and it can prevent the clamping part of spring element self-conductance carrier bar from departing from.
For solving the problem, the utility model provides a kind of mechanical tensioner, it spring element comprising guide chain plate and be arranged on guide chain plate, the assembly department that described guide chain plate has main body portion, is positioned at the tensioned portion of main body portion side and is spaced apart with described tensioned portion, described spring element is sleeved on described assembly department, and it has first end and the second end.The first end of described spring element relies on the clamping part be arranged in described tensioned portion to fix with the locating slot be arranged on described main body portion.
Compared with prior art, the technical solution of the utility model has the following advantages: the first end of described spring element relies on the clamping part be arranged in described tensioned portion to fix with the locating slot be arranged on described main body portion, and spring element can be avoided like this in mechanical tensioner working procedure to depart from guide chain plate.

Embodiment
As shown in Figures 3 to 5, mechanical tensioner 2 of the present utility model comprises guide chain plate 20 and is arranged on the spring element 30 on guide chain plate 20.Guide chain plate 20 has the main body portion 200 in tabular, the tensioned portion 203 being positioned at main body portion 200 side and the assembly department 202 be spaced apart with tensioned portion 203.Tensioned portion 203 is fan-shaped in what protrude, has in order to the tensioning face 2031 against chain outside it, and the external frame in this tensioning face 2031 is that cambered surface is arranged.Tensioned portion 203, being provided with the first side 2032 in the face of assembly department 202 side, is formed with clamping part 201 in the first side 2032 near the outside projection in main body portion 200 place.Clamping part 201 has plane of inclination 2011, and when spring element 30 is installed on assembly department 202, guide function can be played in this plane of inclination 2011.Assembly department 202 is the cylindric of hollow, and its hollow space is in order to install locating stud thus to be fixed on internal-combustion engine by whole mechanical tensioner 2.The position that main body portion 200 is combining near tensioning face 2031 and the first side 2032 is provided with locating slot 204, and this locating slot 204 runs through main body portion 200.
Spring element 30 is torque spring, and it has first end 301 and the second end 302.The second end 302 extends the outside of guide chain plate 20, and in the mounted state, described the second end 302 is fixed on a pin that internal-combustion engine is arranged mechanical tensioner 2.The first end 301 of spring element 30 has kink 3011 at end, and this kink 3011 is fixed in the locating slot 204 on guide chain plate 20 after spring element 30 is mounted to guide chain plate 20.
When spring element 30 is installed on guide carrier bar 20, first the kink 3011 of the first end 301 of spring element 30 is aimed at the locating slot 204 on guide chain plate 20, then the main part of spring element 30 is sleeved on the assembly department 202 on guide chain plate 20, and then press the first end 301 of spring element 30, allow it cross the clamping part 201 that the first side 2032 of tensioned portion 203 is arranged.Guide function is played in the plane of inclination 2011 that clamping part 201 is arranged in the process of first end 301 pressing downwards of spring element 30.Mechanical tensioner 2 in a tensioned state, the second end 302 of spring element 30 is along clockwise movement and be fixed on pin that internal-combustion engine is arranged, and the first side 2032 that at this moment first end 301 of spring element 30 is resisted against tensioned portion 203 provides moment of torsion.Locating slot 204 can prevent the first end 301 of spring element 30 from going up the main body portion 200 of disengaging guide chain plate 20 in the clockwise direction or counterclockwise.First end 301 due to spring element 30 is positioned at the below of clamping part 201, and spring element 30 in a tensioned state time, the first end 301 of spring element 30 can be resisted against on the first side 2032 of tensioned portion 203, even if the vibration passing that chain transmission system produces is to mechanical tensioner 2, the first end 301 of spring element 30 also only can move in the vertical direction, and at this moment clamping part 201 can prevent it from departing from the main body portion 200 of guide chain plate 20.
Although the utility model discloses as above, the utility model is not defined in this.Any those skilled in the art, not departing from spirit and scope of the present utility model, all can make various changes or modifications, and therefore protection domain of the present utility model should be as the criterion with claim limited range.
