Description
Technical field
The utility model relates to the transmission parts on a kind of diesel engine, and in particular to a kind of sloth wheel gear.
Background technique
Sloth wheel gear is the gear for playing transmitting among two transmission gears not contacted with each other, while with the two teeth
Wheel engagement, for changing the rotation direction of driven gear, is allowed to identical as driving gear.Its effect, which only changes, to be turned to not
Transmission ratio, referred to as sloth wheel gear, also known as carrier gear can be changed.
Diesel engine is generally used for truck, on lorry, and diesel engine had been driven since the torque of output is bigger
Can be than more serious to the abrasion between gear in journey, especially sloth wheel gear will bear biggish torsion when transmitting torsion, then
In addition truck and lorry often overload and travel on concave-convex different road, sloth wheel gear is caused to bear the enormous impact of moment
Torsion is allowed to abrasion and the gap between other transmission gears increases, and influencing transmission efficiency, sloth wheel gear is easily damaged simultaneously.
Summary of the invention
To solve the above problems, avoiding gap from increasing the purpose of this utility model is to provide one kind and can bear moment
The sloth wheel gear of impact torsion.
To achieve the above object, the utility model provides following technical solution: a kind of sloth wheel gear, including gear sheet
Body is equipped with the connection ring of coaxial arrangement, the connection ring and the gear in the central axis hole of the gear
It is connected between inner hole wall by several screw rods, the gear inner hole wall is equipped with corresponding with the screw rod flexible
Hole, described screw rod one end are screwed onto the connection ring, stretching on gear inner wall described in the movable insertion of the other end
In shrinkage cavity, the first rubber sleeve, the second rubber sleeve and top pressure spring are socketed on the screw rod, first rubber sleeve one end is supported
It connects in the upper surface of the top pressure spring, the other end and the inner wall of the gear abut against, second rubber sleeve one end
It is connected to the lower end surface of the top pressure spring, the other end and the outer wall of the connection ring are abutted against, set in the gear
There is oil leab, which is arranged along the radial direction of the gear and leads in the inner hole of the gear.
The screw rod is to be symmetricly set on the outer wall of the connection ring in pairs.
The outer diameter of the screw rod and the internal orifice dimension of the top pressure spring match.
The screw rod is arranged on the bisector of the gear thickness.
This structure of the utility model, in other transmission gear transmission process, by huge moment impact
When torsion, gear can generate certain shrink space by top pressure spring and rubber sleeve, avoid sending out with other transmission gears
Generate biggish abrasion after the stiff shock boldly confronted a powerful opponent, due to abrasion reduction therefore can realize avoid gap increase and can
Bear the technical effect of moment impact torsion.
The utility model is further described with reference to the accompanying drawings and detailed description.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of specific embodiment of the present invention；
Fig. 2 is the cross-sectional view of specific embodiment of the present invention.
Specific embodiment
The utility model is specifically described below by embodiment, is served only for carrying out the utility model further
Illustrate, should not be understood as the restriction to scope of protection of the utility model.
As shown in Figure 1 and Figure 2, present embodiment discloses a kind of sloth wheel gears, including gear 1, in gear 1
It is equipped with the connection ring 2 of coaxial arrangement in central axis hole, is connected between 1 inner hole wall of connection ring 2 and gear by four screw rods 3,
1 inner hole wall of gear is equipped with telescopic hole 11 corresponding with screw rod 3, and 3 one end of screw rod is screwed onto connection ring 2, the other end
It is movable insertion 1 inner wall of gear on telescopic hole 11 in, be socketed on screw rod 3 first rubber sleeve 4, the second rubber sleeve 5 with
And top pressure spring 6, the coefficient of elasticity K of top pressure spring 6 are arranged in 80N/mm or so, can make in this way connection ring 2 and gear 1 it
Between tensile force it is bigger, stability is more preferable, wherein 4 one end of the first rubber sleeve is connected to the upper surface of top pressure spring 6, the other end with
The inner wall of gear 1 abuts against, and 5 one end of the second rubber sleeve is connected to the lower end surface of top pressure spring 6, the other end and connection ring
2 outer wall abuts against, and gear 1 is equipped with oil leab 7, which is arranged simultaneously along the radial direction of gear 1
Lead in the inner hole of gear 1.
In order to make screw rod 3 connect relatively reliable stabilization, the quantity of screw rod 3 is symmetricly set on to the outer wall of connection ring 2 in pairs
On, minimum is two pairs, and the internal orifice dimension of the outer diameter and top pressure spring 6 of screw rod 3 matches, while the setting of screw rod 3 is thick in gear 1
On the bisector of degree.
By above structure, which is rushed with other transmission gear transmission process by huge moment
When hitting torsion, gear 1 can generate certain shrink space by top pressure spring 6 and rubber sleeve, avoid and other driving cogs
Wheel generates biggish abrasion after very stiff and demanding shock occurs, and avoids gap from increasing simultaneously because therefore the reduction of abrasion can be realized
And the technical effect of moment impact torsion can be born.
