Abstract
The utility model discloses a resilient gear wheel coupling device, which is mainly used for power transmission in a diesel engine or for other usages. The utility model comprises a coupling joint (1) and spring seats (7), wherein the spring seats (7) are oppositely arranged inside a spring groove on the coupling joint (1) and an abutting spring is disposed between the spring seats (7). The utility model is characterized in that a stop pin (8) is fixed on each spring seat (7), the spring consists of an inner ring spring (5) and an outer ring spring (4), the inner ring spring (5) and the outer ring spring (4) are mutually sleeved, and the stop pin (8) is inserted into an inner hole of the spring. Compared with the prior art, the pulling and pressing range of the spring is limited during work because of the stop fins oppositely arranged inside the spring, and over intension of the spring caused by excessive power is prevented, thereby effectively protecting the spring, reducing maintenance time and improving transmitting capacity. In addition, the double-layer spring structure increases elasticity.
Description
Technical field
The utility model relates to a kind of resislient gear hitch bar, is mainly used in the power transmission on the diesel engine, also can be used for other.
Background technique
At present, the resislient gear structure that diesel engine uses is that shaft coupling is arranged, be provided with spring groove in the shaft coupling, relative spring seat is arranged in spring groove, spring is between spring seat, spring and spring seat be eight groups and evenly distribute on the circumferencial direction of shaft coupling, is inserted with between the adjacent group with gear joins and stirs pawl, and the endoporus of gear and shaft coupling is in coaxial state.During work, gear rotates and stirs the spring seat that is adjacent through stirring pawl, transmits another spring seat and shaft coupling through spring again, has played the buffer function of power in this process.The hitch bar of this structure, the tension and compression scope of spring does not effectively limit, and makes spring under the repeated stock of overload effect, phenomenons such as spring ejection, fracture often occur.
Summary of the invention
The purpose of this utility model provide a kind of to spring have protective action, work medi-spring do not eject the resislient gear hitch bar that does not rupture, overcome the deficiencies in the prior art.
Resislient gear hitch bar of the present utility model, comprise shaft coupling 1, the spring seat 7 that is oppositely arranged is arranged in the spring groove on shaft coupling 1, between spring seat 7, be provided with and lean spring, it is characterized in that: be fixed with pin 8 on each spring seat 7, described spring is made up of the interior coil spring 5 and the cycle spring 4 of mutual sheathing, and pin 8 inserts the spring endoporus.
The utility model compared with prior art; because relative pin is arranged in spring; tension and compression scope to spring in the work limits; the stressed excessive phenomenon that compresses of ambassador's spring of crossing can not appear; effectively protected spring; reduce engineering time, the double-layer spring structure has increased elastic force, has improved transmission capacity.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is an A-A cross-sectional schematic shown in Figure 1.
Embodiment
As shown in Figure 1, 2: shaft coupling 1 is arranged, be provided with spring groove in the shaft coupling 1, relative spring seat 7 is arranged in spring groove, spring is between spring seat 7, and spring and spring seat are eight groups and evenly distribute on the circumferencial direction of shaft coupling 7.Be inserted with between the adjacent group with gear 9 joins and stir pawl 11, gear 9 is in coaxial state with the endoporus of shaft coupling 1.
Be fixed with pin 8 on each spring seat 7, spring is made up of the interior coil spring 5 and the cycle spring 4 of mutual sheathing, forms the double-layer spring structure, and pin 8 inserts the spring endoporus.
Be fixed with the cover plate 6 that spring and spring seat structure is played barrier effect in a side of shaft coupling 1 by bolt 2, opposite side has baffle ring 10 to be used for carrying out spacing to stirring pawl 11 by bolt.
During work, gear 9 rotates stirs the spring seat 7 that is adjacent through stirring pawl 11, transmits another spring seat and shaft coupling through spring again, has played the buffer function of power in this process.As stressed excessive, the pin 8 that is oppositely arranged can contact, and has prevented that spring from by excessive compression, effectively having protected spring.
Claims (1)
1, a kind of resislient gear hitch bar, comprise shaft coupling (1), the spring seat (7) that is oppositely arranged is arranged in the spring groove on shaft coupling (1), between spring seat (7), be provided with and lean spring, it is characterized in that: be fixed with pin (8) on each spring seat (7), described spring is made up of the interior coil spring (5) and the cycle spring (4) of mutual sheathing, and pin (8) inserts the spring endoporus.
