Abstract
The utility model discloses an injection pump transmission device for a diesel engine, which comprises an injection pump transmission connection device in transmission connection with an injection pump as well as a transmission shaft transmission connection device intended to be connected with a transmission shaft, wherein, the injection pump transmission connection device is provided with a vibration reduction device, and the vibration reduction device is in transmission connection with the transmission shaft transmission connection device. The utility model has the effects of effectively reducing the vibration of the injection pump, reducing the vibrating effect on the transmission shaft, improving the performance of the injection pump, reducing the failure rate of the injection pump, and prolonging the service life of the diesel engine.
Description
Technical field
The utility model relates to a kind of transmission device, especially relates to the transmission joint that a kind of diesel injection pump is used.
Background technique
The connection of Injection Pump transmission system on the existing diesel is to be connected with transmission shaft after a common coupling is connected with flange plate by assembling, and the transmission of power of transmission shaft is realized the work of Injection Pump to Injection Pump.And diesel engine is in the long-time running process, because the vibration amplitude during Injection Pump work itself is bigger, can have a negative impact to Injection Pump, transmission shaft after the long-time running like this, and concerning Diesel Engine Complete Machine, can increase complete machine oscillation, influence the Diesel Engine Complete Machine life-span.And said structure can make Injection Pump and transmission shaft because above-mentioned vibration initiating failure under the situation of the pump end pressure raising of Injection Pump.
Summary of the invention
Technical problem to be solved in the utility model has provided a kind of vibration of effective reduction Injection Pump, reduce influence of vibration simultaneously to transmission shaft, improve the working condition of Injection Pump, reduce the rate of fault of Injection Pump, can prolong the diesel engine fuel injecting pump drive assembly in the life-span of diesel engine simultaneously.
For solving the problems of the technologies described above, the technical solution of the utility model is: the diesel engine fuel injecting pump drive assembly, comprise the Injection Pump transmission joint that is in transmission connection with Injection Pump and be used to be connected transmission shaft transmission shaft transmission joint, described Injection Pump transmission joint is provided with vibration damping equipment, the described vibration damping equipment described transmission shaft transmission joint that is in transmission connection.
As a kind of improvement, described Injection Pump transmission joint is the coupling that is in transmission connection with described Injection Pump.
As further improvement, described transmission shaft transmission joint is a mounting flange.
As further improvement, described vibration damping equipment is the cylindric land that is connected with described coupling, and described land connects described flange plate.
The diesel engine fuel injecting pump drive assembly of technique scheme, adopted the Injection Pump transmission joint to be provided with vibration damping equipment, the transmission shaft transmission joint mode and vibration damping equipment is in transmission connection, effect is stably played in operation to Injection Pump, the vibration situation of Injection Pump is effectively reduced, reduce influence of vibration simultaneously, improve the working condition of Injection Pump transmission shaft, reduce the rate of fault of Injection Pump, can prolong the life-span of diesel engine simultaneously.Series connection increases land on the Injection Pump coupling and adopt, by land with after flange plate is connected, go to connect the mode of transmission shaft again by flange plate, the vibration frequency of diesel injection pump drive line is changed, reduce the influence of the vibration of high pressure oil pump, the vibration amplitude of Injection Pump is reduced transmission shaft, the diesel injection pump operating ratio is more steady, reduce the rate of fault of Injection Pump and transmission shaft, the life-span of having improved Injection Pump and transmission shaft, the life-span of prolongation diesel engine.
Description of drawings
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Accompanying drawing is the structural representation of the utility model diesel engine fuel injecting pump drive assembly;
Embodiment
As shown in drawings, the diesel engine fuel injecting pump drive assembly, comprise that the Injection Pump transmission joint that is in transmission connection with Injection Pump is connected transmission shaft transmission shaft transmission joint with being used to, the Injection Pump transmission joint is provided with vibration damping equipment, the transmission shaft transmission joint and vibration damping equipment is in transmission connection.The coupling that the Injection Pump transmission joint can adopt Injection Pump to be in transmission connection, the transmission shaft transmission joint can adopt mounting flange, vibration damping equipment then can adopt the cylindric land mode that is connected with coupling, realizes and being connected of transmission shaft by land mounting flange mode like this.
Like this after the diesel engine fuel injecting pump drive assembly increases land, the vibration frequency of diesel engine fuel injecting pump shaft system changes, reduce the influence of the vibration of high pressure oil pump to transmission shaft, and behind the increase land, the vibration amplitude of Injection Pump reduces, and the diesel injection pump operating ratio is more steady, reduces the rate of fault of Injection Pump and transmission shaft, improve the life-span of Injection Pump and transmission shaft, can prolong the life-span of diesel engine simultaneously.
More than be the application's a embodiment, should be understood that these embodiments only be used to the invention is described and be not used in the restriction the invention scope.Should be understood that in addition those skilled in the art can make various changes or modifications the invention after the content of having read the invention instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
