Description
Technical Field
The utility model relates to the technical field of engineering machinery, in particular to a coupler transmission device for an ultra-large energy level dynamic compactor
Background
The coupler transmission device is a main component of power transmission in engineering machinery, in the dynamic compaction machine, one end of the coupler transmission device is connected with a flywheel disc on an engine output shaft to receive power input, and the other end of the coupler transmission device is connected with a reduction gearbox for adjusting the speed ratio to transmit stable power; since stable power transmission is required, the mounting accuracy and maintainability of the coupler transmission device are highly required.
The dynamic compactor with the tamping energy level exceeding 10000kN.m is called as the super-large-energy-level dynamic compactor, and the super-large-energy-level dynamic compactor is different from other dynamic compactors and has the most remarkable characteristic that the super-large-energy-level dynamic compactor needs stable power transmission with low speed and large torque and has higher installation precision requirements on a coupler transmission device.
The existing coupler transmission device is in a single-side supporting mode, part of the existing coupler transmission device is in a protection mode, the input end of the existing coupler transmission device is an elastic connecting disc, then a hydraulic coupler, a single-side supporting seat and an elastic sleeve pin coupler are sequentially connected to complete output, and meanwhile, a coupler shell, a diesel engine flywheel shell and a supporting seat are installed to protect the elastic connecting disc and the hydraulic coupler.
The installation accuracy requirement of the coupler transmission device refers to the coaxiality requirement of an output shaft of the diesel engine, a transmission shaft of the coupler and an input shaft of the speed reducer, and the positions of the coupler transmission device mainly refer to the connection and installation of an input end and an output end, namely the connection and installation of an elastic connecting disc and a flywheel disc of the diesel engine and the connection and installation of an elastic sleeve pin coupling and the speed reducer. The coaxiality requirement can be understood as axial, radial and angular installation deviations.
The input end of the diesel engine is provided with an elastic connecting disc, the elastic connecting disc is connected with a flywheel disc of the diesel engine through a shaft in the middle of the elastic connecting disc and a bearing in the middle of the flywheel disc of the diesel engine for positioning, and then the elastic connecting disc is connected with the flywheel disc through an elastic sleeve pin to transmit power. At the moment, the angular installation deviation is the biggest influence of the input end installation precision, and the adjustment is generally completed by adjusting four supporting points of the tail margin of the diesel engine, and the more the supporting points are, the greater the difficulty is.
And the output end is an elastic sleeve pin coupler, and the elastic sleeve pin coupler is connected with the speed reducer by connecting an elastic sleeve pin on the elastic sleeve pin coupler with a half coupler on the speed reducer to transmit power. In this case, the radial and angular mounting deviations, which are the most significant influences on the mounting accuracy of the output end, are generally achieved by adjusting the mounting plane of the support base. Although the adjusting supporting points are few, the diesel engine and the coupler transmission device are adjusted together when the coupler transmission device is adjusted due to the fact that the coupler transmission device is a single fulcrum, and the difficulty is higher due to the fact that the adjustment is equivalent to the adjustment with 5 fulcrums.
Thirdly, for the protection of the shell, besides the difficulty of installing and adjusting the above two transmission devices with the protection coupler on the unilateral bearing, the protective cover of the shell blocks most space, although the protection function can be increased, the installation becomes more difficult at the same time.
Therefore, how to provide a coupler transmission device for an ultra-large energy level dynamic compactor to solve the above technical problems is a technical problem that needs to be solved urgently by those skilled in the art.
