Background technique
The master winch of conventional internal clutch in use, easily occurs that clutch friction plate is burnt to death, problems such as finding not in time, maintenance is poor revealed by hydraulic oil; Based on above in esse technical problem, use wet type external formula clutch configuration, effectively can extend clutch friction plate working life; During hydraulic fluid leak, can flow out from the vent of clutch, Timeliness coverage oil leakage fault; Clutch friction plate damages or after leakage of oil, whole master winch retarder is no longer dismantled from complete machine by maintenance clutch, after clutch is taken apart by complete machine, carries out keeping in repair just can.
Summary of the invention
Object of the present invention provides a kind of external wet clutch of strong rammer master winch retarder just for the clutch the deficiencies in the prior art part of current master winch retarder, wet clutch structure of the present invention effectively can increase radiating effect, extend clutch working life, and when clutch easily damaged parts damages, effectively improve its maintenance.
Object of the present invention can be realized by such as following technique measures:
The external wet clutch of strong rammer master winch retarder of the present invention comprises the diameter of axle section being arranged on the clutch active hub in a tray hollow posts chamber in coaxial line mode by bearing, bearing housing; The front end of described tray combines with master winch retarder reel in coaxial line mode, and rear end is combined with clutch gear ring by affixed support ring flat-plate; Be meshed by the clutch component be jointly made up of annular steel disc and the annular friction sheet of spaced inside and outside toothing between the gear at described clutch gear ring and clutch active hub rear portion; Be provided with at the rear portion of clutch component for realizing clutch component combination, the piston be separated and piston baffle, described piston and piston baffle are by being encapsulated in the cavity of clutch gear ring with the clutch outside plate of clutch gear ring rear end Joint; Described piston forms by annular piston body with by the spring that clutch outside plate is fitted in several spring mounting holes that piston only rear end processes; Described piston and piston baffle are set in together in coaxial line mode by the shoulder hole cooperatively interacted, hydraulic fluid chamber is provided with between the ladder table top that piston and piston baffle cooperatively interact, this hydraulic fluid chamber is connected with swivel joint by the oil duct that piston baffle body is arranged, and described swivel joint is connected with hydraulic oil source.
Annular steel disc of the present invention is outer toothing; Described annular friction sheet is internal tooth arrangement.
The present invention is provided with annular liner plate between described clutch component and support ring flat-plate, and the outer ring surface of annular liner plate is processed with the outer toothing be meshed with clutch gear ring internal tooth.
X-shaped sealing ring, back-up ring for confining liquid pumping cavity is installed between piston of the present invention and the junction plane of piston baffle; The good seal performance when form that described X-shaped sealing ring adds back-up ring can ensure that piston opened by hydraulic oil.
The clutch closed chamber being full of lubricant oil being provided with oil filling hole is jointly formed in the present invention by the diameter of axle and oil sealing that support ring flat-plate, clutch gear ring, clutch outside plate and clutch active hub, in use, Mobil Mobilfluid 424 lubricant oil is added in clutch, for ensureing that clutch annular friction plate in use has good radiating effect, to increase heat radiation and to extend annular friction sheet working life.
Working principle of the present invention is: during the work of master winch retarder, and its inner all part is the common entirety rotated; When hydraulic oil passes in swivel joint, hydraulic oil passes through oil duct, enter in the oil pocket between piston and piston baffle, owing to being subject to the effect of hydrodynamic pressure, piston is thrown off to the right, Compress Spring, until piston and clutch outside plate are by mean place, now annular steel disc and annular friction sheet are thrown off, and can produce relative movement, realize clutch gear ring and clutch initiatively hub relatively rotate, thus realize the function of master winch retarder free releasing.
Beneficial effect of the present invention is as follows:
Clutch due to retarder dog point of the present invention and free off the hook end have employed external and arranges, for retarder itself, after throw-out-of clutch, before rotating by master winch retarder the annular friction sheet brought, a large amount of heat of wearing and tearing generation just makes dog point and free off the hook end heat effectively be scattered and disappeared by structure of the present invention mutually, promotes the working life of annular friction plate.In addition, because the dog point of prior art and the clutch of free off the hook end are all within the roll built-in, when annular friction sheet or internal seal structure damage, need to disassemble whole master winch just can keep in repair, and external clutch configuration of the present invention can solve the maintenance problem of master winch preferably, occur because when bad seals and annular friction sheet damage, master winch can be pulled down from complete machine and just can keep in repair at master winch.
