Specific implementation mode

Following explanation is done to the performance of this shaft coupling and use occasion with reference to embodiment part：

Engine also becomes dynamic power machine, such as various motor, engine and various hydraulic power units etc., usually Straight line power or rotary power can be provided, the engine in the present embodiment is the mechanical equipment that can export axial power, For example, various reciprocating hydraulic cylinders, cylinder, linear motor, electric pushrod etc., that is to say, that the power category of this kind of equipment output Type is linear thrust or pulling force.

Working machine, the functional component for executing specific function, such as wheel drive system, Lathe turning tool execution part, Various molds, power head etc., main effect are to execute.

Shaft coupling described in the utility model is just for connection to engine and working machine, as a part for transmission, For completing the transmission of axial power, and filters out and circumferentially rotate.

In conjunction with Figure of description 1 to Fig. 4, which includes power input shaft 100, power output shaft 200, thrust axis It holds, self-aligning bearing, bearing cap 300 and the connector positioned at both ends, is described in detail with reference to function.

Power input shaft 100 is followed successively by interconnecting piece I 110 and axis hole from left to right, and central axis hole is three ladder axis holes, Three bearing chambers are formed inside axis hole, three bearing chambers are followed successively by the first thrust bearing room 120, self-aligning bearing room from left to right 130 and the second thrust bearing room 140.Place the first thrust bearing 410, self-aligning bearing 430 and respectively in three bearing chambers Two thrust bearings 420.Interconnecting piece I 110 is connect by screw-thread fit or pin connection with first connector 510 in outside.

The effect of first connector 510 is to connect power input shaft and engine, the connecting interface of the first connector 510 Form can be the patterns such as axle sleeve, flange, hinged ear, be reliably connected as long as can play.

Power output shaft 200 is followed successively by axle bearing mount portion 210 and interconnecting piece II 220, bearing attachment 210 from left to right For ladder shaft-like, corresponds to the first thrust bearing, self-aligning bearing and the second thrust bearing, interconnecting piece 220 respectively from left to right and pass through Screw-thread fit or bayonet fittings and second connector 520 in outside connect.The function and connecting interface of second connector 520 can To refer to the first connector.

The left-half of above-mentioned power output shaft is inserted in the axis hole of power input shaft, and is set successively at the two cooperation Set the first thrust bearing 410, self-aligning bearing 430 and the second thrust bearing 420.Wherein, the first thrust bearing setting is pushed away first In power bearing chamber, the first thrust bearing both ends of the surface act on first bearing room and power output shaft shaft end, form axial force distribution. Self-aligning bearing is located in self-aligning bearing room, is circumferentially rotated for bearing.The inner ring of self-aligning bearing 430 is mounted on by clamp spring 431 On power output shaft.Second thrust bearing 420 is mounted in the second thrust bearing room, and passes through round shelves ring on power output shaft 421 and stop nut 422 carry out axially position, meanwhile, the second thrust bearing room external port using bearing cap 300 carry out axis To positioning, bearing cap loosens in order to prevent, at the threaded engagement face between bearing cap and power input shaft using pin 310 into The locking processing of row.Further, it is provided with spanner on bearing cap and applies blind hole 320, is used for the operation of spanner.

The dynamic process of the shaft coupling is as follows：

When engine (such as hydraulic cylinder) straight reciprocating motion, axial driving force can be exported by this shaft coupling Into working machine, when engine is that hydraulic motor drives, this shaft coupling cannot transmit rotary power into working machine, also It is to say, by the implementation of this shaft coupling, the purpose of transfers driving force may be implemented.

Embodiment described above is only that preferred embodiments of the present invention are described, not to this practicality Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, relevant technical staff in the field is to this The various modifications of utility model and improvement should all expand in the protection domain as determined by the utility model claims book.
