Description
Technical field
The utility model belongs to excavator drive components field, is specifically related to a kind of single channel high pressure high-rotation speed rotary connector.
Background technique
Single channel high pressure high-rotation speed rotary connector flange one end is connected with speed reducer bolt, if but swivel joint is connected bad with speed reducer, and swivel joint easily comes off.As sealed the bad situation that fluid seepage will occur.There is radial unbalance loading in swivel joint, swivel joint turning axle and revolving shell disalignment, make wearing and tearing increase in real work, and the compression of product inner seal ring is unbalanced, thus form fluid seepage.Axially locating is complicated, the bad control of axial float.
Model utility content
The purpose of this utility model is to provide a kind of single channel high pressure high-rotation speed rotary connector, solves the problems referred to above.
The utility model single channel high pressure high-rotation speed rotary connector, comprise turning axle and be enclosed within the revolving shell on turning axle, axial oil groove is provided with in turning axle, turning axle outside is provided with annular oil groove, axial oil groove is communicated with annular oil groove, annular oil groove both sides are vertically provided with high-pressure rotational combined seal ring, turning axle bottom is provided with the location shaft shoulder, turning axle top has been threaded round nut, adopt the location shaft shoulder and round nut axially locating, because of the change of sense of rotation, and getting loose of nut can not be caused when High Rotation Speed.
The below of the location shaft shoulder is provided with flange, and be provided with end face seal O type circle below flange, flange is connected with rotating equipment, avoids the phenomenon that gets loose that swivel coupling produces in rotary course.
High-pressure rotational combined seal ring outside is vertically provided with twice support ring and twice low pressure O RunddichtringO successively, adopt twice low pressure O RunddichtringO, can effectively avoid fluid seepage, adopt twice support ring, prevent seal ring to compress the unbalanced fluid leakage problems caused.
Be provided with large washer between round nut and revolving shell, round nut is provided with lock washer.
Revolving shell has hydraulic fluid port, and hydraulic fluid port is communicated with annular oil groove, and hydraulic fluid port is directly processed on revolving shell cylindrical, avoids welding hydraulic fluid port, the welding stress of generation.
Compared with prior art, the utility model has the advantage of:
1, increase by 2 road low pressure O RunddichtringOs, can effectively avoid fluid seepage; 2, adopt 2 road support rings, prevent seal ring to compress the unbalanced fluid leakage problems caused; 3, seal groove is placed on turning axle, and swivel joint endoporus is less, is convenient to assembling, processing; Small product size is little, is convenient to transport, assembling etc.; 4, adopt the shaft shoulder and round nut axially locating, because of the change of sense of rotation, and getting loose of nut can not be caused when High Rotation Speed; 5, hydraulic fluid port is directly processed on housing cylindrical, avoids welding hydraulic fluid port, the welding stress of generation; 6, turning axle is provided with flange and is connected with rotating equipment, avoids the appearance of swivel coupling phenomenon that gets loose that connecting thread produces in rotary course.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1, end face seal O type circle, 2, turning axle, 3, high-pressure rotational combined seal ring, 4, support ring, 5, low pressure O RunddichtringO, 6, revolving shell, 7, large washer, 8, lock washer, 9, round nut, 10, hydraulic fluid port, 11, the location shaft shoulder, 12, flange.
Embodiment
Contrast accompanying drawing below, embodiment of the present utility model is described in further detail.
