Abstract
The utility model relates to a split joint of a rotating shaft. The split joint is characterized in that: the joint comprises a front shaft, a middle shaft, a rear shaft, a middle sleeve, an oil-distributing sleeve and a water-distributing sleeve that are split; after assembling, the middle shaft is located between the front shaft and the rear shaft; the middle sleeve is sleeved outside the middle shaft; and the oil-distributing sleeve and the water-distributing sleeve are sleeved outside the rear shaft. The advantages are as follows: after the split structure is adopted, the processing process is simplified, the measure operability is good, the size precision is favorable, and the axiality of the split structure is better than that of the overall structure.
Description
Technical field
The utility model relates to a kind of rotating shaft joint, is used for the hydraulic oil and the electric system of getting off are transported to the actuating unit of getting on the bus in engineering machinery field.
Background technology
Rotating shaft joint is applied on the construction machinery and equipments such as hoisting crane, excavating machine, and it is the device that a kind of handle hydraulic oil of getting off and electric system are transported to the actuating unit of getting on the bus.Rotating shaft joint commonly used is an one-piece construction, is made up of main shaft and main body two parts.Main body is made of rotor, stator and sealing member again.Rotor is fixed on the turn table, follow the turn table revolution, stator is fixed on the chassis motionless, is provided with the oil circuit that is connected by annular oil groove between rotor and the stator, by the rotation change of rotor and the angle between the stator hydraulic fluid port, thus the output port of change hydraulic oil.
In the past, the complete dependence on import of rotating shaft joint, its price is expensive unusually, has increased the productive costs of enterprise.After treating the rotating shaft joint production domesticization, face a new difficult problem again.Because rotating shaft joint commonly used is an one-piece construction, so main shaft and main body are long usually, and the processing comparison difficulty of getting up is difficult to guarantee right alignment.And seal groove on the main body and distribution channel are processed the bad detection in back because the hole is deep, add the restriction of processing technology, and whole assembling back result of use is not good.
Summary of the invention
The purpose of this utility model provides a kind ofly not only processes easy but also can guarantee the rotating shaft joint of right alignment.
In order to achieve the above object, the technical solution of the utility model has provided a kind of split type rotating shaft joint, it is characterized in that, comprise split front axle, axis, rear axle, middle cover, join oil jacket and water distribution cover, after the assembling, axis has middle cover at middle outer shaft sleeve between front axle and rear axle, outer shaft sleeve has the oil jacket of joining and water distribution cover in the back.
Further, seal by native sand between described axis and the described middle cover, described joining between oil jacket and described water distribution cover and the described rear axle seals with seal ring by O shape combination rotating seal ring and piston rod respectively, seals by O-ring seals between described axis and the described rear axle.
Outer shaft sleeve has big flange in described, and big flange is arranged in the side of cover, seals by O-ring seals between big flange and the middle cover.
On described inwall of joining oil jacket and water distribution cover, be embedded with guide ring respectively.
On the rear end of described rear axle, be provided with bonnet.
Described front axle comprises the axis body that has through hole, is provided with flange in the rear end of axis body, is embedded with O-ring seals on the inwall of through hole front end.
Described rear axle comprises the adapter shaft that has through hole, is provided with butt flange on the front end of adapter shaft, and baffle plate is located on the adapter shaft, and baffle plate is positioned at the rear of butt flange.
The utility model carries out according to the principle of work of rotating shaft joint, utilizes mandrel to be connected multiple fluid pressure mediums such as also can carrying Oil, Water, Gas continuously with the relative motion interrupted, rotation continuously of overcoat; Meanwhile, change traditional one-piece construction into split-type structural, guaranteed the rotating property of mandrel and overcoat better.
The utility model has the advantages that: after adopting split-type structural, simplified processing technology is measured workablely, and dimensional accuracy is relatively good, obviously is better than one-piece construction.
Description of drawings
A kind of split type rotating shaft joint scheme drawing that Fig. 1 provides for the utility model;
Fig. 2 is the front axle scheme drawing;
Fig. 3 is the rear axle scheme drawing.
The specific embodiment
Below in conjunction with embodiment the utility model is described.
Embodiment
As shown in Figure 1, a kind of split type rotating shaft joint that provides for the utility model, comprise split front axle 2, axis 3, rear axle 7, middle cover 4, join oil jacket 8 and water distribution cover 11, after the assembling, axis 3 is provided with bonnet 12 on the rear end of rear axle 7 between front axle 2 and rear axle 7, cover 4 in being with outside axis 3, outside rear axle 7, be with and join oil jacket 8 and water distribution cover 11, on the inwall of joining oil jacket 8 and water distribution cover 11, be embedded with guide ring respectively.Be with big flange 6 outside axis 3, big flange 6 is arranged in the side of cover 4, seals by O-ring seals between big flange 6 and the middle cover 4.
Pass through native sand 5 sealings between axis 3 and the described middle cover 4, join and pass through O shape combination rotating seal ring 9 and piston rod seal ring 10 sealings between oil jacket 8 and water distribution cover 11 and the described rear axle 7 respectively, seal by O-ring seals between axis 3 and the rear axle 7.
As shown in Figure 2, front axle 2 comprises the axis body 13 that has through hole, is provided with flange 14 in the rear end of axis body 13, is embedded with O-ring seals 1 on the inwall of through hole front end.
As shown in Figure 3, rear axle 7 comprises the adapter shaft 17 that has through hole, is provided with butt flange 15 on the front end of adapter shaft 17, and baffle plate 16 is located on the adapter shaft 17, and baffle plate 16 is positioned at the rear of butt flange 15.
During deep hole working, earlier with the positioning spigot of front axle 2 upper flanges 14 and an end fit on of axis 3, subsequently with the positioning spigot of butt flange 15 on the rear axle 7 and the other end fit on of axis 3, connect fastening with tie bolt then, deep hole processing, treat that deep hole working is over, with front axle 2, axis 3, rear axle 7 separately, difference processing oil oral pore, seal with O ring groove.
