Fig. 1 is a schematic structural diagram of a first embodiment of the present invention;
fig. 2 is a partially enlarged view of the connection portion of the connection pipe and the body in fig. 1.
Wherein: 1. a body; 2. a breathing hole; 3. a connecting pipe; 4. a respirator; 5. an upper vertical pipe; 6. a lower vertical pipe; 7. an intermediate pipe; 8. mounting a plate; 9. a bolt; 10. a connecting screw hole; 11. an annular ring; 12. A seal ring; 13. an annular seal ring; 14. an annular gasket.
Detailed Description
The invention will be further described with reference to the following drawings and examples:
the first embodiment is as follows: referring to fig. 1 and 2, the oil-injection-preventing speed reducer comprises a machine body 1, wherein a breathing hole 2 is formed in the top of the machine body, a connecting pipe 3 is installed on the breathing hole, and a respirator 4 is arranged on the top of the connecting pipe;
the connecting pipe comprises an upper vertical pipe 5, a lower vertical pipe 6 and an intermediate pipe 7 which are mutually communicated, the bottom of the lower vertical pipe is connected with the breathing hole, the respirator is installed at the top of the upper vertical pipe, the upper vertical pipe is arranged above the side part of the lower vertical pipe in parallel, two ends of the intermediate pipe are respectively connected with the bottom of the upper vertical pipe and the top of the lower vertical pipe, and an included angle of 90-150 degrees is formed between the intermediate pipe and the upper vertical pipe.
In this embodiment, the organism takes a breath through breathing hole, connecting pipe and respirator, and under normal conditions, the inside oil of organism can spout from breathing hole upwards, spouts into in the connecting pipe, and through the respirator blowout, blocks up the respirator. However, in this embodiment, since the connecting pipe has two bending portions, a certain included angle is formed between the middle pipe and the upper vertical pipe and between the middle pipe and the lower vertical pipe, so that a bend is formed between the upper vertical pipe and the middle pipe, and a bend is formed between the middle pipe and the lower vertical pipe, so that the oil is firstly sprayed into the lower vertical pipe through the breathing hole, and when continuously sprayed upwards, the oil is firstly blocked by the bending portion between the lower vertical pipe and the middle pipe, so as to reduce the impact force and speed of the oil spraying upwards as much as possible, and even if the oil is continuously sprayed upwards along the middle pipe, the oil touches the bending portion between the middle pipe and the upper vertical pipe, and is further blocked by the bending portion, so that the impact force of the oil spraying upwards can be further reduced, the oil rising speed can be reduced, so that the oil can not rise into the breather, and then the oil automatically falls back into the machine body under the weight, so that the breathing hole and the respirator can normally give the body air change work. Therefore, the loss of oil in the machine body can be prevented, the maintenance rate of the machine body is reduced, and the service life is prolonged.
Referring to fig. 1 and 2, the bottom of the lower vertical pipe is mounted on the top of the machine body through a mounting plate 8, a plurality of groups of screw holes are formed in the top of the machine body, the plurality of groups of screw holes are annularly and uniformly distributed outside the breathing holes, and the mounting plate is connected with the screw holes through a plurality of groups of bolts 9 in a locking mode.
Referring to fig. 1 and 2, a connection screw hole 10 is formed in the middle of the mounting plate, the connection screw hole is arranged right opposite to the breathing hole, external threads are formed on the outer edge face of the bottom of the lower vertical pipe, and the bottom of the lower vertical pipe is connected with the connection screw hole through the external threads in a threaded connection mode.
The connecting pipe is connected with the machine body through the mounting plate, so that the machine body is convenient to maintain and disassemble and is also convenient to assemble. Wherein, because connecting pipe and respirator are in the top of organism, when normal transportation, in order to reduce the occupation of space, prevent that the connecting pipe from bending or splitting, can utilize the end cap to plug up the breathing hole earlier, mounting panel, connecting pipe and respirator follow-up installation can. Wherein, if say that the connecting pipe is bent or is split after receiving external force carelessly, directly will descend the standpipe to screw out in the connecting screw hole, change new connecting pipe can, need not to change the mounting panel is whole, and the cost is cheaper. Meanwhile, sealing materials such as raw rubber belts and the like can be added at the screwed connection position of the lower vertical pipe and the connecting screw hole, so that the leakage condition at the connection position of the connecting screw hole and the connecting pipe is prevented.
Referring to fig. 1 and 2, the bottom surface of the mounting plate is provided with an annular ring 11 extending downwards, the inner wall of the annular ring is flush with the inner wall of the connecting screw hole, the annular ring is clamped in the breathing hole, and the inner wall of the annular ring abuts against the outer wall of the breathing hole.
The annular ring with be equipped with sealing washer 12 between the breathing hole, the top of sealing washer is equipped with annular seal 13 of outwards extending, annular seal set up in the mounting panel with between the organism. Wherein, an annular gasket 14 is arranged between the mounting plate and the machine body, and a bolt passes through the annular gasket and is connected with the screw hole in a threaded manner.
Through the setting of annular ring, directly utilize the annular ring card to go into in the breathing hole, after the connecting pipe is connected with the mounting panel like this, can prevent to appear leaking between arc hole and the connecting pipe to, when mounting panel and organism were installed, directly go into the arc hole with the annular ring card, can guarantee to connect screw and the coaxial setting of breathing hole, prevent the emergence of the condition of revealing. The setting of sealing washer can increase between annular ring and the breather hole sealedly, prevents that junction between them from revealing, and the setting of annular sealing washer further increases sealed effect.
Simultaneously, go up the standpipe and locate in the top of standpipe side down, the respirator can set up in the top of breather side like this, can be according to actual conditions, adjusts the position that the respirator was in, and also the respirator can be according to actual conditions, rotates down the standpipe and is connected the turned angle of screw, adjusts the position of respirator, can adjust the position of respirator like this according to organism mounted position, can be applicable to the mounted position that the organism is different, improves the application scope of organism installation.
