Abstract
The utility model discloses a camshaft and belongs to a transmission shaft. The camshaft generally mounted in a high-pressure water pump comprises a camshaft body. A recess used for a motor rotary shaft to insert is arranged at one end of the camshaft body, a key groove used for holding a flat key is arranged on a recess wall, a seal ring cavity section used for mounting a seal ring is arranged at an open end of the recess, and the seal ring cavity section and the recess are coaxial. The camshaft can effectively prevent water leaking from a plunger cavity from flowing into the recess, and accordingly the recess wall and the motor rotary shaft inserted into the recess are prevented from corroding due to long-time soaking in water.
Description
Technical field:
The utility model relates to a kind of transmission shaft, specifically is a kind of camshaft that is applied in the high-pressure water pump.
Background technique:
Mainly by the rotation of driven by motor camshaft, the eccentric segment of camshaft promotes connecting rod makes plunger do straight reciprocating motion through slide block (crosshead) during high-pressure water pump work, finally is issued to the purpose of suction liquid in the keying effect of pump head inlet valve.One end of conventional camshaft is typically provided with the shrinkage pool that the power supply machine rotating shaft is inserted; Have the keyway that is used to place flat key on the shrinkage pool wall; After machine shaft inserts in the shrinkage pool, drive the camshaft rotation, because high-pressure water pump in the course of the work through flat key; Therefore the water that leaks out in the plunger cavity cause the shrinkage pool wall and the machine shaft that inserts in the shrinkage pool corrodes because of being immersed in water for a long time in regular meeting flow into shrinkage pool.
The model utility content:
The technical problem that the utility model will solve is to provide a kind of and can prevent effectively that the water that in plunger cavity, leaks out from flowing in the shrinkage pool, thereby avoid the shrinkage pool wall and insert the camshaft that the machine shaft generation in the shrinkage pool is corroded.
The technical solution of the utility model is; A kind of camshaft with following structure is provided: comprise the camshaft body; Camshaft body one end is provided with and is used for the shrinkage pool that the power supply machine rotating shaft is inserted, and has the keyway that is used to place flat key on the shrinkage pool wall, wherein; The opening end of shrinkage pool is provided with the seal ring chamber section that is used to install seal ring, and seal ring chamber section is coaxial with shrinkage pool.
After adopting above structure; Compared with prior art; The utility model camshaft has the following advantages: because the utility model camshaft is provided with the seal ring chamber section that is used to install seal ring at the opening end of shrinkage pool; Therefore, after machine shaft inserted in the shrinkage pool, the seal ring of installing in the section of seal ring chamber can be sealed up shrinkage pool; Thereby prevented that effectively the water that in plunger cavity, leaks out from flowing in the shrinkage pool, avoided the shrinkage pool wall and inserted the interior machine shaft of shrinkage pool corroding because of being immersed in water for a long time.
Description of drawings:
Fig. 1 is the main TV structure schematic representation of the utility model camshaft.
Embodiment:
Below in conjunction with accompanying drawing and embodiment the utility model camshaft is done further explain:
As shown in Figure 1; In this embodiment; The utility model camshaft comprises camshaft body 3, and camshaft body 3 left ends are provided with and are used for the shrinkage pool 2 that the power supply machine rotating shaft is inserted, and have the keyway 4 that is used to place flat key on shrinkage pool 2 walls; The opening end of shrinkage pool 2 is provided with the seal ring chamber section 1 that is used to install seal ring, and seal ring chamber section 1 is coaxial with shrinkage pool 2.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technological scheme of the utility model all should fall into the protection domain that the utility model claims are confirmed.
