The utility model discloses a honeycomb ceramic makes's isolation ball and dust ring can the noise reduction, simple structure, excellent in use effect.
Description
The technical field is as follows:
the utility model relates to a ball of low noise is vice.
The background art comprises the following steps:
the noise that produces in the vice working process of ball is an important index that influences the vice performance of ball always, and in order to the noise reduction, improves the vice quality of ball, this patent has proposed the ball of a low noise vice.
The invention content is as follows:
the utility model provides a ball screw of low noise is vice for solving the problem that above-mentioned prior art exists.
The utility model discloses the technical scheme who adopts has:
the utility model provides a ball screw of low noise is vice, includes lead screw, nut, ball and reverser, nut threaded connection is on the lead screw, and a plurality of balls set up side by side and form the ball unit, the ball unit is located between lead screw and the nut, and the reverser is fixed in on the outer wall of nut, and the ball unit passes through the reverser and realizes the cyclic motion between lead screw and nut, its characterized in that: set up an isolation ball between two adjacent balls in the ball unit, isolation ball adopts sound absorbing material to make, and its surface is equipped with honeycomb holes.
Further, the sound-absorbing material is honeycomb ceramic.
Furthermore, the two ends of the nut are provided with dustproof rings, the dustproof rings are fixed on the nut through screws, and the inner surfaces of the dustproof rings are honeycomb-shaped.
Furthermore, the dust ring is made of honeycomb ceramics.
Further, the diameter of the isolation ball is 90-95% of the diameter of the ball bearing.
The utility model discloses following beneficial effect has:
the utility model discloses a honeycomb ceramic makes's isolation ball and dust ring can the noise reduction, simple structure, excellent in use effect.
Description of the drawings:
fig. 1 is an internal structure diagram of the present invention.
Fig. 2 is an external structure view of the present invention.
The specific implementation mode is as follows:
the present invention will be further described with reference to the accompanying drawings.
As shown in fig. 1 and fig. 2, the utility model relates to a ball of low noise is vice, including lead screw 1, nut 2, ball 3 and reverser 4, nut 2 threaded connection is on lead screw 1, a plurality of ball 3 set up side by side and form the ball unit, the ball unit is located between lead screw 1 and the nut, reverser 4 is fixed in on the outer wall of nut 2, the ball unit realizes the cyclic motion between lead screw 1 and nut 2 through reverser 4, set up an isolation ball 5 between two adjacent balls 3 in the ball unit, the diameter of isolation ball 5 is 90-95% of ball 3 diameter. The isolation ball 5 is made of sound-absorbing material, the surface of the isolation ball is provided with honeycomb holes, and the sound-absorbing material is honeycomb ceramic.
The utility model discloses be the isolation ball that adds an acoustic material between per two adjacent balls and make, the diameter ratio ball of isolation ball is slightly littleer. The isolation ball can be made of honeycomb ceramics, the honeycomb ceramics is a ceramic product with a structure similar to a honeycomb, when the ball screw pair works, the ball moves and rubs to generate noise, and when sound waves are incident to the surface of a material, most of the sound waves enter the honeycomb ceramic ball along the small hole tunnels in a labyrinth mode. The sound wave propagates in the honeycomb ceramic ball to cause air vibration in the pores and rubs with ceramic ribs with rough surfaces forming the pores, a part of sound energy is converted into heat energy, a part of sound energy reaches the rigid wall and is reflected back to the honeycomb ceramic ball, the sound wave returns to a labyrinth small-hole tunnel like primary incident sound again, the air and the ceramic ribs are driven to rub, and the sound energy is continuously converted and consumed. The two effects interact with each other, so that the honeycomb ceramic ball effectively consumes incident sound energy, and various noises generated in the running process of the ball are effectively reduced.
The two ends of the nut 2 are provided with dustproof rings 6, the dustproof rings 6 are fixed on the nut 2 through screws 7, and for further reducing noise, the inner surfaces of the dustproof rings 6 are cellular and are also made of honeycomb ceramics.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, several modifications can be made without departing from the principle of the present invention, and these modifications should also be regarded as the protection scope of the present invention.
