Abstract
Provided is a high-speed ball nut including a nut body, the two ends of the nut body are respectively provided with a ball reverser groove, a ball reverse channel penetrated through the nut body along the axial direction is arranged between the two bal reverser groove, and the axes of the ball reverse channel and the nut body are parallel. According to the above narration, the ball nut provided integrates all the advantages of inner and outer circulations, the structure is compact because the shape and size are designed based on an inner circulation manner, and an outer circulation manner is adopted when the ball is on a reverse direction to come off the rolling channel, all rolling channels are provided with balls to circulate thereon, so the ball nut provided has high bearing capability; the optimized parallel design of the axes of the ball reverse channel and the nut body can improve the smoothness of the ballscrew pair during the running process, moreover, the ball nut provided can adapt to the high-speed rotation of the balls in the nut body and can release the heat generated from the rotary well, thereby greatly reducing the temperature rise of the whole member and improving the precision of the ballscrew pair.
Description
Technical field
The utility model relates to a kind of ball nut, relates in particular to a kind of high speed ball nut.
Background technique
Along with the continuous lifting of Numeric Control Technology and developing rapidly of numerical control industry, machine industry is more and more higher to the performance index and the production required precision of rolling function parts ball screw pair, be to adapt to market development, researching and developing the transmission that a kind of ball nut satisfies high-speed, high precision is problem anxious to be solved.
Summary of the invention
The utility model is at the existing in prior technology shortcoming, and provide a kind of technological scheme that can ball nut, this scheme has been assembled all advantages of inside and outside circuit, boundary dimension is by interior circulation nut, compact structure, and ball breaks away from raceway when reverse, by the outer circulation mode, all raceways all have ball in circulation, thereby carrying is big, this scheme can adapt to the high speed rotary of ball in nut body, and can discharge the heat that produces in the revolution better, has reduced the temperature rise of whole parts widely, reduce distortion, can improve the precision of ball screw pair, and the optimal design of ball backward channel improves the flexibility of ball screw pair in running, and can keep the highi degree of accuracy of ball screw pair better.
The utility model is realized by following technical measures: a kind of high speed ball nut, it comprises nut body, the two ends of described nut body are respectively arranged with the reverse tank of ball, be provided with a ball backward channel in axial direction that runs through nut body, described ball backward channel, the two parallel axes of nut body between two reverse tanks of ball.
The beneficial effect of this programme can be learnt according to the narration to such scheme, the optimal design of ball backward channel, nut body person's parallel axes, can improve the flexibility of ball screw pair in running, this scheme can adapt to the high speed rotary of ball in nut body, and can discharge the heat that produces in the revolution better, reduce the temperature rise of whole parts widely, can improve the precision of ball screw pair.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure, 1, the reverse tank of ball, 2, nut body, 3, the reverse tank of ball, 4, the ball backward channel.
Embodiment
For clearly demonstrating the technical characterstic of this programme,, this programme is set forth below by an embodiment.
A kind of ball nut, as shown in Figure 1, it comprises nut body 2, the two ends of described nut body 2 are respectively arranged with the reverse tank 1,3 of ball, be provided with a ball backward channel 4 in axial direction that runs through nut body 2, the parallel axes of described ball backward channel 4, nut body 2 between two reverse tanks of ball.
The utility model can pass through or adopt existing techniques in realizing without the technical characteristics of describing; do not repeat them here; certainly; above-mentioned explanation is not to be to restriction of the present utility model; the utility model also is not limited in above-mentioned giving an example; variation, remodeling, interpolation or replacement that those skilled in the art are made in essential scope of the present utility model also should belong to protection domain of the present utility model.
