Description
Technical field
The utility model is related to a kind of end cover type ball nuts that can be threaded connection with, and belong to ball nut technical field.
Background technology
Screw thread is the key component being threadedly coupled with worm drive, and threaded connection is a kind of widely used dismountable solid
Fixed connection has many advantages, such as that simple in structure, connection is reliable, is convenient to mount and dismount.Traditional thread measurement method is to utilize external thread gauge
It carries out contact or carries out manual measurement, heavy workload using universal tool-measuring microscope, the low of efficiency rule is imitated in work, and measurement result is easy
By man's activity.
End cover type ball nut processes a longitudinal hole on nut, as the return pass of ball, the cover board at nut both ends
On be provided with the backhaul mouth of ball, thus ball enters return duct, form cycle.Cannula type ball nut, it uses bend pipe as returning
Return pipe road, this processability of product structure is good, but since pipeline protrudes outside nut body, radial dimension is larger.Spiral groove type ball spiral shell
Mother, it is that helicla flute is milled out in nut outer circle, and the both ends of slot drill out through-hole and, formation backward channel tangent with screw thread,
This structure is smaller than cannula type structure radial dimension, but manufactures more complex.
When making object of which movement, need directly or by other mechanisms to convey the movement that power generates indirectly in general
To final movement portion.By taking engine as an example, the burning due to gasoline in engine makes piston move up and down, then passes through intermediate machine
Structure is eventually transferred to wheel and is allowed to that rotary motion occurs.In the world today, machinery, dress that there are various motions can be represented
It sets, it suffices to say that none is not to have some form of movement conduction mechanism.Ball screw assembly, is to convert rotary motion to straight line
Movement, or by transform linear motion be rotary motion most rational product.Ball wire bar pair is between leading screw and nut with steel
Ball is the worm drive element of rolling element.Rotary motion can be changed into linear motion by it, or linear motion is changed into rotation
Transhipment is dynamic.Therefore ball screw assembly, is both transmission original paper, and linear motion mutually converts element with rotary motion.Traditional rolling
Pearl nut is connect with equipment base to be connected by being located at the flange face bolt of nut end；And with the demand of distinct device,
The fixation for needing to be threadedly coupled between nut and equipment base to realize nut and reduction space hold；But it was producing
Cheng Zhong cannot achieve end-surface type ball back cycle if directly processing the external screw thread for connection on ball nut
Structure.Mobile distance can not be accurately measured when much ball nut work at present, operating temperature state can not be understood, and do not have
There is oil lubrication, affects working efficiency.
