TWI241389B - Replaceable ball deflector - Google Patents

Abstract

The present invention relates to a replaceable ball deflector, which makes up of the fixed substance and the turned substance. The characteristic of the replaceable ball deflector is that both the fixed substance and the turned substance have a combined structure to combine together. And the types of the turned substance are in accordance with the pitch center diameter, the ball diameter and the lead of the ball screw to install in the ball screw and to guide the balls turning. Therefore the fixed substance can be a common element for the different turned substances.

Description

241389 V. Description of the invention (1) [Technical field to which the invention belongs The present invention relates to the use of a ball redirector for ball bearings, from the screw spiral groove and the return pipeline, as a field] structure. The recirculation system of the roller screw, so that the bearing pipe surrounded by the screw grooves of the ball screw is turned into a turning motion to guide the ball into the return pipe. [Previous technology] It consists of traditional ball screw system. Ball screw ball is used as a repetitive circular motion bow. The ball enters the current ball screw from the bearing pipe. As shown in the twelfth figure, the turning surface 53 is formed as a single body. The turning 50 is fixed to the nut 53 to guide the ball from the bearing diameter, For the combination of lead and ball, you must change the steering gear gauge. Secondly, because the contact surface during the traditional collision is a small contact area, which leads to a large, increase the steering gear and roll up. As mentioned above, the above system, the return of the rod, in the eight return return steering gear 50 'its The upper diameter of the pipe is 50mm, and the ball flow system is used for the return system pipe. Generally, the screw and the ball screw are provided with a swivel forming square shaft 51, and the two ends of the turn and the nut phase are fed into the return pipe by the fixed fixed shaft 51 and the steering body 52; when any of the rolling factors are changed, therefore When the ball screw nut and the return lever are actuated, the diverter is manufactured in a guided manner, and the body 5 2 and the turn fit are used to pitch the entire ball screw with a turning surface, which results in a new excessive steering surface. The turning surface of the turning device 50 is flat. It is in contact with the ball, and the contact area is small, so that the impact force is concentrated on the damage of the steering gear 50 and the local stress of the ball. It is necessary to improve the knowledge and technology.

On page 6, there is a joint for the ball rolling into the steering wheel, and the fixed foot is suitable for the ball turner. Therefore, the two steering wheels are combined with a single fixed diameter and lead to combine the turn; therefore, it is fixed on the nut. Luming's steering is designed with its grooves and screw fits, and the ball return steering tube device with a lead screw includes a combination of a component for a non-directional device and a foot of the invention to form a steering foot. Use the nuts of the fixed cap to move the feet, according to the specifications, the cap screw steering feet lead to the screw flow pipe device, and the way; the first fixed parts share the same specifications. The combination is replaced by a two-way configuration. The specifications are a common and incorporated in the firmware. Turn the groove. 〇According to the ball, a spiral groove is provided at one end between the steering grooves to make the first hair and turn to the ball that matches each other. The ball of the ball is unidirectionally fixed by the upward direction of the fixed parts used for rolling. 1241389 Five 2. Description of the invention (2) [Summary of the invention] The bead of the present invention is characterized by a turning operation: and a ball steering gear of which the steering feet are all one hundred has the same specifications. The second part is the diameter of the hair, the ball straight end is provided with a joint fixed to the nut. The ball diverter is fixed to the return pipe of the spiral groove phase screw screwed to the diameter of the hair and the screw nut of the lead screw. The ball rolls in and out of the ball screw rod of the ball screw, which is fixed and connected to form a complete structure, which can be replaced without screws. Docking combination_ 6 Steering gear can be composed of steering gear or zhuzhu steering gear. The fixed section of the ball screw is fixed, and two of them are provided with supporting parts above the fixed part to hold the pitch diameter of the fixed screw on the whole piece, and the roller feet are kept on each ball. Its cross section is adjacent to the turning surface of the screw and screw. Between ball and screw groove

Description of the invention (3) In addition, in order to increase the private H "^ ~ s ir ::; combining 1 solid two to achieve ,,,, ° structure, such as the protruding long-handed hibiscus, you can ^ The adjacent ten are convex or concave Γding = determined by the nut: set as the nut moves: 结合 Γ the joint between the fixed part of the nut of the nut and the steering foot, 『:: = hat moves. And The freedom of the hair to move downwards and to the sides, two: 冓 is mainly to limit the steering groove, T-shaped vertical groove cut from top to bottom, the shape can be a horizontal dovetail groove,: shape: ... etc. A variety of combined shapes. The wedge-shaped groove and the rounded surface under the cymbal fit to the screw, and the surface of the ball screw steering gear with the screw groove on the outer side of the ball steering gear is in contact with the tangent line, which can resist the screw in both directions. The spiral groove of the cap; the rotation of the ball steering gear caused by the ball steering gear on this cutting plane: to avoid solid copper, magnesium alloy, etc., which are both lightweight, high-strength, and expensive. In addition, the present invention considers the More material for steering. Because the value of the stress on the steering surface of the ball steering gear is proportional to the force of two f, the surface pressure, and when the ball impacts In the same situation, the size of the contact surface is inversely proportional to the contact area; in other words, under the birch, the ground stress will reduce the impact stress. Therefore, the contact area can be made into a circular arc surface. Increasing the ball hitting the ball turn = the steering surface contact area of the device can reduce the phenomenon of local stress increase, and the contact with the ball when the surface is damaged. In addition, the fixing device of the present invention is a ball steering device. Page 8 V. Description of the invention (4) The corresponding geometrical shape of the card holder can be used to fix the mouth of the mouth, and it can also be screwed and fixed on the fixing part and the bolt and bolt hole. ϊΐΐ :: Understand the characteristics and technical contents of the present invention ...
