Abstract
The utility model discloses a steering screw structure for a power-assisted steering gear, which comprises a steering screw, a roller path and a steel ball, the steering screw rod is provided with threads, the raceway is arranged on the steering screw rod and is positioned on the right side of the threads, the steering screw is matched with the steel ball through a roller path, an arc groove is arranged on the roller path, the cross section of the roller path is of an arc structure, the steering screw rod is matched with the steel ball conveniently through the roller path, the centers of the roller path, the steel ball and the arc groove are on the same plane, the lubricating grease is stored in the arc groove, and the abrasion dust and impurities generated in the rotating process of the steering screw rod increase the lubrication, reduce the friction among the steering screw rod, the steel ball and the bearing outer ring, meanwhile, the stored lubricating grease has the lubricating and noise reducing effects on the continuous rotation of the steering screw and the steel ball, the smoothness and the fluency of rotation are improved, and the service life of the steering gear is prolonged.
Description
Technical Field
The utility model relates to the technical field of steering screws, in particular to a steering screw structure for a power steering gear.
Background
The steering screw, the steel balls and the bearing outer ring form an inner and outer ring angular contact ball bearing structure, and when the screw rotates, the steel balls rotate between the screw roller path and the bearing outer ring. After lubricating grease is coated in the roller path, an oil film is formed among the steel ball, the screw roller path and the bearing outer ring, if the oil film is damaged, the steering screw, the steel ball and the bearing outer ring have the risks of serious abrasion and even clamping and abnormal sound, so that the service life of the steering gear is rapidly reduced, and even the steering gear cannot work normally. A steering screw structure for a power steering gear is proposed to address this problem.
SUMMERY OF THE UTILITY MODEL
The technical problem to be solved by the utility model is to overcome the existing defects, and provide a steering screw structure for a power-assisted steering gear, which has novel structural design, increases lubrication, contains impurities, reduces friction among the steering screw, a steel ball and a bearing outer ring, prolongs the service life of the steering gear, and can effectively solve the problems in the background art.
In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a steering screw structure for power assisted steering ware, includes steering screw, raceway and steel ball, be provided with the screw thread on the steering screw, the raceway sets up on steering screw, and the raceway is located the right side of screw thread, steering screw passes through the raceway and cooperates with the steel ball, be provided with the circular arc groove on the raceway.
Furthermore, the cross section of the roller path is of a circular arc structure, and the steering screw rod is conveniently matched with the steel ball through the roller path.
Furthermore, the centers of the roller path, the steel ball and the arc groove are on the same plane, lubricating grease is stored through the arc groove, and abrasive dust and impurities generated in the rotating process of the steering screw rod are increased, so that the friction among the steering screw rod, the steel ball and the bearing outer ring is reduced, the lubricating grease stored at the same time plays a role in lubricating and reducing noise for the continuous rotation of the steering screw rod and the steel ball, the smoothness and smoothness of rotation are improved, and the service life of the steering gear is prolonged.
Compared with the prior art, the utility model has the beneficial effects that: this a steering screw structure for power assisted steering ware has following benefit:
the utility model is provided with the arc groove, lubricating grease is stored through the arc groove, and abrasive dust and impurities generated in the rotating process of the steering screw rod are generated, so that the lubrication is increased, the friction among the steering screw rod, the steel ball and the bearing outer ring is reduced, meanwhile, the stored lubricating grease plays a role in lubricating and noise reduction on the continuous rotation of the steering screw rod and the steel ball, the smoothness and smoothness of the rotation are increased, the service life of the steering gear is prolonged, and the steering screw rod and the steel ball are conveniently matched through a roller path.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Referring to fig. 1-2, the present invention provides a technical solution: a steering screw structure for a power steering gear comprises a steering screw 1, a raceway 2 and a steel ball 4, wherein the steering screw 1 is provided with a thread 4, the raceway 2 is arranged on the steering screw 1, the section of the raceway 2 is of an arc structure, the steering screw 1 is conveniently matched with the steel ball 4 through the raceway 2, the raceway 2 is positioned on the right side of the thread 4, the steering screw 1 is matched with the steel ball 4 through the raceway 2, the raceway 2 is provided with an arc groove 3, lubricating grease and abrasive dust and impurities generated in the rotating process of the steering screw 1 are stored through the arc groove 3, lubrication is increased, friction among the steering screw, the steel ball and a bearing outer ring is reduced, meanwhile, the stored lubricating grease has the lubricating and noise reducing effects on the continuous rotation of the steering screw 1 and the steel ball 5, the smoothness and smoothness of rotation are increased, the service life of the steering gear is prolonged, the structure is novel in design, the lubrication is increased, the impurity is contained, the friction between the steering screw rod, the steel ball and the bearing outer ring is reduced, and the service life of the steering gear is prolonged.
When in use: steering screw 1 is in the use, because rotate the running-in can produce impurity such as abrasive dust, abrasive dust impurity etc. assembles in circular arc groove 3 department along with steering screw 1's rotation, avoided impurity attached to raceway 2, to raceway 2 on steel ball 5 and the bearing outer ring, the continuous wearing and tearing of steel ball 5 and bearing outer ring, the lubricating grease that circular arc groove 3 stored simultaneously plays the lubrication and noise reduction effect to steering screw 1 and the continuous rotation of steel ball 5, increase pivoted ride comfort and smoothness nature, improve the working life of steering gear.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
