Detailed Description
The following description of the embodiments refers to the accompanying drawings, which are included to illustrate specific embodiments in which the invention may be practiced.
As shown in fig. 1 and 2, the present embodiment discloses a steering machine including a large-torque, high-rigidity steering housing. This high rigidity of big moment of torsion turns to casing includes main part 1 and helping hand tip 2, have the lead screw cavity 11 that is used for installing the lead screw in the main part 1, belt pulley cavity 21 and the vice cavity 22 of lead screw have in the helping hand tip 2, belt pulley cavity 21 is used for installing the belt pulley, the vice cavity 22 of lead screw is used for installing the lead screw vice, belt pulley cavity 21 is linked together with the vice cavity 22 of lead screw, so that the belt pulley drives the lead screw and attaches the rotation, the vice cavity 22 of lead screw is linked together with lead screw cavity 11, so that the vice and lead screw coaxial coupling of lead.
The one end of the existing rack is processed into a screw rod, the screw rod pair and the screw rod are driven by a belt pulley to transmit, and coaxial transmission is realized in the transmission process due to the adoption of a screw rod transmission mode, so that the radial force is basically eliminated coaxially, the transmission is more stable, the steering gear can bear larger torque, and the motor can output larger power assistance. Meanwhile, a pressing block hole does not need to be machined and manufactured on the steering engine shell with large torque and high rigidity, only the belt pulley is used for driving the screw rod pair and the screw rod to transmit in the transmission hole, the structure is simple, and machining and manufacturing are convenient.
A partition plate 23 is arranged in the boosting end part 2, the partition plate 23 is positioned between the belt pulley cavity 21 and the screw pair cavity 22, and through holes are formed between the two ends of the partition plate 23 and the inner wall surface of the boosting end part 2. Two through holes formed by the two ends of the partition plate 23 and the power-assisted end part 2 are used for a transmission space of a belt in the rotating process, so that the stability of the steering gear shell with large torque and high rigidity in use is improved.
The screw pair cavity 22 is internally provided with a plurality of reinforcing ribs 24 which extend along the longitudinal direction of the main body part 1. The integral structural strength of the power-assisted end part 2 can be effectively enhanced through the plurality of reinforcing ribs 24, and the service life of the steering engine shell with large torque and high rigidity is prolonged. Wherein the main body part 1 and the booster end part 2 are integrally formed. The steering engine shell with large torque and high rigidity is convenient to process and manufacture and higher in stability.
The above disclosure is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the invention, which is defined by the appended claims.
