The utility model provides a motor protection device for a small screw oil press, including a motor, a reducer and a screw. One end of the screw is assembled at the output end of the reducer, and a buffer seat with a middle hole is also included. The buffer seat is sleeved on the screw and the bottom surface is affixed to the outer wall of the reducer. The middle hole on the top of the buffer seat is also provided with a coaxial shaft. The thrust ball bearing comprises a seat ring, a rolling body and a shaft ring. The seat ring is assembled in the sinking platform and the bottom surface of the sinking platform is connected with the inner bottom surface. The screw is provided with a circumferential axial stop part, and the axial stop part is connected with the top surface of the shaft ring. During the operation of the screw, the reverse force will be transmitted to the thrust ball bearing through the axial stop part of the screw. The force will be dispersed to the buffer seat through the rotation of the thrust ball bearing, and then transmitted to the reducer housing from the buffer seat. The contact area between the buffer seat and the outer casing is large and the force is balanced. The reverse force of the screw is dispersed to the reducer outside. Therefore, the reducer can be damaged.

一种小型螺杆榨油机的电机保护装置
本技术涉及家用榨油装置
,具体是指一种小型螺杆榨油机的电机保护装置。
技术介绍
随着人们对食品安全的越来越重视,传统的食用油生产模式已悄然发生变化,许多的家庭选择自榨,也有商家选择小批量现场压榨,目的都是使生产过程透明放心。与之相应的家用榨油机也越来越普及,其中螺杆类的小型榨油机在使用过程中,随着压榨推送的原料增加,螺杆会产生较大的反向力,从而导致驱动螺杆转动的减速机及电机损坏。
技术实现思路
本技术的目的是提供一种可避免螺杆在运转过程中损坏减速机及电机的电机保护装置。为实现上述目的,本技术所采用的技术方案为:一种小型螺杆榨油机的电机保护装置,包括电机、减速机及螺杆,螺杆的一端装配于减速机的输出端,还包括一带中孔的缓冲座,缓冲座套设于螺杆上且底面贴合于减速机外壁,缓冲座顶面的中孔处还设有同轴心的沉台,沉台内设有平底座垫型单向的推力球轴承,所述推力球轴承包括座圈、滚动体和轴圈,座圈装配于沉台内且底面抵接沉台的内底面,螺杆设有绕周的轴向止挡部,轴向止挡部抵接于轴圈的顶面。进一步,所述螺杆的另一端套设有一向心轴承,向心轴承外通过一带出渣孔的环形支架固定于榨膛内壁。其有益效果是:螺杆在运转过程中,反向力会通过螺杆的轴向止挡部传递至推力球轴承,通过推力球轴承的旋转将力分散至缓冲座,再由缓冲座传递至减速机外壳,缓冲座与外壳的接触面积较大,且受力均衡,螺杆的反向力被分散至减速机外壳,因此可避免减速机被损坏;螺杆的另一端通过向心轴承与榨膛配合,能进一步避免螺杆径向摆动而损坏减速机及电机。附图说明下面结合附图和具体实施例对本技术作进一步详细的 ...
