Description
技术领域technical field
本实用新型涉及一种电梯曳引机的零部件安装结构，特别是一种电梯曳引机中定子线圈的安装结构。The utility model relates to a component installation structure of an elevator traction machine, in particular to a stator coil installation structure in the elevator traction machine.
背景技术Background technique
现有的电梯曳引机中，定子线圈一般通过涨紧销与曳引机机座内的固定座连接。但是，这样的连接稳定性不理想，涨紧销的涨紧作用容易失效，定子线圈容易转动；而且，为了防止定子线圈径向振动，固定座和定子线圈为过盈配合连接，固定座上与定子线圈连接的连接面需要进行精加工防止尺寸误差过大，但连接面过大，加工成本较高。因此，现有的电梯曳引机的定子线圈安装结构存在着连接稳定性不理想，定子线圈较易转动和加工成本较高的问题。In the existing elevator traction machine, the stator coil is generally connected to the fixed seat in the traction machine frame through tension pins. However, the stability of such a connection is not ideal, the tensioning effect of the tension pin is likely to fail, and the stator coil is easy to rotate; moreover, in order to prevent the radial vibration of the stator coil, the fixed seat and the stator coil are connected by an interference fit, and the fixed seat and the stator coil are connected by an interference fit. The connection surface of the stator coil needs to be finished to prevent excessive dimensional errors, but the connection surface is too large, and the processing cost is high. Therefore, the existing installation structure of the stator coil of the elevator traction machine has the problems of unsatisfactory connection stability, easy rotation of the stator coil and high processing cost.

本实用新型的目的在于，提供一种电梯曳引机的定子线圈安装结构。本实用新型不仅能够确保连接稳定性，防止定子线圈转动，还具有降低加工成本的作用。The purpose of the utility model is to provide a stator coil installation structure of an elevator traction machine. The utility model can not only ensure the connection stability and prevent the rotation of the stator coil, but also has the effect of reducing the processing cost.
本实用新型的技术方案：电梯曳引机的定子线圈安装结构，包括曳引机机座，曳引机机座内设有固定座；固定座表面设有若干凹槽，固定座上通过定位销连接有定子线圈；定子线圈内圈上设有若干径向向内的凸起。The technical solution of the utility model: the installation structure of the stator coil of the elevator traction machine includes a traction machine frame, and a fixing seat is arranged inside the traction machine frame; several grooves are arranged on the surface of the fixing seat, and positioning pins pass through the fixing seat The stator coil is connected; the inner ring of the stator coil is provided with several radially inward protrusions.
前述的电梯曳引机的定子线圈安装结构中，所述凸起的位置与凹槽的位置相对应，凸起的宽度略大于凹槽的宽度，凸起和凹槽的底面之间设有空隙。In the aforementioned stator coil installation structure of the elevator traction machine, the position of the protrusion corresponds to the position of the groove, the width of the protrusion is slightly larger than the width of the groove, and there is a gap between the bottom surface of the protrusion and the groove .
与现有技术相比，本实用新型改进了电梯曳引机的定子线圈安装结构，不仅在曳引机机座内的固定座上设置了凹槽和定位销，还在定子线圈的内圈上设有与凹槽配合的凸起；一方面通过定位销固定定子线圈的位置，防止定子线圈转动；一方面通过凹槽和凸起的配合进一步确保定子线圈和固定座的连接，防止定子线圈转动。而且，空隙的设置使凸起不和凹槽底面接触，减小了固定座和定子线圈的接触面，从而减小了需要精加工的面积，降低了加工成本。因此，本实用新型不仅能够确保连接稳定性，防止定子线圈转动，还具有降低加工成本的作用。Compared with the prior art, the utility model improves the installation structure of the stator coil of the elevator traction machine. Not only grooves and positioning pins are arranged on the fixed seat in the traction machine frame, but also on the inner ring of the stator coil. There is a protrusion that matches the groove; on the one hand, the positioning pin is used to fix the position of the stator coil to prevent the stator coil from rotating; on the other hand, the cooperation between the groove and the protrusion further ensures the connection between the stator coil and the fixing seat to prevent the stator coil from rotating . Moreover, the arrangement of the gap prevents the protrusion from contacting the bottom surface of the groove, thereby reducing the contact surface between the fixing seat and the stator coil, thereby reducing the area requiring finishing and reducing the processing cost. Therefore, the utility model can not only ensure the stability of the connection and prevent the rotation of the stator coil, but also has the effect of reducing the processing cost.
