Abstract

The utility model relates to an improvement of oil pump base connecting mechanism of transformer, comprising a motor axle and an oil pump base. The motor axle is enclosed in the oil pump base and is provided with thread; a bolt is thrilled into the base to connect with the motor axle, and the tail of the bolt is welded on the base and the welded position is planished; therefore, the oil would not leak from the oil pump base. The motor axle of the current transformer oil pump base extends to the outside of the pump shell and connects tightly with a big nut, and then is tightly sealed with rubber gasket and spring gasket; when in use for certain period, the oil will leak out from the base. The utility model overcomes oil leakage.

Description

Improved transformer oil pump frame syndeton
Technical field:
The utility model relates to a kind of improvement of transformer oil pump frame syndeton.
Background technology:
Motor on the existing transformer oil pump frame stretches out the pump case base plate with motor shaft and is fastenedly connected with big nut, and fitted seal such as rubber gasket and spring washer are arranged simultaneously.So just oil seepage phenomena occurs easily, influence the oil pump operate as normal, and maintenance is difficult.
Summary of the invention:
The purpose of this utility model provide a kind of have not can seepage oil transformer oil pump frame syndeton, make transformer oil pump in use safer.
Solution of the present utility model is to make motor shaft not stretch out the oil pump base, is shaped on the screw thread with screw fit on motor shaft, passes base with sunk screw and links to each other with motor shaft, and is directly that base and screw weldering is dead and polish after fastening.
Owing to adopted sunk screw on the shell base, to fixedly connected, and the screw afterbody welded with base extremely polish, make that the oil pump base can seepage oil with motor shaft, and easy for installation.
Description of drawings:
Fig. 1 is the utility model structural representation.
Embodiment:
As shown in Figure 1, the utility model is a kind of syndeton that is positioned on the transformer oil pump frame, it comprises motor shaft 1, oil pump base 3 etc., this motor shaft 1 does not stretch out the oil pump base, and is shaped on screw thread on it, has a screw 2 to be through on the base 3 and links to each other with motor shaft 1, then that screw afterbody and base is welded together, and the face of weld polished.The oil pump base does not just have the leakage of oil generation like this.
