Specific embodiment
In conjunction with shown in attached drawing, the technical solution of the utility model is further described:
A kind of threephase asynchronous machine IP56 shaft end oil seal protection structure, the protection structure includes axis 1, lateral bracket 2, oil sealing
Part 3, the lateral bracket 2 pass through axis 1, and the oil seal 3 is circular ring shape, and the oil seal 3 passes through axis 1, the oil seal 3 and side
Bracket 2 contacts.
In the present embodiment, lateral bracket 2 is equipped with groove 201, and wherein groove 201 is arranged on 2 outer surface of lateral bracket, groove
201 connect with the centre bore of lateral bracket 2, and oil seal 3 is made of upper spacer 301 and the connection of lower clapboard 302, between two pieces of partitions
Angle is acute angle.Wherein the upper spacer 301 of oil seal 3 and lower clapboard 302 respectively with two face contacts of groove 201.Oil seal 3
Two contact surfaces, economic benefits and social benefits sealing, sealing effect enhancing are formed with groove 201.
201 depth of groove is 2.5-5mm, and in the present embodiment, the depth of groove 201 is 4.5mm.
