Embodiment 1

[0029] Such as figure 1 Shown, adopt following steps to prepare bearing saddle elastic pad of the present invention:

[0030] 1) Add 50 parts by weight of caprolactam and a friction coefficient modifier (hydroxyl-terminated polybutadiene liquid rubber) into the first reactor, and add another part of 50 parts by weight of caprolactam into the second reactor, melt and vacuum dehydrate for 10 minutes ;

[0031] 2) Add catalyst (sodium hydroxide) to the first reaction kettle, and vacuum dehydrate for 15 minutes;

[0032] 3) Add an activator (triphenylmethane triisocyanate) to the second reaction kettle, and vacuum dehydrate for 5 minutes;

[0033] 4) mixing the materials in the first reactor and the second reactor, injecting them into a molding mold, and polymerizing them into an integrated blank;

[0034] 5) The blank is boiled in water, and then machined into a bearing saddle elastic pad product. The saddle elastic pad prepared by the above method is used as a saddle elastic...

Abstract

The invention relates to an elastic cushion of a load bearing saddle. The elastic cushion of a load bearing saddle is characterized by being integrated into a whole by nylon elastomer materials. The invention further relates to a preparation method and the application of the elastic cushion.

Description

technical field [0001] The invention relates to an elastic pad, in particular to an elastic pad for railway vehicle components. The invention also relates to the preparation method and application of the elastic pad. Background technique [0002] The bearing saddle is one of the important parts of the railway vehicle bogie. This part makes the weight transmitted from the car body evenly distributed to the bearing and journal, and plays an important role in preventing the unbalanced load of the combustion shaft. It is installed on the rolling bearing of the car. Bear and transmit loads between the bogie side frame and the pedestal frame. The role of the railway freight car bogie is to support the car body, guide the vehicle along the track, and bear various loads from the car body and the line. The bogie consists of a bolster, two side frames, two sub-frames and two wheelsets, the ends of which are directly fitted with the saddle surfaces of the sub-frames. During operatio...
