Bearing seat assembly and converter device

A bearing seat assembly, comprising:

• a first bearing seat including a mounting space and a first bottom portion;
• a second bearing seat mounted in the mounting space of the first bearing seat, and the second bearing seat including a second bottom portion;
• and
• linear bearings mounted between the first bottom portion and the second bottom portion, the second bearing seat being supported by the linear bearings, such that a space is formed between the second bottom portion and the first bottom portion, and the second bearing seat being linearly movable relative to the first bearing seat;
• wherein the second bottom portion includes a convex portion protruding toward the first bottom portion in a central portion of the second bottom portion in a width direction of the bearing seat assembly;
• and
• wherein a concave portion opposite to the convex portion is formed in the first bottom portion, the concave portion having an opening that is open toward the convex portion, and the convex portion is inserted into the concave portion by passing through the opening, and wherein two shoulder portions protruding toward the second bottom portion are formed in the first bottom portion, the concave portion is formed between the two shoulder portions, and the shoulder portions protrude closer to the second bottom portion than flat surfaces disposed directly adjacent the shoulder portions.

A converter device, comprising:

• a radial bearing;
• a shaft;
• and
• a bearing seat assembly, comprising:
• a first bearing seat including a mounting space and a first bottom portion;
• a second bearing seat mounted in the mounting space of the first bearing seat, and the second bearing seat including a second bottom portion;
• and
• linear bearings mounted between the first bottom portion and the second bottom portion, the second bearing seat being supported by the linear bearings, such that a space is formed between the second bottom portion and the first bottom portion, and the second bearing seat being linearly movable relative to the first bearing seat;
• wherein the second bottom portion includes a convex portion protruding toward the first bottom portion in a central portion of the second bottom portion in a width direction of the bearing seat assembly;
• wherein a concave portion opposite to the convex portion is formed in the first bottom portion, the concave portion having an opening that is open toward the convex portion, and the convex portion is inserted into the concave portion by passing through the opening;
• wherein the first bearing seat comprises a first side wall portion and a second side wall portion, the first side wall portion and the second side wall portion are fixed to the first bottom portion and are spaced in the width direction, and the second bearing seat is located between the first side wall portion and the second side wall portion;
• and
• the bearing seat assembly further comprises a first stopper and a second stopper, the first stopper is clamped solely and directly between the second bearing seat and the first side wall portion, and the second stopper is clamped solely and directly between the second bearing seat and the second side wall portion;
• wherein the radial bearing is mounted in the second bearing seat, an outer ring of the radial bearing is fixed to the second bearing seat, and the shaft is inserted into a bearing hole of the radial bearing and is fixed to an inner ring of the radial bearing.
