Abstract
Official abstract text for this publication.
An object is to provide a mounting structure of a bearing member which enables size and weight reduction of entire apparatus and also contributes to cost reduction thereof. The mounting structure of a bearing member includes: a bearing member for supporting a rotary shaft; a case member to which the bearing member is mounted; and a mounting plate for clamping the bearing member in an axial direction of the rotary shaft in conjunction with the case member, wherein the mounting plate includes a mounting portion of a counter member which is mounted to the case member and clamps the case member in the axial direction in conjunction with the counter member.
First claim
Opening claim text (preview).
The invention claimed is: 1. A mounting structure of a bearing member comprising: the bearing member for supporting a rotary shaft; a case member to which the bearing member is mounted, wherein the case member includes a worm shaft rotatably mounted to the case member and a worm gear which meshes with the worm shaft, and the rotary shaft rotates as the worm gear rotates; and a mounting plate for clamping the bearing member in an axial direction of the rotary shaft in conjunction with the case member, wherein the mounting plate includes a mounting portion of a counter member which is mounted to the case member, and clamps the case member in the axial direction in conjunction with the counter member. 2. The mounting structure of a bearing member according to claim 1 , wherein a material strength of the mounting plate is higher than a tensile strength of the case member. 3. The mounting structure of a bearing member according to claim 1 , wherein a shaft end of the rotary shaft is inserted into and fixed to a table member to which the worm gear is mounted. 4. The mounting structure of a bearing member according to claim 3 , wherein an outer ring of the bearing member is clamped by the mounting plate and the case member, and an inner ring of the bearing member is clamped by the table member and a holding plate fastened to the table member. 5. A speed reducing apparatus, comprising: a bearing member for supporting a rotary shaft via a table member; a case member to which the bearing member is mounted, wherein the case member includes a worm shaft rotatably mounted to the case member and a worm gear which meshes with the worm shaft, and the rotary shaft rotates as the worm gear rotates; and a mounting plate for clamping the bearing member in the axial direction of the rotary shaft in conjunction with the case member, wherein the mounting plate includes a mounting portion of a counter member which is mounted to the case member, and clamps the case member in the axial direction in conjunction with the counter member. 6. The mounting structure of a bearing member according to claim 2 , wherein a shaft end of the rotary shaft is inserted into and fixed to a table member to which the worm gear is mounted.
