Abstract

Abstract (57) The disclosure relates to an industrial robot free from generation of dust, which is provided with and internal space formed by covering rotating portions and contact portions of its arm members, joint members, bearing members or driving source, by the arm members, joint members, bearing members, or a cover member, or by a combination of these members, and air throttling portions provided in air passages for connecting the internal space with external air so as to separate the internal space from external air by sucking the air in the internal space. By the above air throttling portions, air within the internal space is isolated from the external air, and thus, scattering of dust from the dust generating portions toward the atmosphere is advantageously prevented.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 125 words
An industrial robot which comprises a plurality of arm members, one or a plurality of joint members, connected to each of said arm members, bearing means rotatably supporting said joint members, and a driving source for relatively rotating or pivoting said plurality of arm members through said joint members, the improvement comprising an internal space formed by covering rotating portions and contact portions of said arm members, joint members, bearing means or driving source, by said arm members, joint members, bearing means or a cover member, or by a combination thereof and air throttling portions provided in air passages for connecting said internal space with external air so as to separate said internal space from external air by sucking the air in said internal space.
Claim 2
Dependent Claim 125 words
An industrial robot which comprises a plurality of arm members, one or a plurality of joint members, connected to each of said arm members, bearing means rotatably supporting said joint members, and a driving source for relatively rotating or pivoting said plurality of arm members through said joint members, the improvement comprising an internal space formed by covering rotating portions and contact portions of said arm members, joint members, bearing means or driving source, by said arm members, joint members, bearing means or a cover member, or by a combination thereof and air throttling portions provided in air passages for connecting said internal space with external air so as to separate said internal space from external air by sucking the air in said internal space.
Claim 3
Dependent Claim 34 words
An industrial robot as claimed in Claim 1, wherein said air throttling portions are each constituted by fins having very small clearances therebetween and air expanding portions provided at front and rear sides thereof.
Claim 4
Dependent Claim 29 words
An industrial robot as claimed in Claim 1, wherein said air throttling portions are each formed by porous members having a large number of through-pores with very fine diameters.
Claim 5
Dependent Claim 32 words
An industrial robot as claimed in Claim 1, wherein said air throttling portions are integrally formed with said bearing means, and provided at a side of external air beyond said bearing means.
Claim 6
Dependent Claim 32 words
An industrial robot as claimed in Claim 2, wherein said air throttling portions are integrally formed with said bearing means, and provided at a side of external air beyond said bearing means.
Claim 7
Dependent Claim 151 words
An industrial robot which comprises a plurality of arm members, one or a plurality of joint members, connected to each of said arm members, bearing means rotatably supporting said joint members, and a driving source for relatively rotating or pivoting said plurality of arm members through said joint members, the improvement comprising an internal space formed by covering rotating portions and contact portions of said arm members, joint members, bearing means or driving source, by said arm members, joint members, bearing means or a cover member, or by a combination thereof and air throttling portions provided in air passages for connecting said internal space with external air so as to separate said internal space from external air by sucking the air in said internal space, and exhaust passages for communicating said internal space with an exhaust device, provided at part of said arm members, joint members, bearing means or cover member.
Claim 8
Dependent Claim 151 words
An industrial robot which comprises a plurality of arm members, one or a plurality of joint members, connected to each of said arm members, bearing means rotatably supporting said joint members, and a driving source for relatively rotating or pivoting said plurality of arm members through said joint members, the improvement comprising an internal space formed by covering rotating portions and contact portions of said arm members, joint members, bearing means or driving source, by said arm members, joint members, bearing means or a cover member, or by a combination thereof and air throttling portions provided in air passages for connecting said internal space with external air so as to separate said internal space from external air by sucking the air in said internal space, and exhaust passages for communicating said internal space with an exhaust device, provided at part of said arm members, joint members, bearing means or cover member.
Claim 9
Dependent Claim 34 words
An industrial robot as claimed ir Claim 6, wherein said air throttling portions are each constituted by fins having very small clearances therebetween and air expanding portions provided at front and rear sides thereof.
Claim 10
Dependent Claim 29 words
An industrial robot as claimed in Claim 6, wherein said air throttling portions are each formed by porous members having a large number of through-pores with very fine diameters.
Claim 11
Dependent Claim 32 words
An industrial robot as claimed in Claim 6, wherein said air throttling portions are integrally formed with said bearing means, and provided at a side of external air beyond said bearing means.
Claim 12
Dependent Claim 32 words
An industrial robot as claimed in Claim 7, wherein said air throttling portions are integrally formed with said bearing means, and provided at a side of external air beyond said bearing means.
