Abstract
Abstract The invention relates to a transmission joint with bellows-type elastomer dust-guard comprising an inner element rigid with a first shaft and drivingly engaged for rotation with an outer element rigid with a second shaft, the bellows dust-guard comprising end collars adapted to be fastened by clamping the one to the outer element and the other to the first joint shaft. According to the invention, the inner space of the joint and dust-guard assembly is adapted to be connected to the surrounding atmosphere by means of a split resilient ring interposed between the first shaft and the corresponding end collar, and so shaped as to permit the passage of air along this shaft in the clamped collar condition.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
113 words
A transmission joint with a bellows-type dust-guard of elastomer, the joint comprising an inner element rigid with a first shaft and drivingly engaging for rotation an outer element rigid with a second shaft, said bellows dust-guard comprising end collars fastened by clamping means, the one to said outer element and the other to said first joint shaft, means being provided for connecting the inner space of the joint and dust-guard assembly to the surrounding atmosphere, said connecting means comprising a split resilient ring interposed between said first shaft and the corresponding end collar, and so shaped as to provide a free air passage along said shaft when the collar is clamped in position.
Claim 2
Dependent Claim
113 words
A transmission joint with a bellows-type dust-guard of elastomer, the joint comprising an inner element rigid with a first shaft and drivingly engaging for rotation an outer element rigid with a second shaft, said bellows dust-guard comprising end collars fastened by clamping means, the one to said outer element and the other to said first joint shaft, means being provided for connecting the inner space of the joint and dust-guard assembly to the surrounding atmosphere, said connecting means comprising a split resilient ring interposed between said first shaft and the corresponding end collar, and so shaped as to provide a free air passage along said shaft when the collar is clamped in position.
Claim 3
Dependent Claim
27 words
A transmission joint with bellows dust-guard according to claim 1, wherein the split ring comprises inner end shoulders extending on either side of the corresponding end collar.
Claim 4
Dependent Claim
79 words
A transmission joint with bellows dust-guard according to claim 1, wherein the ring comprises along its slit two lips adapted to overlap each other in the clamped condition of the ring on the shaft, the first lip resulting from an inner marginal clearance and the second lip from an outer marginal clearance adjacent said slit, and such that said lips overlap each other only partially, at least on the inner side of the ring, to provide said air passage.
Claim 5
Dependent Claim
25 words
Transmission joint with bellows dust-guard according to claim 1, wherein said air passage consists of a groove formed on the inner surface of the ring.
Claim 6
Dependent Claim
52 words
Transmission joint with bellows dust-guard according to claim 4, wherein said groove is formed opposite the ring slit, and that the ring has its outer circumference disposed eccentrically in relation to the inner circumference so that its thickness is greater in the area of said groove than in that of said slit.
