Abstract
Belt guide members guide an upper belt and a lower belt for closing a slit of a cylinder tube. Belt holder sections for the upper belt and belt separators for separating the upper belt and the lower belt from each other are integrally formed in the belt guide members. Bearings for positioning a slider are disposed to engage with the belt guide members.
Claims8
A belt guide mechanism for guiding a first belt and a second belt for closing a slit of a body of a pressure fluid-driven apparatus, said slit extending in an axial direction of a cylinder tube, said belt guide mechanism comprising:
- a guide body;
- a first guide member which engages with engaging grooves of said guide body and which has a belt separator for separating said first belt and said second belt from each other and a holder section for pressing said first belt toward said second belt, said belt separator and said holder section being integrally formed in said first guide member;
- and
- a second guide member which is disposed opposite to said holder section of said first guide member and which guides said second belt.
A belt guide mechanism for guiding an upper belt and a lower belt for closing a slit which extends in an axial direction of a cylinder tube,
- said belt guide mechanism being disposed in a rodless cylinder for moving a slider in said axial direction of said cylinder tube together with said piston, said piston being moved along a bore of said cylinder tube by pressure fluid supplied into said cylinder tube,
- said belt guide mechanism comprising:
- a guide body which is connected to said piston and which moves together with said piston;
- a pair of belt guide members which engage with engaging grooves of said guide body facing a space between said slider and one surface of said cylinder tube having said slit, said pair of belt guide members having a pair of belt separators for separating said upper belt and said lower belt from each other and belt holder sections for pressing said upper belt toward said lower belt, and said pair of belt separators and said belt holder sections being integrally formed in said pair of belt guide members;
- and
- a pair of wear rings which are disposed on said piston opposite to said belt holder sections of said belt guide members and which guides said lower belt.
