Abstract
The utility model relates to an unclosed chain driving protector. An arc-shaped protecting cover is installed at the top part of a chain wheel, both ends of the arc-shaped protecting cover are fixed on a cross beam, and a chain shifting card is installed at the position of the cross beam, which is corresponding to the tangent position of the inner diameter of the chain wheel. Slippage and winding phenomena during the non-closed chain driving can be thoroughly eliminated by the utility model which has the advantages of simple structure and low cost.
Description
The utility model relates to a kind of non-enclosed chain-driven protective equipment.
Because chain-driven has lot of advantages, therefore application is quite extensive in mechanical industry, but because of present driving mechanism is non-enclosed chain-driven, is prone to chain and jumps phenomenons such as tooth, winding, thus the mechanical accident of causing.People had once adopted some ways, and as at its B end suspension heavy weight or hang up spring etc., but effect is all undesirable.
The purpose of this utility model provides a kind of protective equipment that can thoroughly remove non-enclosed chain-driven jumping tooth, wrapping phenomena.
Chain-driven protective equipment of the present utility model is to adorn an arc guard shield at the top of sprocket wheel, and the guard shield two ends are fixed on the crossbeam, and on the crossbeam with sprocket wheel internal diameter tangent position corresponding position, the chain that a working surface is housed is arc is dialled card.When chain, sprocket teeth wearing and tearing or precision are not high, slippage phenomenon very easily appears, this moment, guard shield forced to cover chain, eliminate slippage phenomenon, if chain, pitch of chain wheel have error, when chain had the higher machine oil of viscosity or foreign matter is arranged, chain can touch sprocket wheel and together rotate (promptly twine), and chain was dialled card and can be pushed chain open to make it nature sagging this moment.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model partial structurtes schematic representation.
1, guard shield 2, sprocket wheel 3, chain are dialled card
4, chain 5, crossbeam
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in the figure, at sprocket wheel 2 tops one arc guard shield 1 is housed, guard shield 1 two ends are fixed on the crossbeam 5, and in crossbeam 5 and sprocket wheel 2 internal diameter tangent position corresponding positions, an arc-shaped chain are housed dial card 3.When sprocket wheel 2 clockwise rotated, A end (end bears a heavy burden) rose, and B end (broken end) descends, and took turns odontotripsis or precision when not high when chain 4 sprocket wheels 2, slippage phenomenon very easily occurred; This moment, guard shield 1 pressure covered chain 4, eliminated slippage phenomenon; If chain 4, sprocket wheel 2 pitches have error, when chain 4 had the higher machine oil of viscosity or foreign matter is arranged, chain 4 can touch sprocket wheel 2 and together rotate, and chain was dialled card 3 and can be pushed chain 4 open and make it sagging naturally this moment.
Protective equipment of the present utility model can thoroughly be eliminated the phenomenon that tooth, winding are jumped in non-enclosed chain-driven, and simple in structure, and cost is low.
Claims (3)
1, a kind of non-enclosed chain-driven protective equipment is characterized in that at the top of sprocket wheel one arc guard shield being housed, and the guard shield two ends are fixed on the crossbeam, a chain also is housed on crossbeam dials card.
2, chain-driven protective equipment according to claim 1 is characterized in that chain is dialled to be installed on the crossbeam and sprocket wheel internal diameter tangent position corresponding position.
