Abstract
The utility model discloses a kind of chain support device, include: chain roller supporting wheel, two supporting wheels for support chains both sides, described chain roller supporting wheel is set on chain roller back shaft, the supporting wheel of described both sides is set on supported on both sides axle respectively, described chain roller back shaft, supported on both sides axle are fixed on bracing strut, and described bracing strut is fixed on fixing frame.Chain roller supporting wheel of the present utility model rotates and is used for support chains roller on back shaft, and two supporting wheels of both sides rotate and are used for preventing chain from departing from chain roller supporting wheel on back shaft; Friction can be reduced, the working life of chain and support device can be extended again, ensure that the stationarity in chain.
Description
Technical field
The utility model belongs to the device of a kind of support chains in mechanical field.
Background technique
The chain used at present supports, and the chain be generally made up of each parts such as bracket, bolt, nylon blocks supports, and object in chain movement process, plays picking-up chain make it not sagging.But because nylon block can not rotate, the frictional force between chain roller and nylon block is comparatively large, both worn chain of long duration, wear and tear again nylon block, and chain roller likely departs from nylon block and causes a problem be unable to hold out simultaneously, affects working efficiency.
Model utility content
The purpose of this utility model is to provide a kind of chain support device, can reduce friction, prevents chain from departing from fixing frame, extends the working life of chain.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of chain support device, include: chain roller supporting wheel, two supporting wheels for support chains both sides, described chain roller supporting wheel is set on chain roller back shaft, the supporting wheel of described both sides is set on supported on both sides axle respectively, described chain roller back shaft, supported on both sides axle are fixed on bracing strut, and described bracing strut is fixed on fixing frame.
Described fixing frame is the bending steel plate with two bending edges, is fixed with stiffening rib bottom bending steel plate.
Described chain roller supporting wheel, be nylon supporting wheel for two supporting wheels of support chains both sides.
The advantage that the utility model has is:
Chain support device described in the utility model includes chain roller supporting wheel, two supporting wheels for support chains both sides, wherein chain roller supporting wheel rotates and is used for support chains roller on back shaft, and two supporting wheels of both sides rotate and are used for preventing chain from departing from chain roller supporting wheel on back shaft; Friction can be reduced, the working life of chain can be extended again, ensure that the stationarity in chain.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
As shown in Figure 1, the utility model provides a kind of chain support device, include chain roller supporting wheel 1, two supporting wheels 21,22 for support chains both sides, described chain roller supporting wheel 1 is set on chain roller back shaft 3, the supporting wheel 21,22 of described both sides is set on supported on both sides axle 41,42 respectively, described chain roller back shaft 3, supported on both sides axle 21,22 are fixed on bracing strut 7, and described bracing strut 7 is fixed on fixing frame 5.
Wherein fixing frame 5 can adopt bending steel plate, has two bending edges 51,52, and bending edge 51,52 is for rationally fixing fixing frame 5; Be fixed with stiffening rib 53 bottom bending steel plate, strengthen the supporting effect of fixing frame.
Wherein chain roller supporting wheel 1, nylon supporting wheel can be adopted for two supporting wheels 21,22 of support chains both sides, rub little, noise is little.
The utility model in use, the bending edge 52,52 of fixing frame 5 is bolted on suitable place, bracing strut 7 is bolted on place suitable on fixing frame 5 simultaneously, the below of the chain roller 6 chain roller supporting wheel 1 being arranged on will support, then supporting wheel 1 coordinates with chain roller 6 and operates under the effect of back shaft 3, simultaneously two supporting wheels 21,22 of both sides are in two side contacts of chain, rotate under the effect of back shaft 41,42 thus the friction of reduction chain, prevent chain from departing from supporting wheel 1, chain can be made to operate more stably.Chain support device described in the utility model can reduce the friction between chain and support device, extends the working life of chain and support device, ensures chain smooth running.
Claims (3)
