Abstract
The invention relates to a shock absorbing mechanism for a step chain, and relates to the technical field of escalators. The shock absorbing mechanism for the step chain comprises a shaft pipe, step sprockets and a sprocket for double chain, wherein the two ends of the shaft pipe are provided with step sprockets in the length direction, and the sprocket for double chain is arranged on the step sprocket; and a shock absorbing ring is arranged in a toothed groove of the step sprocket. The shock absorbing mechanism for the step chain has the advantages of simple structure, avoidance of collision of the step chain and the step sprockets, and prolonged service life of an escalator step.
Description
Technical field
The present invention relates to the technical field of staircase.
Background technology
Present stair step is to arrange ladder sprocket wheel at the two ends of central siphon, arranges duplex chain wheel on the ladder sprocket wheel, and staircase is when normal operation, and step chains is engaged in the ladder sprocket wheel motion.Step chains contacts with collision in the ladder sprocket wheel engagement operation process and produces larger noise, and the sleeve of step chains and the teeth groove of ladder sprocket wheel are caused wearing and tearing.Reduced the service life of staircase.
Summary of the invention
The object of the invention provides a kind of simple in structure, avoids the collision of step chains and ladder sprocket wheel, prolongs the stair step step chains damping in service life.
A kind of step chains damping comprises central siphon, ladder sprocket wheel, duplex chain wheel, and ladder sprocket wheel is arranged at the two ends of central siphon length direction, arranges duplex chain wheel on the ladder sprocket wheel, arranges shock ring in the teeth groove of above-mentioned ladder sprocket wheel.
The present invention arranges minor sprocket at central siphon.
The present invention installs shock ring in the teeth groove of ladder sprocket wheel after, step chains contacts with the shock ring collision, has effectively reduced noise, has improved simultaneously the service life of step chains and ladder sprocket wheel, has prolonged simultaneously the service life of stair step.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing technical scheme of the present invention is elaborated:
As shown in Figure 1, a kind of step chains damping comprises central siphon 1, ladder sprocket wheel 2, duplex chain wheel 3, and ladder sprocket wheel 2 is arranged at the two ends of central siphon 1 length direction, arranges duplex chain wheel 3 on the ladder sprocket wheel 2, arranges shock ring 4 in the teeth groove of above-mentioned ladder sprocket wheel 3.
As shown in Figure 1, arrange minor sprocket 5 on the central siphon 1 of the present invention.
Shock ring of the present invention is to make with the EU material, has preferably the characteristics such as elasticity, wear-resisting, fuel resistance, hydrolysis.Shock ring is installed in the teeth groove of ladder sprocket wheel, has played the effect of bumper and absorbing shock.
