Abstract
The utility model relates to a tensioning device with a damper, which comprises a piston rod (1), a cylinder (2) and a spring seat (3). The piston rod (1) is inserted into a cavity of the cylinder (2), the spring seat (3) is fixed to the other end of the cylinder (2), and a tensioning spring (4) is sleeved on the periphery of the cylinder (2). The tensioning device with the damper is characterized in that the damper (5) is arranged in a cavity of the piston rod (1). The tensioning device is provided with the damper, and a pressure difference formed on two sides of the damper relieves direct impact of the spring and buffers a tensioning wheel better, so that the tensioning wheel runs more stably, while the service life of the spring is prolonged.
Description
(1) technical field
The utility model relates to a kind of belt tensioner with the buffering damping, is mainly used in the caterpillar track travelling engineering machinery.
(2) background technique
The tradition crawler travel machinery impact force of expansion tightening wheel in the process of walking mainly converts the elastic force of spring into through the impact force of tensioner spring handle expansion tightening wheel, thereby plays buffer function.Because the impact force that receives is all passed to spring, cause the working life of spring relatively poor, need often to change and detect, increased workload and cost of production greatly.
(3) summary of the invention
The purpose of the utility model is to overcome above-mentioned deficiency, and a kind of belt tensioner with the buffering damping is provided, and has significantly reduced the direct impact of spring, improves the working life of spring.
The purpose of the utility model is achieved in that a kind of belt tensioner with the buffering damping; It comprises piston rod, oil cylinder and spring pedestal; Said piston rod inserts in the chamber of oil cylinder; Said spring pedestal is fixed in an end of oil cylinder, is with the tensioner spring in the periphery of said oil cylinder, in the chamber of said piston rod, is provided with the buffering damping.
Compared with prior art, the beneficial effect of the utility model is:
The utility model is because the existence of buffering damping makes the damping both sides produce a pressure difference, and this pressure difference has played the direct impact that slows down spring, and expansion tightening wheel is also had better buffer function, and it is more steady to make it walking, and the life-span of having improved spring.

Piston rod 1
Spring pedestal 3
Tensioner spring 4
(5) embodiment
Referring to Fig. 1-Fig. 2; The utility model relates to a kind of belt tensioner with the buffering damping; It comprises piston rod 1, oil cylinder 2 and spring pedestal 3, and said piston rod 1 inserts in the chamber of oil cylinder 2, and said spring pedestal 3 is fixed in an end of oil cylinder 2; Be with tensioner spring 4 in the periphery of said oil cylinder 2, in the chamber of said piston rod 1, be provided with buffering damping 5.
When expansion tightening wheel is hit; Fluid gets in the chamber of piston rod in the chamber of oil cylinder, because the existence of buffering damping makes the damping both sides produce a pressure difference; This pressure difference has played the direct impact that slows down spring; Expansion tightening wheel is also had better buffer function, and it is more steady to make it walking, and the life-span of having improved spring.
Claims (1)
- One kind with the buffering damping belt tensioner; It comprises piston rod (1), oil cylinder (2) and spring pedestal (3); Said piston rod (1) inserts in the chamber of oil cylinder (2); Said spring pedestal (3) is fixed in an end of oil cylinder (2), is with tensioner spring (4) in the periphery of said oil cylinder (2), it is characterized in that in the chamber of said piston rod (1), being provided with buffering damping (5).
