Abstract
The utility model provides a chain tensioning device for a chain and chain wheel transmission mechanism, which is simple in structure and convenient to use. The chain tensioning device for the chain and chain wheel transmission mechanism comprises a rotary shaft with a chain wheel, wherein two ends of the rotary shaft are arranged on a bearing seat; the bearing seat is arranged on a rack in a sliding manner in a direction perpendicular to an axial direction of the rotary shaft; a fixing seat matched with a stud is arranged on the rack; and the stud is connected with the bearing seat by a screw pair.
Description
Technical field
The utility model relates to a kind of chain stretching device of chain sprocket driving mechanism.
Background technique
The sprocket chain strip transmission mechanism is generally adopted in the driving of network chain, and along with the reasons such as wearing and tearing of chain, chain can extend to some extent.Therefore generally all need chain stretching device that chain is carried out tensioning.Present chain stretching device, complex structure is adjusted loaded down with trivial details.
Summary of the invention
The purpose of this utility model provides a kind of chain stretching device of chain sprocket driving mechanism simple in structure, easy to use.
The chain stretching device of this chain sprocket driving mechanism, comprise the rotating shaft that sprocket wheel is set, the two ends of rotating shaft are arranged on the bearing support, bearing support is arranging on the frame perpendicular to the axial direction slip of rotating shaft, be provided with the fixed base that cooperates with double-screw bolt in frame, double-screw bolt is connected with screw pair with bearing support.
Above-mentioned chain stretching device is provided with Compress Spring between bearing support and fixed base.
The beneficial effects of the utility model: during use, rotate double-screw bolt, double-screw bolt drives bearing support by screw pair and slides, and rotating shaft is namely moved in the axial direction of vertical rotation axis under the drive of bearing support, thereby the position of the sprocket wheel in the change rotating shaft, thereby the chain that tensioning cooperates with sprocket wheel.To the bearing support applied thrust, more laborsaving when regulating by Compress Spring.
Description of drawings
Fig. 1 is the schematic diagram of chain stretching device of the chain sprocket driving mechanism of network chain.
Embodiment
Chain stretching device referring to the chain sprocket driving mechanism of network chain shown in Figure 1, comprise the rotating shaft 1 that sprocket wheel is set, the two ends of rotating shaft are arranged on the bearing support 2, and bearing support is provided with fixed base 6 arranging on the frame 4 by guide rail 3 slips on the direction axial perpendicular to rotating shaft in frame.Fixed base 6 and double-screw bolt 5 are connected with screw pair, and double-screw bolt is connected with screw pair with bearing support.Between bearing support and fixed base, be provided with Compress Spring 7.
