Abstract
The utility model provides a tensioning device of a conveying chain. The tensioning device comprises a rack, a gear shaft arranged at the two ends of the rack, a gear connected to the gear shaft and the chain meshed with the gear. Tensioning device bodies for adjusting the degree of tightness between the chain and the gear are arranged on the two sides of the gear shaft. According to the tensioning device of the conveying chain, the degree of tightness between the gear and the chain is adjusted by changing the height of the gear shaft, the service life is long, and the safety performance is high.
Description
Technical field
The utility model is specifically related to the tightening device of transmission chain.
Background technology
The tightening device of transmission chain, it is a kind of device transmitting by gear wheel shaft and gear driven chain, conventionally when long in chain and the gear running time, due to chain and gear all some wearing and tearing to a certain extent, transmit reliability thereby reduce, under certain conditions, need the elasticity between adjusting chain and gear just can better finish the work, and in existing transmission chain device, be not easy to control the elasticity between them, the degree of tension scope regulating is smaller, and service life is short, and safety performance is low.
Summary of the invention
Technical problem to be solved in the utility model is to provide the tightening device of transmission chain, and this structure is carried out the degree of tension of adjusting gear and chain by changing the height of gear wheel shaft, long service life, and safety performance is high.
For solving above-mentioned existing technical matters, the utility model adopts following scheme: the tightening device of transmission chain, comprise frame, be erected at frame two ends gear wheel shaft, be connected to the gear on gear wheel shaft, the chain engaging with gear, described gear wheel shaft both sides are provided with the tightening device of elasticity between adjusting chain and gear.
As preferably, described tightening device comprises the axle sleeve that is socketed on gear wheel shaft, be fixed on screw rod on adapter plate of axle sleeve lower end cross-under, be located at the first nut for standing screw on screw rod, this structure tightening device carrys out the height of regulating tooth wheel shaft by changing the upper-lower position of screw rod, thereby changes elasticity between chain and gear.
As preferably, on described screw rod, be positioned at adapter plate lower end and be provided with spring, described screw rod lower end is provided with the second nut for fixing spring, this structure adapter plate lower end is provided with spring, make spring compacted by turning the second nut, avoid screw rod loosening up and down, further strengthen the stability of screw rod.
As preferably, described axle sleeve is provided with the setting nut that regulates elasticity between axle sleeve and gear wheel shaft, this structure is owing to having certain gap between axle sleeve and gear wheel shaft, in the time that screw rod is tightened, gear wheel shaft is subject to a pressure, when pressure is excessive or can finely tune setting nut when too small, reach elasticity coefficient more accurately, extended the service life of screw rod and nut simultaneously.
As preferably, described gear adopts two, and this structure adopts two gears, and Comparision is stable.
Beneficial effect:
The utility model adopts technique scheme that the tightening device of transmission chain is provided, and this structure is carried out the degree of tension of adjusting gear and chain by changing the height of gear wheel shaft, long service life, and safety performance is high.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the tightening device of transmission chain, comprise frame 1, be erected at frame 1 two ends gear wheel shaft 2, be connected to the gear 3 on gear wheel shaft 2, the chain 4 engaging with gear 3, described gear wheel shaft 2 both sides are provided with the tightening device 5 of elasticity between adjusting chain 4 and gear 3.Described tightening device 5 comprises the axle sleeve 51 that is socketed on gear wheel shaft 2, be fixed on screw rod 53 on adapter plate 52 of axle sleeve 51 lower ends cross-under, be located at the first nut 54 for standing screw 53 on screw rod 53.On described screw rod 53, be positioned at adapter plate 52 lower ends and be provided with spring 57, described screw rod 53 lower ends are provided with the second nut 56 for fixing spring 57.Described axle sleeve 51 is provided with the setting nut 55 that regulates elasticity between axle sleeve 51 and gear wheel shaft 2.Described gear 3 adopts two.
When practical operation, tightening device 5 carrys out the height of regulating tooth wheel shaft 2 by changing the upper-lower position of screw rod 53, thereby change elasticity between chain 4 and gear 3, on screw rod 53, be positioned at adapter plate 52 lower ends and be provided with spring 6, make spring 57 compacted by turning the second nut 56, avoid screw rod 53 loosening up and down, further strengthen the stability of screw rod 53, this structure is owing to having certain gap between axle sleeve 51 and gear wheel shaft 2, in the time that screw rod 53 is tightened, give gear wheel shaft 2 one pressure, when pressure is excessive or can finely tune setting nut 55 when too small, reach elasticity coefficient more accurately, extended the service life of screw rod 53 and nut 55 simultaneously, adopt two gears 3, Comparision is stable, this structure is carried out the degree of tension of adjusting gear and chain by changing the height of gear wheel shaft, long service life, safety performance is high.
Specific embodiment described herein is only to the explanation for example of the utility model spirit, the utility model person of ordinary skill in the field can make various modifications or supplements or adopt similar mode to substitute described specific embodiment, but can't depart from spirit of the present utility model or surmount the defined scope of appended claims.
