Abstract
The utility model discloses a chain wheel movable spoke, relating to a mechanical drive device. In the existing product, as chain wheels of two ends of a driving shaft are both fixed on the driving shaft and the thermal expansion speed of the driving shaft is slower than that of chains, the chains and the chain wheels are misplaced to cause the chains to leave from the chain wheels, and accidents occur. The utility model is characterized in that two ends of a driving shaft are provided with chain wheelchocks which are fixedly connected with chain wheels, and corresponding key grooves are arranged between the chain wheelchocks and the driving shaft. Linkage flat keys are arranged in the key grooves, and a translation space exists between at least one key groove and the flat key at one end. The translation space is fitted with the difference range of the thermal expansion speed of the pedrail chains and the driving shaft. The thermal expansion of the chains drives the chain wheelchocks to translate outwards to avoid misplacement and prevent the chains from leaving from the chain wheels. The chain wheelchocks and spoke seats of two end ports of the spoke are in an integral structure, so the structure of equipment is simplified.
Description
[technical field]
The utility model relates to mechanical transmission, more particularly, is that a kind of track chain that can prevent takes off the spoke of chain.
[background technique]
Spoke is the drive unit of chain type crawler belt, the driving shaft rotating band movable sprocket of spoke, and sprocket wheel drives track chain, and then driving track.When the drive unit of this kind structure was applied to dyeing apparatus, its initial temperature was when normal temperature, and chain is handled steam box and heated down fast and understand lateral expansion through whole the dying that is positioned at its below.Because the sprocket wheel of both ends of main drive shaft all is fixed on the driving shaft, and the relative chain heat expansion of driving shaft speed is slow, cause chain to follow sprocket wheel to misplace, often make chain break away from sprocket wheel, have an accident, not only can incur loss through delay production, and sprocket wheel will can't use because of impaired because chain breaks away from afterwards, cause cost of production to increase, even more serious then will cause security incident.In addition, existing spoke is arranged the spoke seat branch of chain catch and port usually.
[model utility content]
The purpose of this utility model is at above-mentioned deficiency, provides a kind of track chain that prevents to take off the movable spoke of sprocket wheel of chain, and further purpose is that the structure of spoke is simplified.
The technical solution of the utility model is as follows: the movable spoke of a kind of sprocket wheel, comprise driving shaft, both ends of main drive shaft is provided with the sprocket wheel shelves, is provided with corresponding keyway between the affixed sprocket wheel on the sprocket wheel shelves, sprocket wheel shelves and driving shaft, be provided with the interlock flat key in the keyway, leave the translation spacing between the keyway of at least one end and flat key, the gap scope of translation spacing and track chain and driving shaft thermal expansion is suitable, and the chain heat expansion drives the outside translation of sprocket wheel shelves, avoid misplacing, prevent that chain from taking off chain.
The described spoke end sprocket wheel shelves formation activity shelves that leave the translation spacing, the other end is fixed on the driving shaft sprocket wheel shelves of this end by a perpendicular pin, forms fixing shelves, limits its translation, one end can satisfy the trace that extends out because of expansion and adjust requirement, guarantees the reliability of spoke transmission after proper functioning.
Described driving shaft outer wall is provided with the wheel radial canal, and the first-class distance of wheel radial canal is provided with the spoke shelves, and the spoke blade is set on the spoke shelves, and being positioned at the middle spoke shelves of spoke is the folk art term structure, and the spoke blade has lower dent at the folk art term gap location.
Described spoke blade is made by corrosion resistant plate, can guarantee equipment intensity, the corrosion resistance under the high-temperature work environment.
The spoke seat of described sprocket wheel shelves and spoke two-port is an integral structure, simplified structure, easy disassembly.
Described integral structure is sprocket wheel shelves and the welding of spoke seat or is both one foundry goods.
Described translation spacing be 3 millimeters to 8 millimeters, according to test, the dislocation cause of expanding is little, this size is fit to actual demand.
Compared with prior art, outstanding advantage of the present utility model is: the sprocket wheel shelves of spoke one end are movable, combine with driving shaft by flat key, leave the translation spacing between flat key and keyway, the gap scope of translation spacing and track chain and driving shaft thermal expansion is suitable, the chain heat expansion drives the outside translation of sprocket wheel shelves, has avoided dislocation automatically, prevents that effectively chain from taking off chain.The spoke seat of sprocket wheel shelves and spoke two-port is an integral structure, simplifies overall structure.
[description of drawings]
Fig. 1 is the utility model structural representation;
Fig. 2 is the enlarged view of A portion among Fig. 1;
Fig. 3 is existing spoke architecture schematic representation;
Structural representation when Fig. 4 works for the utility model.
Wherein, 1 is driving shaft, and 2 is the sprocket wheel shelves, and 3 is sprocket wheel, and 4 are the wheel radial canal, and 5 is keyway, and 6 is normal pin, and 7 is the spoke shelves, and 8 is flat key, and 9 is the spoke seat, and 10 is the spoke blade, and 11 is chain.
[embodiment]
Below in conjunction with accompanying drawing the utility model is described in detail.
Embodiment 1: referring to Fig. 1-3, the movable spoke of sprocket wheel, comprise driving shaft 1, driving shaft 1 two ends are nested with sprocket wheel shelves 2, sprocket wheel 3 is fixed on the sprocket wheel shelves 2, and spoke combines work with crawler belt, and track chain 11 is connected on the sprocket wheel 3, driving shaft 1 drives sprocket wheel shelves 2 and rotates, and the sprocket wheel 3 on the sprocket wheel shelves 2 drives track chain 11.Link by flat key 8 between sprocket wheel shelves 2 and the driving shaft 1, the one end is fixed on the driving shaft 1 by normal pin 6 can not translation, 8 of the other end keyway 5 and flat keys leave the translation spacing, sprocket wheel shelves 2 relative driving shafts 1 are movable, translation spacing and track chain 11 are suitable with the gap scope of driving shaft 1 thermal expansion, can be 3 millimeters to 8 millimeters.When cold turner is done, chain 11 at first expanded by heating extends out, driving shaft 1 then is heated to lag behind more slowly and expands, this moment, but the straight line respective distances of itself and chain 11 was adjusted in sprocket wheel 3 translations of movable end, effectively prevented because of sprocket wheel 3 maintain static cause that the two dislocation causes take off the chain phenomenon, satisfied under the requirement that chain 11 thermal expansions extend out at movable end sprocket wheel shelves 2, the other end sprocket wheel shelves 2 have been fixed on the driving shaft 1, guaranteed the stability after the equipment proper functioning.
Inboard in sprocket wheel shelves 2, on driving shaft 1, be nested with spoke seat 9, connecting wheel radial canal 4 on the periphery of spoke seat 9, sprocket wheel shelves 2 are connected as a single entity with spoke seat 9, the foundry goods that can be the welding of sprocket wheel shelves and spoke seat or be cast into for both one, the simplified apparatus structure, easy disassembly, welded spoke shelves 7 on the outer wall of wheel radial canal 4, connected spoke blade 10 on the spoke shelves 7, spoke blade 10 is made by corrosion resistant plate, can guarantee equipment intensity, corrosion resistance under the high-temperature work environment is positioned at spoke middle spoke shelves 7 and is the folk art term structure, and spoke blade 10 has lower dent at the folk art term gap location.The utility model is applicable to dyeing apparatus.
