Abstract

The utility model relates to a roller assembly limiting mechanism. The roller assembly limiting mechanism comprises a fixed shaft, and two ends of the fixed shaft are fixed on side plates. The roller assembly limiting mechanism is characterized in that two ends of the fixed shaft are respectively provided with a limiting mechanism, bearings are arranged on inner sides of the limiting mechanisms, and rollers are respectively arranged on the bearings. Each limiting mechanism comprises two semicircular fixed sleeves, and the two fixed sleeves are connected into a whole through bolts and sleeved on the fixed shaft. The roller assembly limiting mechanism can meet limiting of the rollers in the axial direction, prevent the bearings inside the rollers from shifting in the axial direction when the rollers bear large axial load and protect the rollers and the bearings inside the rollers. By means of the roller assembly limiting mechanism, the purposes of replacing the rollers and the bearings quickly and reducing machining amount of shafts at the same time can be achieved.

Description

The roll assembly stop gear

Technical field

The utility model relates to a kind of roll assembly stop gear, and especially a kind of device for spacing roller left and right directions belongs to mechanical automation conveyer technical field.

Background technology

The roll assembly structure is the class conveyer in the conveyer system; the general load transfer device that is used on the car production shop production line; to carry along radially direction at conveying roller on the equipment; during power on roller bears axially; as: the fork truck of inside, workshop, logistic car by the time can pair of rollers produce axial load; the roller stop gear can be offset axial load; the axial motion that stops roller; therefore the bearing of protection roller and roller inside needs a kind of mechanism that can prevent the roller axial motion of design.Existing position limiting structure is that a kind of gauge member is the axle elastic circlip, and this jump ring can bear less axial load, and this jump ring is being subject to impacting suddenly or effect lower time of larger load will be cracked, has so just lost the meaning of roller axial limiting.

Summary of the invention

The purpose of this utility model is to overcome the deficiencies in the prior art; a kind of roll assembly stop gear is provided, can satisfies roller axial spacing, when roller bears larger axial load; prevent the bearing of roller inside at axial motion, the bearing of protection roller and roller inside.

The technical scheme that provides according to the utility model, described roll assembly stop gear comprises that two ends are fixed on the anchor shaft on the other plate, and feature is: the two ends at described anchor shaft are respectively arranged with limit assembly, bearing is installed respectively in inboard at limit assembly, and roller is set respectively on bearing.

Described limit assembly comprises two semi-round fixed covers, and two fixed covers are as a whole by the screw connection, are set on the anchor shaft.

Roll assembly stop gear described in the utility model can satisfy roller axial spacing, when roller bears larger axial load, prevents the bearing of roller inside at axial motion, the bearing of protection roller and roller inside; Can reach quick-replaceable bearing, roller after the utility model uses, reduce the processing capacity of axle simultaneously.

Fig. 2 is the structural representation of limit assembly of the present utility model.

Fig. 3 is the birds-eye view of Fig. 1.

The specific embodiment

The utility model is described in further detail below in conjunction with concrete accompanying drawing.

Such as Fig. 1～shown in Figure 3: the roll assembly stop gear comprises other plate 1, limit assembly 2, bearing 3, roller 4, anchor shaft 5, fixed cover 6, screw 7 etc.

The utility model comprises that two ends are fixed on the anchor shaft 5 on the other plate 1, be respectively arranged with limit assembly 2 at the two ends of described anchor shaft 5, bearing 3 is installed respectively in inboard at limit assembly 2, roller 4 is set respectively on bearing 3, limit assembly 2, bearing 3 and roller 4 integral body be placed on do on the anchor shaft 5 as a whole;

As shown in Figure 2, it is as a whole that described limit assembly 2 comprises that 6, two fixed covers 6 of two semi-round fixed covers are connected by screw 7, is set on the anchor shaft 5, spacing thereby the axial motion of pair of rollers 4 carries out;

Wherein fixed cover of described two first circular fixed covers 6 is provided with the fixing tapped bore of bolt, on the semicircle fixed cover in addition unthreaded hole is set, can utilize like this screw 7 that two semicircle fixed covers are connected as a whole fixed cover, fixed cover is stuck on the anchor shaft on roller next door again.

Working process of the present utility model is as follows: when roller 4 is subject to external force shown in the direction of arrow among Fig. 1 during normal operation; roller 4 can produce axial motion along anchor shaft 5 because being subject to external force; limit assembly 2 will stop this motion of roller 4; prevent that bearing 3 from spinning off from roller 4 inside, thereby finish the protection of pair of rollers 4, bearing 3.
