Abstract
A hoisting drum and fixing equipment of reel drum hub is composed of a reel drum, the reel drum hub, a clamping ring, an elastic diagonal clamping ring, bolts, etc. Adopting axial displacement of the clamping ring, the utility model enables the pinched end face to create a mechanical holding mode of sagittal frictional force. Thus, the utility model has the advantages of reliable fixing, compact and simple structure, convenient mounting or dismounting and maintenance, long service life and favorable for safety in production.
Description
It is mechanical that the utility model belongs to, and particularly relates to a kind of elevator reel and reel hub anchor fitting.
In the existing winch product, all adopt key to fix and bolt, adopt these fixed forms often to cause the shear fails phenomenon, the while product structure is more complicated also, uses inconvenience, is unfavorable for safety in production.
The purpose of this utility model provides a kind of reel and reel hub anchor fitting, the mechanical fastening system of this novelty, simple in structure, compactness, fixing reliable and secure, long service life, no matter be to do positive and negative running at the reel that has load, still when positive and negative running, stop suddenly, reel and reel hub are fixed as one, simultaneously convenient maintenance.
The utility model is achieved in that by driving system and is connected with the reel hub that reel ends has one section oblique convex shoulder, has several radially grooves on this oblique convex shoulder.Reel is enclosed within on the convex shoulder of reel hub, the oblique snap ring of elasticity is placed between oblique convex shoulder of reel end face and the trim ring inward hole slope, pass with several bolts and to go up on number holes and trim ring garden week several tapped bore reel hub garden week and tighten regularly, make trim ring make longitudinal travel to the reel hub.In axial displacement process, the trim ring inward hole slope produces radial frictional force fits on the oblique convex shoulder of reel the oblique snap ring of several pieces elasticity equably, forces the original radial dimension in the oblique convex shoulder of reel place to shrink, and reaches closely to be fixed as one with the reel hub.
With reference to the accompanying drawings the utility model is done to describe further.
1. oblique snap ring 3. trim rings of reel 2. elasticity 4. reel hubs 5. bolts
Fig. 1 is the planar view of lifting drum and reel hub anchor fitting.
With reference to accompanying drawing, driving system is connected with reel hub 4, and trim ring 3 is enclosed within on the reel 1, and the oblique snap ring 2 of elasticity is placed on the reel 1 oblique convex shoulder, passes the hole of reel hub 4 garden on week by several bolts 5 and is connected with trim ring 3 tapped bore of garden on week.When tighting a bolt regularly, trim ring 3 is made longitudinal travel to reel hub 4.Trim ring 3 inward hole slope that move past in the journey on the throne produce radial frictional force, and the oblique snap ring 2 of several pieces elasticity is fitted on the reel 1 oblique convex shoulder equably, and the original radial dimension that forces reel 1 to have the oblique convex shoulder place of radial slot is made the radial shrinkage after stressed.At this moment, reel 1 endoporus and the reel hub 4 that have an oblique convex shoulder of radial slot closely is fixed as one.
The utility model is owing to adopt the longitudinal travel trim ring to produce the fixed form that radial frictional force makes reel and reel hub, so complete machine is fixing reliable and secure, and long service life.Equally, anchor fitting is because simple, and reliably energy and driving system combine, and make complete machine structure compacter, and volume is littler, is convenient to install and use.Load value is not more than the radial frictional force of reel and reel hub on the reel, and reel and reel hub are closely to be fixed as one, and do not produce the slide relative phenomenon.If the load value on the reel during greater than the radial frictional force of reel and reel hub, only needs to adjust axial displacement or strengthen oblique convex shoulder width, make the radial friction sheet increase of reel and reel hub, everything all favourable safety in production.
Claims (1)
- A kind of lifting drum and reel hub anchor fitting of forming by reel, reel hub, trim ring, the oblique snap ring of elasticity, bolt etc., it is characterized in that: the reel hub is connected by bolt with trim ring, reel is enclosed within on the reel hub convex shoulder, and the oblique snap ring of elasticity is placed between the oblique convex shoulder and trim ring inward hole slope that the reel end has groove.
