Abstract
The utility model relates to a friction type partition head sheave hub device, in particular to a friction type partition head sheave hub structure applied to a friction type lifter. The friction type partition head sheave hub structure comprises a partition head sheave (1). The head sheave (1) is installed on a head sheave shaft (2) through a bearing bush (4), a partition sleeve (5) is arranged between a head sheave hub (3) and the bearing bush (4) and the head sheave hub (3) and the partition sleeve (5) are fixedly connected to be a whole structure through a connection part. The friction type partition head sheave hub structure is characterized in that the connection part comprises a locating pin (8), a combination face of the two axial ends of the head sheave hub (3) and the partition sleeve (5) is provided with a hole for the locating pin (8) to be inserted and the head sheave hub (3) and the partition sleeve (5) are fixedly connected to be a whole through the positioning pin (8) inserted into the hole. By means of the structure, the head sheave hub is stably positioned and the overall rigidity is greatly enhanced.
Description
Technical field
The utility model relates to a kind of friction-type Subdivision head sheave device, is specifically related to a kind of friction-type Subdivision head sheave wheel hub structure for friction type winder.
Background technology
Friction type winder head sheave apparatus moves about, and what between wheel hub and day wheel shaft, mostly adopt is two halves alloyed copper tile structure; as shown in accompanying drawing 1-2; between half wheel hub 3 and halfliner 4, be conventionally also provided with the spacer 5 for reducing wearing and tearing between wheel hub 3 and bearing shell 4; lubrication channel 6 runs through wheel hub 3, spacer 5 and bearing shell 4; and form oil hole at bearing shell 4 inside face openings; for lubricating oil being injected between bearing shell 4 and day wheel shaft 2, thereby reduce friction force between the two.
In prior art, wheel hub 3 and the spacer 5 use junction of the edges of two sheets of paper screws 7 of friction-type Subdivision head sheave are located, but this structure in use, on the one hand, junction of the edges of two sheets of paper screw 7 is in stressed lower easily loosening, the landing of wheel body, now site disposal can only be permanently fixed junction of the edges of two sheets of paper screw, wheel body and spacer by welding manner, but like this, Subdivision head sheave cannot be dismantled, and loses the function of Subdivision head sheave.On the other hand, wheel body and spacer position relationship easily change, thereby likely can block lubrication channel 6, cause charging-up lubricant oil out of reach bearing shell place, cause insufficient lubrication, between bearing shell and axle, form dry friction, make head sheave apparatus in operational process, produce abnormal sound, affect the service life of head sheave apparatus.
Utility model content
The utility model is based on the problems referred to above, and a kind of friction-type Subdivision head sheave wheel hub structure of being reliably fixedly connected with between head sheave wheel hub and spacer of ensureing is provided.
For addressing the above problem, friction-type Subdivision head sheave wheel hub structure of the present utility model adopts following structure:
A kind of friction-type Subdivision head sheave wheel hub structure, comprise Subdivision head sheave body, it wheel body is arranged on day wheel shaft by bearing shell, between it wheel body wheel hub and bearing shell, spacer is installed, it wheel body wheel hub and spacer adopt the connector structure that is connected to one, and wherein, described connector comprises locating dowel pin, two axial end portion faying faces of it wheel body wheel hub and spacer are provided with the hole of inserting for described locating dowel pin, and day wheel body wheel hub and spacer are connected to one by the locating dowel pin that inserts this hole.
Further, the described axial end portion of described sky wheel body wheel hub and spacer is provided with the back-up ring for preventing that described locating dowel pin from deviating from, and this back-up ring is fixed by screws on day wheel body wheel hub.
Further, run through described day wheel body wheel hub, spacer and bearing shell and be formed with lubrication channel, this lubrication channel is at bearing shell medial surface opening.
Owing to adopting said structure, the junction of the edges of two sheets of paper screw that the wheel body of head sheave and spacer are used changes finger setting into, then adds a back-up ring in wheel hub both sides and prevent that locating dowel pin from deviating from, and after improving, location firmly, has strengthened the integral rigidity of Subdivision head sheave wheel hub.
Brief description of the drawings
The Subdivision head sheave apparatus structure schematic diagram that accompanying drawing 1 is multi-rope friction hoisting machine;
Wherein: 1-days wheel bodys, 2-days wheel shafts, 3-days wheel body wheel hubs, 4-bearing shell, 5-spacer, 6-lubrication channel, 7-screw, 8-locating dowel pin, 9-back-up ring, 10-screw
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is elaborated.
As shown in accompanying drawing 1,3, friction-type Subdivision head sheave wheel hub structure comprises Subdivision head sheave body 1, it wheel body 1 is arranged on day wheel shaft 2 by bearing shell 4, between it wheel body wheel hub 3 and bearing shell 4, spacer 5 is installed, its wheel body wheel hub 3 and spacer 5 adopt the connector structure that is connected to one, wherein, described connector comprises locating dowel pin 8, it wheel body wheel hub 3 is provided with the hole of inserting for described locating dowel pin 8 with two axial end portion faying faces of spacer, and a day wheel body wheel hub 3 is connected to one by the locating dowel pin that inserts this hole with spacer 5.
Within described day, wheel body wheel hub 3 is provided with the back-up ring 9 for preventing that described locating dowel pin from deviating from the described axial end portion of spacer 5, and this back-up ring 9 is fixed on day wheel body wheel hub by screw 10.
Run through described day wheel body wheel hub 3, spacer 5 and bearing shell 4 and be formed with lubrication channel 6, this lubrication channel 6 is at bearing shell 4 medial surface openings, for lubricating oil being injected between bearing shell 4 and day wheel shaft 2.
The junction of the edges of two sheets of paper screw using by wheel body and the spacer of head sheave just changes finger setting into, and back-up ring is set in wheel hub both sides prevents that locating dowel pin from deviating from, and makes the structure location after improving firm, has strengthened the integral rigidity of Subdivision head sheave wheel hub.
