Abstract
A novel flywheel assembly belongs to the technical field of flywheel machinery. The conventional flywheel and the bearing which are connected in an interference fit manner have the defect of difficulty in mounting and detaching. The novel flywheel assembly is mainly characterized in that a rear bearing seat connected with a bearing outer ring is arranged between the bearing and the flywheel, is a hollow cylinder, and has one end with a turned-over edge; a plurality of screw holes are symmetrically arranged on a bearing cover and the turned-over edge of the rear bearing seat; the screw holes are formed on the flywheel in the positions corresponding to the screw holes; and the bearing cover and the rear bearing seat are fastened and connected through screws. By arranging a connecting piece between the flywheel and the bearing, the flywheel is connected with the bearing through the detachable connecting piece, and the interference fit is eliminated, as a result, the bearing and the flywheel are convenient to mount and detach, thereby greatly improving production and maintenance efficiencies.
Description
One. technical field
The utility model belongs to the flywheel mechanical field, and is especially relevant with a kind of novel fly wheel assembly.

Flywheel is mounted in the colyliform accumulator than large rotating inertia of having on the machine turning axle.When machine rotational speed increased, the kinetic energy of flywheel increased, and energy is stored up; When machine rotational speed reduced, flywheel energy reduced, and energy is discharged.Flywheel can be used for reducing the speed fluctuation of machine operation process.At present, fly wheel assembly generally is made up of flywheel, gear ring, clutch locating stud, bearing etc., transmission shaft is threaded onto bearing inner race, it is that interference fit connects that bearing outer ring is connected by tensioner with flywheel, again because flywheel is general bigger, and heavier, so bearing is connected back dismounting inconvenience with the flywheel interference fit, the bearing after installing is difficult to split.
Three. summary of the invention
The purpose of this utility model is exactly will overcome existing bearing to be connected by tensioner with flywheel and to have the defective of installing, splitting inconvenience, the installation of a kind of bearing and flywheel is provided and splits fly wheel assembly easily, and the utility model provides following technological scheme for this reason:
A kind of novel fly wheel assembly, comprise flywheel, bearing, flywheel inner sleeve, Case of fly-wheel ring and bearing cap, bearing cap lid is loaded on the bearing outer side surface bearing that reclines, prevent the bearing displacement, flywheel sleeve is contained in outside the bearing, flywheel inner sleeve, Case of fly-wheel ring set are loaded on bearing, carry out spacing to bearing inner race and bearing outer ring respectively, bearing inner race is fixedlyed connected with transmission shaft, it is characterized in that: be provided with the rear bearing block that is connected with bearing outer ring between described bearing and the flywheel, this rear bearing block is the cylindrical body of hollow, and an end has flange; The flange of described bearing cap and rear bearing block is provided with screw hole, this screw hole is symmetrical arranged a plurality of, the position that flywheel is corresponding with described screw hole is provided with screw hole, and bearing cap, rear bearing block are fastenedly connected by screw, when this fly wheel assembly need split, only need turn on screw, open bearing cap, bearing just can separate with flywheel, therefore, install, fractured operation is convenient.
As the further of technique scheme improved and replenish, the utility model also comprises following additional technical feature:
Flange outer rim on the described rear bearing block is provided with positioning step.
Described bearing cap is circular, and its outer rim is provided with boss, and this boss and described step are chimeric, are fastened on the positioning step and can carry out spacing to bearing cap by boss.
The cylindrical body outer wall of described rear bearing block and flywheel surface of contact intermediate section are provided with shallow slot, are provided with the oilhole that at least one connects rear bearing block at the shallow slot place.
Described flywheel is provided with an oil hole, and this oil hole is communicated with the shallow slot of flywheel outside and rear bearing block.
Oilhole corresponding part on described Case of fly-wheel ring and the rear bearing block is provided with at least one through hole, and to shallow slot, extruded lubricating ring is around shallow slot by oil hole for lubricant oil, and around infiltrating bearing by oilhole and through hole bearing is lubricated.
Screw hole on the described bearing cap is the indent screw, can the receive bolts head.
Be set with left and right two seal rings on the described transmission shaft, right seal ring embeds in the bearing cap, and left seal ring is installed in the bottom that rear bearing block does not have lapped pipe end, and two seal rings seal about to bearing, prevent that lubricant oil from leaking.
The utility model has the advantages that: by link (rear bearing block) is set between flywheel and bearing, by detachable link flywheel is connected with bearing, the cancellation interference fit, thus can make bearing and flywheel install, split conveniently, improved production and maintenance efficiency greatly.
