Description

Guide chain wheel

Technical Field

The utility model belongs to the technical field of drive sprocket technique and specifically relates to a leading sprocket.

Background

The chain wheel is a wheel with embedded tooth type buckling chain teeth and is used for being meshed with blocks with accurate pitches on chain links or cables, and the chain wheel is widely applied to mechanical transmission and the like in the industries of chemical engineering, textile machinery, escalators, wood processing, three-dimensional parking garages, agricultural machinery, food processing, instrument and instrument, petroleum and the like. The existing chain wheel is generally composed of a wheel body and wheel teeth, and the wheel teeth of the adjacent chain wheel are often displaced in the meshing transmission process, so that the condition that the wheel teeth are not completely meshed or separated from each other is caused, and the normal transmission operation is influenced.

SUMMERY OF THE UTILITY MODEL

In order to overcome the defects of the prior art, the utility model provides a guide chain wheel, which solves the problem by arranging a check ring for preventing the displacement on the outer side surface of the wheel tooth.

The utility model provides a technical scheme that its technical problem adopted is: the utility model provides a guide sprocket, includes wheel body and the teeth of a cogwheel, and the wheel body periphery evenly is provided with the teeth of a cogwheel that is used for meshing driven, and the wheel body is outer along being provided with the double-deck retaining ring that is used for the teeth of a cogwheel meshing direction, and double-deck retaining ring sets up respectively in teeth of a cogwheel both sides, is provided with the oil brush that is used for the teeth of a cogwheel lubrication on the opposite face of double-deck retaining ring, and.

Furthermore, the lateral surface of double-deck retaining ring flushes with the surface of wheel body, and the width and the teeth of a cogwheel height of double-deck retaining ring are the same.

Furthermore, the oil brush is hemispherical, an oil storage cavity is arranged inside the oil brush, and an oil outlet is formed in the outer surface of the oil brush.

Further, the oil brushes are arranged on the inner side face of the double-layer retainer ring in a staggered mode.

Further, the outer edge of the wheel body is provided with threads, and the double-layer check ring is detachably connected with the wheel body in a threaded mode.

The utility model has the advantages that the gear tooth meshing surface is guided by the retainer rings which are arranged on the outer edge of the wheel body and have the same height with the gear teeth, thereby effectively preventing the gear teeth from shifting or dropping off and ensuring the normal operation of the chain wheel transmission; the semi-spherical oil brushes which are arranged on the inner side surfaces of the retainer rings in a staggered manner are used for lubricating meshing gear teeth, so that the meshing effect is improved, and the transmission efficiency of the chain wheel is improved; realize the fixed to the retaining ring through the screw thread mode for convenient and fast is dismantled in the installation of retaining ring.

Drawings

The present invention will be further explained with reference to the drawings and examples.

Fig. 1 is a front view of the present invention;

fig. 2 is a side view of the present invention.

In the figure, 1, a wheel body, 2, gear teeth, 3, a double-layer retainer ring, 4, an oil brush, 5, an oil storage cavity and 6, an oil outlet are arranged.

Detailed Description

As fig. 1 is the utility model discloses a schematic structure diagram, a leading sprocket, including wheel body 1 and the teeth of a cogwheel 2, 1 periphery of wheel body evenly is provided with and is used for meshing driven teeth of a cogwheel 2, wheel body 1 is outer along being provided with the double-deck retaining ring 3 that is used for the teeth of a cogwheel 2 meshing direction, double-deck retaining ring 3 sets up respectively in the 2 both sides of the teeth of a cogwheel, the surface of oil brush 4 and the 2 meshing surface contacts of the teeth of a cogwheel of adjacent gear, double-deck retaining ring 3's lateral surface flushes with the surface of wheel body 1, double-deck retaining ring 3's width and the 2 highly the same of the teeth of a. This leading sprocket is on the basis of current sprocket, 2 outsides at the teeth of a cogwheel have set up double-deck retaining ring 3, and 1 outer edge at the wheel body sets up the external screw thread, make double-deck retaining ring 3's internal thread to connect with it, convenient and fast is dismantled in the installation, arrange the teeth of a cogwheel 2 in between double-deck retaining ring 3, when taking double-deck retaining ring 3's sprocket and ordinary sprocket to mesh the transmission, the teeth of a cogwheel of meshing 2 all are injectd between retaining ring 3, and it is fixed to carry out the chucking through hemisphere type oil brush 4 on the mating surface, the aversion condition of sprocket at meshing transmission in-process has been avoided, transmission.

As shown in fig. 2, an oil brush 4 for lubricating the gear teeth 2 is arranged on the opposite surface of the double-layer retainer ring 3, the oil brush 4 is of a hemispherical shape, an oil storage cavity 5 is arranged inside the oil brush 4, an oil outlet 6 is formed in the outer surface of the oil brush 4, and the oil brush 4 is arranged on the inner side surface of the double-layer retainer ring 3 in a staggered mode. Hemisphere type oil brush 4 can be dismantled fixedly through bolt and double-deck retaining ring 3, also can welded fastening at the medial surface of double-deck retaining ring 3, and oil brush 4 is inside for placing lubricating oil's oil storage chamber 5, and oil outlet 6 has been seted up to 4 tip of oil brush, and oil outlet 6 contacts with the teeth of a cogwheel meshing surface of adjacent sprocket just to at the sprocket feed in-process, carry out self-lubricate to the sprocket, in order to improve transmission efficiency.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
