Abstract

The utility model provides a kind of big carrying idle pulley axle construction, including casing, idler shaft, bolt, sealing ring, idle pulley, back-up ring, spacer ring, roller, resilient key, bolt and pressing plate, idler shaft is installed on casing, fastened, carried between idler shaft and idle pulley using double-row roller using bolt, there is groove on idler shaft, and sealing ring is installed, spacer ring interval is used between two row's rollers, spacer ring is installed in idle pulley hole, positioned using back-up ring.Roller between idler shaft and idle pulley of the present utility model is small relative to plain bearing diameter, radial dimension can be effectively saved under same space, enlarged relative idler shaft diameter dimension, the roller of same outer diameter is bigger compared with the bearing load carrying capacity with Internal and external cycle, the bearing capacity of this structure is so increased significantly, and the oil jet lubrication of oil duct equally also greatly improves service life.

Description

Big carrying idle pulley axle construction
Technical field
The utility model is related to a kind of construction machinery gear box with big carrying idle pulley axle construction.
Background technology
At present, construction machinery gear box is in order to realize different outbound courses, and the scheme used substantially is one idle pulley of increase, Idle pulley is engaged with two gears, and the rotation direction for changing driven gear is allowed to identical with driving gear.Idle pulley is in driving wheel and quilt The power of both direction is carry between driving wheel, the power that idle pulley is born is that driving wheel is made a concerted effort with being superimposed for follower.Idle pulley with it is lazy Relative rotation between wheel shaft generally uses loading ability of bearing, in actual production, and due to making a concerted effort, larger and structure is limited, and is frequently resulted in The damage of idler shaft and cause gearbox to fail.
The content of the invention
The purpose of this utility model is to provide a kind of big carrying idle pulley axle construction, and the idle pulley axle construction is using big carrying knot Structure, reliability is high, and simple in construction, easily realizes.
A kind of big carrying idle pulley axle construction, including casing, idler shaft, bolt, sealing ring, idle pulley, back-up ring, spacer ring, roller, Resilient key, bolt and pressing plate, idler shaft are installed on casing, are fastened using bolt, and double rolling is used between idler shaft and idle pulley Post is carried, and has groove on idler shaft, and is installed and used spacer ring interval between sealing ring, two row's rollers, and spacer ring is installed in idle pulley hole, Positioned using back-up ring.
Also there is oil duct groove and oil duct, lubricating oil provides forced feed lubrication by the oil duct for roller on idler shaft.
Pressing plate is installed in the medial surface of idler shaft using bolt and with elastic pin connection.
Roller between idler shaft and idle pulley of the present utility model is small relative to plain bearing diameter, can under same space Effectively to save radial dimension, enlarged relative idler shaft diameter dimension, the roller of same outer diameter is held compared with the bearing with Internal and external cycle Loading capability is bigger, and the bearing capacity of this structure is so increased significantly, and the oil jet lubrication of oil duct equally also greatly improves service life. This other structure is relatively easy, is easily realized in assembling.
Brief description of the drawings
Fig. 1 is the utility model structure chart.
In figure:1st, casing, 2, idler shaft, 3, bolt, 4, sealing ring, 5, idle pulley, 6, back-up ring, 7, spacer ring, 8, roller, 9, bullet Property pin, 10, bolt, 11, pressing plate.
Embodiment
As shown in figure 1, a kind of big carrying idle pulley axle construction of the present utility model, by 1 casing, 2 idler shafts, 3 bolts, 4 close Seal, 5 idle pulleys, 6 back-up rings, 7 spacer rings, 8 rollers, 9 resilient keys, 10 bolts, 11 pressing plates are assemblied;2 idler shafts are installed on 1 casing On, fastened using 3 bolts, 2 idler shafts are connected with 1 gear housing rigidity;There is groove on 2 idler shafts, 4 sealing rings are installed for close Envelope;Carried between 2 idler shafts and 5 idle pulleys using double 8 roller, with 7 spacer ring intervals, 7 spacer rings and 5 idle pulleys between the roller of two row 8 On be respectively provided with a circlip groove, 7 spacer rings are installed in 5 idle pulley holes, utilize 6 back-up rings positioning;11 pressing plates are installed on 2 using 10 bolts In the medial surface of idler shaft and with 9 elastic pin connections, 11 press plate rotaries are prevented.Also there is oil duct groove and oil duct, oil on 2 idler shafts Liquid enters 2 idler shafts from 1 casing and then cooled down through oil channel for the working face between 8 rollers, 5 idle pulleys and 2 idler shaft threes And lubrication.
