Description

A kind of roll assembly

Technical field

This utility model is related to tipper manufacturing technology field, more specifically, it relates to a kind of roll assembly.

Background technology

Roller is the general designation of the cylindrical parts that can roll on machine, common are carrying roller, roll, running roller etc., for all kinds of On machine, or rolling transmission, or roll pressure.On the cylinder tipper of horizontal, conventional running roller carrys out support cylinder, to justify The roll-over table of cartridge type by goods by horizontal be converted into vertical or by vertical be converted into horizontal, complete overturn operation.

But, when overturning operation, because load-bearing running roller bears all of weight on roll-over table, the bearing in load-bearing running roller Easy to wear by long-term use it is therefore desirable to regular roll shaft is cleared up, upper grease, or change, and carry running roller in order to Keep works fine in the work space of closing at bearing to adopt all kinds of seal approach, cause dismounting and change to be difficult.

Utility model content

In view of the shortcomings of the prior art, the purpose of this utility model is to provide a kind of roller of easy access bearing Wheel.

For achieving the above object, this utility model provides following technical scheme：A kind of roll assembly, including roll shaft, set The bearing being located on roll shaft and the roller set being set in outside bearing, described roll shaft and roller put and are separately provided for limiting at bearing In axial sliding raised one and projection on roll shaft, described roll shaft arranges fluted one, described groove one is provided with for Bearing is limited in spring collar one between the two by fitting projection one, and described roller puts setting fluted two, described groove two On be provided with for coordinating projection that bearing is limited in spring collar two between the two, described spring collar one and spring collar Two respectively with groove one and groove two clamping.

By adopting technique scheme, projection one on bearing and spring collar one to the axial fixing bearing of cooperation, Roller set is also fixed, when dismantling, installing only while cooperation axial fixing bearing by the spring collar two that roller puts and projection Spring collar two need to be taken off, roll shaft is pulled out, bearing will be carried over, maintenance is convenient, change quick.

This utility model is more preferably：Described raised one is provided with the spanner groove for convenient wrench clipping operation.

By adopting technique scheme, when the bearing in running roller is checked or changed, convenient use spanner presss from both sides Pull out from frame after holding roll shaft.

This utility model is more preferably：Described roller puts and is provided with for preventing dust from entering the dust cap in bearing, And dust cap is adsorbed on the opening of roller set.

By adopting technique scheme, dust cap is to prevent dust to be blown in bearing by roller set opening, The ball being thus avoided that in bearing enters, because of dust, the abrasion causing, and dust cap is adsorbed in roller running-on simultaneously, installation of taking away Fast.

This utility model is more preferably：Described dust cap is spliced by multiple fritters.

By adopting technique scheme, dust cap just can increase area coverage and the roller that simultaneously fits like a glove set open Mouthful.

This utility model is more preferably：The opening of described roller set is provided with and is easily installed spring collar two and puts in roller Interior chamfering.

By adopting technique scheme, interior chamfering one side can facilitate install spring collar two when opening is covered by roller Put in groove two, dirt-proof boot on the other hand can be coordinated to adsorb on opening.

This utility model is more preferably：Gap setting between one end of described roll shaft and roller set.

By adopting technique scheme, an end of roll shaft can make roller set with bearing rolling with the gap setting of roller set When, just there is not friction with the roll shaft portion of being not in contact with roller set, thus allow maintaining roller set smoothly to rotate.

This utility model is more preferably：Another end of described roll shaft is provided with circular hole, is provided with bolt in circular hole, and It is provided with pad between bolt and roll shaft.

By adopting technique scheme, bolt thus can be tightened by pad and a raised clamping frame or installation Seat, roll shaft is fixed in frame or mounting seat.

By adopting technique scheme, this utility model hinge structure is compared：By the projection one on bearing With spring collar one to the axial fixing bearing of cooperation, the spring collar two that roller puts and projection are same in the axial fixing bearing of cooperation When also roller set is fixed, only need to take off spring collar two when dismantling, installing, by roll shaft pull-out can complete change, also set up Spliced dust cap, and covered in roller by magnet absorption and connect, can either reach dust-proof effect it is also possible to fast quick-detach, peace Dress, easy access.
