Abstract
A kind of heavily loaded leaf chain sheave is the utility model is related to, is made up of sheave outer barrel, sheave inner support, bearing pin, bearing, bearing sleeve, mandrel etc..Leaf chain is used for crane gear, such as fork truck, there is that bearing load is big, and reliability is high, fatigue proof advantage, has important application in low speed big load drive apparatus.It is traditional it is heavily loaded it is board-like with key way wheel diameter is big, width is big, it is necessary to which multiple bearings are mounted side by side, there is the shortcomings that weight is big, installing space is big, installation is inconvenient.The design uses fabricated structure, and bearing is arranged on inside sheave support installation inside corresponding sheave, reduces the installing space of sheave needs, while installation causes the assembling of sheave to be more convenient one by one for bearing, support.The shortcomings that weight that novel load-carrying leaf chain overcomes the heavily loaded leaf chain sheave of tradition with sheave is big, installation space-consuming is big, installation is inconvenient.It disclosure satisfy that low speed big load drive apparatus requirement.
Description
Technical field
It the utility model is related to a kind of heavily loaded leaf chain sheave, it is more particularly to a kind of for large-scale heavy duty drive apparatus
Leaf chain sheave.
Background technology
Leaf chain has that bearing load is big, and reliability is high, fatigue proof advantage, has in low speed big load drive apparatus
Important application.But the diameter of the heavily loaded leaf chain sheave of traditional structure is big, width is big, weight is big, and heavy duty is board-like
Chain is needed to be equipped with multiple rows of heavy-duty bearing with sheave, and the space taken on drive apparatus is big, and installs inconvenience, therefore
Need to design a kind of occupying little space suitable for heavy load transmission equipment, leaf chain sheave easy for installation.
Utility model content：
The utility model aims to solve the problem that above mentioned problem, devises a kind of novel load-carrying leaf chain sheave, and it overcomes biography
Unite heavily loaded leaf chain sheave weight is big, the shortcomings that installation space-consuming is big, installation is inconvenient, the technical scheme that it is used is such as
Under：
Novel load-carrying leaf chain sheave, including：Outer barrel, sheave inner support, bearing pin, cylinder roller bearing, mandrel, opening
Pin, bearing sleeve, described outer barrel are interference fitted with inner support, and the via clearance on described bearing pin and inner support coordinates, institute
The split pin stated is connected with bearing pin, and described cylinder roller bearing is arranged among inner support and mandrel, the bearing sleeve with
Mandrel gap coordinates the installation for facilitating cylinder roller bearing.
Cylinder roller bearing is arranged on sheave inner support and core inside sheave in above-mentioned novel load-carrying leaf chain sheave
Among axle, space-consuming is reduced.
Above-mentioned novel load-carrying leaf chain can be installed one by one with cylinder roller bearing in sheave, after sheave assembling is completed
Direct integral installation is on drive apparatus so that sheave assembling is simpler, and installation is more convenient.
The utility model has the following advantages that：Small volume, in light weight, bearing is arranged on inside sheave, installs space-consuming
It is small.Bearing, sheave inner support can be installed one by one, and sheave assembling is simple, and sheave is directly installed on drive apparatus after integrally assembling
On, it is easy for installation
Brief description of the drawings

Fig. 2：The utility model heavy duty leaf chain sheave entirety inner supporting structure schematic diagram；
Symbol description
1. outer barrel, 2. sheave inner supports, 3. bearing pins, 4. bearings, 5. mandrels, 6. split pins, 7. sleeves.
Embodiment：
The utility model patent is described further with example below in conjunction with the accompanying drawings：
As depicted in figs. 1 and 2, heavily loaded leaf chain sheave of the present utility model, including：Outer barrel 1, sheave inner support 2, pin
Axle 3, cylinder roller bearing 4, mandrel 5, split pin 6, bearing sleeve 7, described outer barrel 1 is interference fitted with inner support 2, described
Bearing pin 3 coordinates with the via clearance in inner support 2, and described split pin 6 is connected with bearing pin 3, and described cylinder roller bearing 4 is pacified
Among inner support 2 and mandrel 5, the bearing sleeve 7 coordinates the installation for facilitating cylinder roller bearing 4 with the gap of mandrel 5.
New heavily loaded leaf chain is assembled with sheave and mounting means：First by sleeve 7, cylinder roller bearing 4, sheave
The packet of support 2 is arranged on mandrel 5 by group.Then bearing pin 3 is arranged in sheave inner support 2 and fixed with split pin 6, finally will
Outer barrel 1 is arranged in inner support 2, and heavily loaded leaf chain is assembled with sheave and completed.The heavily loaded leaf chain that assembling is completed is passed through with sheave
Mandrel both ends are arranged in heavy load transmission equipment.
