Abstract
The invention relates to a shell type saw disc. The shell type saw disc comprises a saw disc body and a shell. The shell extends from the surface nearby saw tooth roots of the saw disc body towards the vertical direction of the center of the saw disc body to form a hollow sealed structure, and a bearing is disposed on the surface plane of the center of the shell. A certain vertical space is reserved between the bearing and the cutting surface of the saw disc body, and splashing objects are few. Besides, by means of gravity action and the inclination angle of the shell, sundries are not prone to being accumulated to the bearing, the continuous working period of the saw disc body is remarkably prolonged, and in severe working environments, the effects are especially obvious.
Description
【Technical field】
The present invention relates to a kind of component of machine, particularly relate to sealed saw disc.
【Background technology】
After master craftsman of the Spring and Autumn period's invention saw, saw is widely used in the middle of life, instantly, saw disc is also widely used in life as the one of saw, and along with the development of industrial level, the rotating speed of saw disc has been far from hand saws and can compare, saw disc is also employed in the working environment become increasingly complex, such as harvesting Caulis Sacchari sinensis etc., under the complex working condition doing rotating speed, it is easy to occur that situation about stumbling rolled up by saw disc bearing by foreign material.
【Summary of the invention】
It is an object of the invention to provide and a kind of allow bearing away from the shell-type saw disc of rotating face, it is intended to solve foreign material and be easily accessible saw disc bearing, the problem affecting saw disc continuous firing.
The technical solution used in the present invention is: a kind of shell-type saw disc, and including saw disc and housing, described housing is extended by the vertical direction to saw disc center of the surface near saw disc sawtooth root and forms hollow sealing structure, and the table Plane Installation at the center of housing has bearing.
The further technical scheme of the present invention is: described housing is positioned at the upper surface of saw disc.
The further technical scheme of the present invention is: described housing is positioned at the lower surface of saw disc.
The further technical scheme of the present invention is: the upper and lower surface of described saw disc has housing.
The further technical scheme of the present invention is: described housing and saw disc are integral moldings.
The invention has the beneficial effects as follows: owing to using technique scheme, bearing has certain vertical space with the facet of saw disc, splash is less, and owing to action of gravity and housing are by the existence at inclination angle, foreign material are difficult to be stacked into bearing, significantly improve the continuous working period of saw disc, in harsh environments, effect is especially apparent.
【Accompanying drawing explanation】
Fig. 1 is the Facad structure schematic diagram of shell-type saw disc of the present invention；
Fig. 2 is the side structure schematic diagram of shell-type saw disc of the present invention.
【Detailed description of the invention】
The present invention is described further with detailed description of the invention below in conjunction with the accompanying drawings.
Shell-type saw disc as depicted in figs. 1 and 2, described shell-type saw disc includes saw disc 1 and housing 2, described housing 2 is extended by the vertical direction to saw disc center of the surface near saw disc sawtooth root and forms hollow sealing structure, table Plane Installation at the center of housing 2 has bearing, described housing 2 can be italic shape, can also be stepped, described shell-type saw disc according to working environment difference can be one side shell structure can also be two-sided shell structure, described saw disc can no longer offer axis hole, shell-type saw disc can allow bearing away from saw disc operating position, when being prevented from working in the most severe working environments such as sugarcane harvesting, the foreign material such as leaf are caused to be involved in the phenomenon of saw disc axle；Described bearing is sealed bearing, can reduce the impact that saw disc is operated by foreign material further.
Housing and saw disc can use movable connection, it would however also be possible to employ integral molding, and movable connection is easy to transform existing saw disc, and the production technology of integral molding is the easiest and sealing property is higher.
When existing saw disc is installed additional housing, owing to the center of existing saw disc is with axis hole, so for direction of rotation and the difference of the requirement of sealing surface, will select to be installed on described housing upper surface or the lower surface of saw disc, or the upper and lower surface of described saw disc has housing.For brand-new shell-type saw disc, when producing should according to cutting moment and saw disc requirement of strength choose whether to need to open at saw disc center axis hole, saw disc and housing all connect bearing time, the stability of shell-type saw disc is more preferable, but cost can be slightly higher, and sealing effectiveness also decreases.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent and improvement etc. made within the spirit and principles in the present invention, should be included within the scope of the present invention.
