Abstract
The utility model discloses a dustproof and slurry-proof idle pulley assembly, which comprises an idle pulley shaft (1) and an idle pulley (2) on the idle pulley shaft (1), wherein a dust cap (3) with a felt layer (4) is installed on the idle pulley (2), and a pair of bearings (5) is installed between the idle pulley shaft (1) and the idle pulley (2). A separation ring (6) is installed between the bearings (5), and a separation ring (7) is installed between the dust cap (3) and idle pulley (2). The dustproof and slurry-proof idle pulley assembly has an improved isolating capability for dust, water and slurry, and is capable of effectively isolating large dust particles, impurities, water and slurry, and reducing wearing of an idle pulley due to water and slurry, thereby lengthening the service lifetime of an idle pulley.
Description
Technical field
The utility model relates to a kind of mechanical transmission field of accessories, particularly a kind of dustproof anti-mud idle pulley assembly.
Background technique
In the mechanical transmission, idle pulley can be realized turning to of transmission, makes transmission system can realize the change of direction with the loss in efficiency of minimum, is very important constituent element in the mechanical transmission.In fact, very abominable of the working environment of transmission system, high temperature, high pressure, noise is big, dust is many, even under some very moist environment, turn round, moisture and dust very easily form mud and enter into transmission part, thereby influence transmission efficiency, component wear is accelerated simultaneously, shorten working life, and the dust cover of traditional idle pulley only adopts the isolation of layer of metal cover realization to dust, and is then relatively poor for the isolation effect of moisture, mud, moisture, mud enter idle pulley easily, hinder the rotation of idle pulley, reduce transmission efficiency, the wearing and tearing of idle pulley are also accelerated.
The model utility content
The purpose of this utility model promptly is to overcome the shortcoming of existing idle pulley, proposes a kind of dustproof anti-mud idle pulley assembly, can strengthen the isolation effect to dust, moisture and mud, improves the working life of idle pulley.
The purpose of this utility model is achieved through the following technical solutions: a kind of dustproof anti-mud idle pulley assembly, comprise idler shaft and the idle pulley that is positioned on the idler shaft, one end of described idle pulley has been installed dust cover, be provided with felt layers on the dust cover, bigger dust and the impurity of dust cover energy spacer particles, felt layers can be isolated moisture and mud effectively, between idler shaft and idle pulley pair of bearings is installed.
Spacer ring also has been installed between the described bearing.
Between described dust cover and the idle pulley spacer ring has been installed.
Described dust cover is provided with fixed hole.
The beneficial effects of the utility model show: dust cover has been installed on the idle pulley, be provided with felt layers on the dust cover, bigger dust and the impurity of dust cover energy spacer particles, felt layers can be isolated moisture and mud effectively, strengthened isolation effect to dust, moisture and mud, the wearing and tearing of moisture and mud have been reduced, the working life of having improved idle pulley to idle pulley.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Fig. 2 is a plan view of the present utility model
Among the figure, 1-idler shaft, 2-idle pulley, 3-dust cover, 4-felt layers, 5-bearing, 6-spacer ring, 7-spacer ring, 8-fixed hole.
Embodiment
Below in conjunction with accompanying drawing the utility model is used to be further described, but that protection domain is not limited to is described.
As Fig. 1, Fig. 2, a kind of dustproof anti-mud idle pulley assembly comprises idler shaft 1 and the idle pulley 2 that is positioned on the idler shaft 1, and an end of described idle pulley 2 has been installed dust cover 3, is provided with felt layers 4 on the dust cover 3, and 2 of idler shaft 1 and idle pulleys are equipped with pair of bearings 5.
Between the described bearing 5 spacer ring 6 has been installed also.
Between described dust cover 3 and the idle pulley 2 spacer ring 7 has been installed.
Described dust cover 3 is provided with three fixed holes 8, but construction bolt positions in the fixed hole 8.
During work, dust cover 3 and felt layers 4 spacer particles is bigger effectively dust, impurity and moisture and mud prevent that moisture and mud from entering into the rotation that bearing 5, spacer ring 6 and spacer ring 7 influence idle pulley.
Claims (4)
1. dustproof anti-mud idle pulley assembly, comprise idler shaft (1) and be positioned at idle pulley (2) on the idler shaft (1), it is characterized in that: an end of described idle pulley (2) has been installed dust cover (3), be provided with felt layers (4) on the dust cover (3), between idler shaft (1) and idle pulley (2) pair of bearings (5) be installed.
