Abstract

The utility model discloses a sealing and lubricating long pitch conveyor chain which carries out sealing and lubricating to a kinematic pair of a chain. A roller of the chain is composed of a roller core and a roller outer ring; an oil chamber is arranged in the roller core; stored lubricating oil passes through the roller core and an oil hole in the middle of a sleeve barrel, lubricates the matching surface among a pin shaft, the sleeve barrel and the roller, and utilizes two end-face oil seals to seal the matching surface and prevent the lubricating oil from draining outwards besides dust prevention. The utility model reduces the frictional resistance and lowers the abrasion and the energy consumption of the chain; the primary structure size and the mechanical property of the utility model is basically same to the standard pitch conveyor chain, and thus interchangeability is available.

Description

The seal lubrication meropodium is apart from conveyer chain

Technical field

The utility model relates to a kind of sealing, lubricated meropodium apart from conveyer chain.

Background technology

Existing meropodium is a kind of gauge member apart from conveyer chain; on the books at mechanical design handbook (publication of 1993.5 Chemical Industry Press) the second volume 8-103 page or leaf; because this conveyer chain motion space is very big, so be difficult to its integral sealing and dustproof, lubricating by the gap oiling between the part solves for a long time; it is lubricated to belong to the gap; lubricant effect is poor, adds not sealing, and dust gathers; friction drag is big, serious wear.

The utility model purpose reaches lubricated meropodium apart from conveyer chain for a kind of sealing is provided, and prevents that silt from entering, and has reduced frictional resistance, falls end chain wear and energy consumption.

For achieving the above object, meropodium of the present utility model is by the roller that is positioned on the sleeve apart from conveyer chain, the inboard carrier bar that is press-fitted with the sleeve two ends, be positioned at the bearing pin of sleeve, form with outside carrier bar and lateral oil seal that the bearing pin two ends are press-fitted, roller is made up of roller core and roller outer ring, the two is radially for being pressed into cooperation, the roller in-core has the grease chamber, oilhole by roller core and sleeve middle part lubricates fitting surface between bearing pin and sleeve and the roller, roller core two lateral surfaces have circular groove, there is the medial surface of lateral oil seal and inboard carrier bar to constitute sealing in the groove, there is circular groove carrier bar inboard, two outsides, in have the lateral surface of lateral oil seal and inboard carrier bar to constitute sealing.

After adopting said structure, owing to stored more lubricating oil in the roller grease chamber, because the both ends of the surface oil sealing makes lubricating oil be difficult for leaking, kinematic pair continuous lubrication and sealing have been realized to chain, prevent that silt from entering, reduced frictional resistance, fallen at the end chain wear and energy consumption.

Description of drawings

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.

Fig. 1 is that utility model seals, lubricates front view and the cutaway view of meropodium apart from the conveyer chain specific embodiment,

Fig. 2 is the bright sealing of utility model, the lubricated meropodium enlarged view apart from conveyer chain chain joint part.

The specific embodiment

Fig. 1 sealing shown in Figure 2, lubricated meropodium are apart from conveyer chain, its roller is made up of roller core 5 and roller outer ring 4, be enclosed within on the sleeve 3, sleeve 3 both sides heads, be pressed in the hole of inboard carrier bar 6, bearing pin 1 is positioned at sleeve 3 holes, bearing pin 1 both sides head is pressed in the hole of outside carrier bar 7, roller core 5 radially cooperates for being pressed into roller outer ring 4, be pressed into cooperation and can form liquid sealing, there is the c of grease chamber can store more lubricating oil in the roller core 5, lubricates fitting surface between bearing pin 1, sleeve 3, the roller core 5 by the oilhole a at roller core 5 middle parts and the oilhole b at sleeve 3 middle parts.Roller core two lateral surfaces have circular groove, have the lateral oil seal 2 and the medial surface of inboard carrier bar 6 to constitute sealing in the groove, and there is circular groove the inboard of two outside carrier bars 7, have the lateral oil seal 2 and the lateral surface of inboard carrier bar 6 to constitute sealing in the groove.The gap that lateral oil seal 2 sealing roller cores 5 and inboard carrier bar are 6, the gap that other end oil sealing 2 inboard carrier bars 6 of sealing and outside carrier bar are 7, the prevention lubricating oil leaks and is dustproof; Can rise during make-up oil and pull out plug cock 8, plug cock 8 afterbodys have locking elasticity convex shoulder.

Claims

1. a seal lubrication meropodium is apart from conveyer chain, by the roller that is positioned on the sleeve, the inboard carrier bar that is press-fitted with the sleeve two ends, be positioned at the bearing pin of sleeve, form with outside carrier bar and lateral oil seal that the bearing pin two ends are press-fitted, it is characterized in that: roller is made up of roller core and roller outer ring, the two is radially for being pressed into cooperation, the roller in-core has the grease chamber, this grease chamber is by the lubricated bearing pin of oilhole at roller core and sleeve middle part and the fitting surface between sleeve and the roller, roller core two lateral surfaces have circular groove, there are lateral oil seal and inboard carrier bar medial surface to constitute sealing in the groove, there is circular groove carrier bar inboard, two outsides, in have lateral oil seal and inboard carrier bar lateral surface to constitute sealing.
