Abstract
The utility model discloses a kind of compound spindle nose blanking cover, be applied on oil lubrication axletree, comprise blanking cover, stuffing box gland, described stuffing box gland is bonded on the outer surface of blanking cover, described blanking cover is arranged in the spindle nose hole of axletree, the spindle nose hole inner round wall interference fit of described blanking cover or stuffing box gland and axletree.Compound spindle nose blanking cover of the present utility model is used for oil lubrication axletree, and blanking cover and axis body are interference fit, and blanking cover is with outer field rubber and axis body close contact, so sealing is fine, can prevent lubricant oil from flowing into axis body cavity.
Description
Technical field
The utility model relates to trailer, semitrailer axle/bridge technical field, more particularly, relates to the compound spindle nose blanking cover of a kind of trailer, semitrailer axle/bridge.
Background technique
At present, on the axletree of trailer or semitrailer, axis body cavity is flow to for preventing the lubricant grease on axletree, often the end screwing type shaft-cup of spindle nose is sealed up, and install seal ring additional inside shaft-cup, though this structure can solve the problem that grease leaks, but shaft-cup is easily loose, reliability is bad.
Model utility content
The utility model is for solving the deficiencies in the prior art, the compound spindle nose blanking cover providing a kind of good airproof performance, reliability high.
The utility model solves the technological scheme that its technical problem adopts: a kind of compound spindle nose blanking cover, be applied on oil lubrication axletree, comprise blanking cover, stuffing box gland, described stuffing box gland is bonded on the outer surface of blanking cover, described blanking cover is arranged in the spindle nose hole of axletree, the spindle nose hole inner round wall interference fit of described blanking cover or stuffing box gland and axletree.
The auxiliary section that described blanking cover comprises cover plate, vertically bends along described side edge thereof.
Described stuffing box gland is oil resistant rubber.
The wall thickness reduction at the corresponding cover plate central position of described stuffing box gland.
Compared with prior art, the beneficial effects of the utility model are:
Compound spindle nose blanking cover of the present utility model is used for oil lubrication axletree, and blanking cover and axis body are interference fit, and blanking cover is with outer field rubber and axis body close contact, so sealing is fine, can prevent lubricant oil from flowing into axis body cavity.

Embodiment
Be described below in detail embodiment of the present utility model, the example of described embodiment is shown in the drawings, and wherein same or similar label represents same or similar element or has element that is identical or similar functions from start to finish.Being exemplary below by the embodiment be described with reference to the drawings, only for explaining the utility model, and can not being interpreted as restriction of the present utility model.
See Fig. 1-4, compound spindle nose blanking cover 1 of the present utility model is applied on oil lubrication axletree, is the part of the hollow back axle of oil lubrication of semitrailer, flows in axis body cavity for preventing lubricant oil.Compound spindle nose blanking cover 1 comprises blanking cover 2, stuffing box gland 3, and blanking cover is arranged in the hole of spindle nose 5 of axletree, and blanking cover comprises cover plate 12, along the auxiliary section 11 that side edge thereof vertically bends, thus forms the blanking cover of a shape like circular lid.Blanking cover is metal material, and stuffing box gland 3 is bonded on the outer surface of blanking cover, and stuffing box gland is oil resistant rubber.The external diameter of the compound spindle nose blanking cover be made up of metallic case and rubber outer is 20mm-120mm, and total wall thickness is 1mm-4mm, is highly 6mm-20mm.
Step 7 is provided with in the spindle nose hole of axletree, spindle nose hole inner round wall 6 interference fit of stuffing box gland 3 and axletree, in the hole being fixed on axis body head by interference fit and stuffing box gland 3 is resisted against on the step 7 in spindle nose hole, outer field oil resistant rubber directly and the inner round wall close contact in spindle nose hole, favorable sealing property.
Because compound spindle nose blanking cover mainly realizes and being sealed and matched of spindle nose hole with the auxiliary section of blanking cover and auxiliary section outer field stuffing box gland, therefore, for saving material, cutting the waste, by the stuffing box gland wall thickness reduction at corresponding cover plate central position, form thinning area 4, make structure more scientific and reasonable.
Below openly specific embodiment of the utility model is only; do not form the restriction to the utility model protection domain; for the utility model person of an ordinary skill in the technical field; do not departing under general idea prerequisite of the present utility model; according to technical solutions of the utility model do without the need to through the change of creative work and replacement, all should drop within protection domain of the present utility model.
