Abstract

The embodiment of the utility model discloses a reduction box which comprises a box body, a transmission shaft and a distance ring, wherein a bearing is arranged on a bearing installation seat on the box body, and an end cover is arranged at a port of the bearing installation seat; the end part of the transmission shaft is arranged on the bearing; and the distance ring is arranged between the bearing and the end cover, and two sides of the distance ring are respectively contacted with the bearing and a bayonet of the end cover. For the reduction box, after the distance ring is installed, two side surfaces of the distance ring are respectively contacted with the bayonet of the end cover and the outer end surface of the bearing, thus avoiding the condition that an adjusting gasket needs to be arranged as an original distance ring is too high or tool low, and avoiding the situation of oil leakage or the abrasion of the contact surface of the bearing and a gear due to the abrasion of the adjusting gasket during the work of the reduction box.

Description

Speed reducer
Technical field
The utility model relates to reduction gear mechanism technology for making field, more particularly, relates to a kind of speed reducer.
Background technique
In the existing speed reducer, distance ring is placed between bearing and the end cap, and end cap is through being bolted on the casing; In the process of assembling; Too high or the low excessively situation of distance ring can be occurred,, the slit will be occurred between end cap and the casing so if distance ring is too high; Need between end cap and casing, add the adjustment pad, to guarantee being sealed and matched between casing and the end cap; If distance ring is low excessively, need add the adjustment pad between end cap and the distance ring, guarantee that the clamping and positioning between each parts cooperates.
But in the working procedure of speed reducer; Along with the rotation of each transmission shaft in the speed reducer,, be arranged on the spacer sector-meeting wearing and tearing between casing and the end cap so if distance ring is too high; And then make that the adjustment pad is ineffective, can cause hidden danger such as speed reducer leakage of oil.
If above-mentioned distance ring is low excessively; Adjust pad so and be arranged between end cap and the distance ring, in the working procedure of speed reducer, spacer sector-meeting wearing and tearing; The residual cognition of adjustment pad that comes off through wearing and tearing enters into speed reducer, causes the wearing and tearing of the surface of contact of bearing or gear.
The model utility content
In view of this, the utility model provides a kind of speed reducer, so that a kind of speed reducer of avoiding adopting the adjustment pad to be provided, to avoid the leakage of oil that the spacer pad wear causes or the situation of gear-box inner piece wearing and tearing.
In order to achieve the above object, the utility model embodiment provides following technological scheme:
A kind of speed reducer comprises:
Casing, the Bearing Installation seat on the said casing is provided with bearing, and the port of said Bearing Installation seat is provided with end cap;
Be arranged on the transmission shaft on the said bearing;
Also comprise the distance ring that is arranged between said bearing and the said end cap, the both sides of said distance ring contact with the seam of said end cap and the exterior edge face of said bearing respectively.
In the speed reducer that the utility model embodiment provides; After distance ring is installed; Its bi-side contact with the seam of end cap and the exterior edge face of bearing respectively; In the speed reducer that the utility model embodiment provides, avoided existing distance ring too high or cross low and the situation of adjustment pad need be set, avoided speed reducer in the process of work since the wearing and tearing of adjustment pad cause leakage of oil or cause the contact surface abrasion of bearing, gear.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technological scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiments of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
The part-structure schematic representation of the speed reducer that Fig. 1 provides for the utility model embodiment.
Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technological scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is a part of embodiment of the utility model, rather than whole embodiments.Based on the embodiment in the utility model, the every other embodiment that those of ordinary skills are obtained under the prerequisite of not making creative work belongs to the scope that the utility model is protected.
The utility model provides a kind of speed reducer, and this speed reducer has been avoided the use of adjustment pad, and then the situation of having avoided leakage of oil that the spacer pad wear causes or gear-box inner member to damage.
Please refer to accompanying drawing 1, the part-structure schematic representation of the speed reducer that Fig. 1 provides for the utility model embodiment.
The speed reducer that the utility model embodiment provides comprises casing 4, end cap 2, transmission shaft 1, bearing 3, gear 5 and gear 6, wherein:
Bearing Installation seat on the casing 4 is provided with bearing 3, and the port of Bearing Installation seat is provided with end cap 2;
Be installed in the transmission shaft 1 on the said bearing 3, it is provided with gear 5, and with gear 6 engagement driving of adjacent level;
Distance ring 7 is arranged between bearing 3 and the end cap 2, and the both sides of distance ring 7 contact with the exterior edge face of bearing 3 and the seam 21 of end cap 2 respectively.
In the speed reducer that the utility model embodiment provides; After distance ring is installed; Its bi-side contact with the seam 21 of end cap 2 and the exterior edge face of bearing 3 respectively; In the speed reducer that the utility model embodiment provides, avoided existing distance ring too high or cross low and the situation of adjustment pad need be set, avoided speed reducer in the process of work since the wearing and tearing of adjustment pad cause leakage of oil or cause the contact surface abrasion of bearing, gear.
To the above-mentioned explanation of the disclosed embodiments, make related domain professional and technical personnel can realize or use the utility model.Multiple modification to these embodiments will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiments shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
