Abstract

The utility model relates to a casing for a worm speed reducer, aiming to solve the technical problem that the rear cover and the middle shell need to be arranged into a whole body. The casing for the worm speed reduce comprises a casing body (1) with two arc side faces and a rear cover (2), which together form a worm speed reducer mounting cavity; arc concave surfaces are arranged at two side faces of the casing body (1); raised reinforcing ribs (1-1) are arranged on the concave surfaces; and raised X-shaped reinforcing ribs (2-1) are arranged on the rear cover. The casing for the worm speed reducer is characterized in that the casing body (1) and the rear cover (2) are integral.

Description

The worm gear reducer engine housing

Technical field

The utility model relates to a kind of parts of speed reducer, specifically is a kind of worm gear reducer engine housing.

Background technique

In the prior art, the worm gear reducer engine housing generally is divided into protecgulum, mesochite and bonnet three parts, and the bi-side of mesochite are cambered surface, bonnet by screw on mesochite.Because bonnet and mesochite are splits, this has increased manufacturing, assembly cost; And there is a junction plane between two-part, influential to transmission of heat.

Summary of the invention

The utility model technical issues that need to address are that bonnet and mesochite are designed to one.

Worm gear reducer engine housing of the present utility model, a housing and the back cover portion that bi-side are cambered surface forms the worm reduction gear installation cavity jointly; There is arc-shaped concave the housing bi-side, and the concave surface epirelief has stiffening rib, and protruding behind the back cover portion have an X-shaped stiffening rib, it is characterized in that described housing and back cover portion are one.After housing and the back cover portion one, the one, former two-part transmission of heat intercepts and is overcome, and its radiating efficiency also has raising; The 2nd, integrity rigidity has raising, can also economical with materials.With the WPA100 type is example, and the weight the during cast of bonnet and housing one is 19.1kg, bonnet during with housing split cast weight be respectively 3.8kg and the 17.2kg weight 21kg that adds up, material economy 1.9kg.

As preferably, housing and back cover portion, with and on stiffening rib and X-shaped stiffening rib be integrally casting.

As preferably, housing and the back cover portion joint line in installation cavity the thinnest wall thickness 〉=6mm outside housing; The face on described joint line both sides has curving of castings r.

The utility model housing and bonnet one, characteristics such as it is higher to have rigidity, and radiating effect is better have also reduced manufacture cost.

Embodiment

Below by embodiment, the technical solution of the utility model is described in further detail.

Embodiment 1.See Fig. 1,2, this routine worm gear reducer engine housing belongs to the WPA100 model, and housing is provided with tank filler sleeve 4 and drain oil 5, and boss 6 is arranged in the housing installation cavity.Housing 1 bi-side are cambered surface, it and back cover portion 2 be with the HT200 material by the casting all-in-one-piece, form worm reduction gear installation cavity (install refill behind the worm reduction gear join protecgulum get final product) jointly.Its middle shell 1 and the joint line of back cover portion 2 in installation cavity the thinnest thickness outside housing 1 are 6.5mm; The curving of castings r of the face on joint line both sides, this routine r is 1～3mm.There is arc-shaped concave housing 1 bi-side, and the concave surface epirelief has three horizontal one perpendicular stiffening rib 1-1 (see figure 3)s, and back cover portion is protruding X-shaped stiffening rib 2-1 (see figure 4).

Claims

1, a kind of worm gear reducer engine housing, a housing (1) and the back cover portion (2) that bi-side are cambered surface forms the worm reduction gear installation cavity jointly; There is arc-shaped concave housing (1) bi-side, and the concave surface epirelief has stiffening rib (1-1), and protruding behind the back cover portion have an X-shaped stiffening rib (2-1), it is characterized in that described housing (1) and back cover portion (2) are one.

2, worm gear reducer engine housing according to claim 1 is characterized in that described housing (1) and back cover portion (2), with and on stiffening rib (1-1) and X-shaped stiffening rib (2-1) be integrally casting.

3, worm gear reducer engine housing according to claim 1 and 2 is characterized in that described housing (1) and the joint line of back cover portion (2) in installation cavity the thinnest wall thickness 〉=6mm outside housing (1).

4, worm gear reducer engine housing according to claim 3 is characterized in that the face on described joint line both sides has curving of castings r.
